Desarrollo de metodologías para mejorar la estimación de los hidrogramas de diseño para el cálculo de los órganos de desagüe de las presas

En la presente Tesis se ha llevado a cabo el contraste y desarrollo de metodologías que permitan mejorar el cálculo de las avenidas de proyecto y extrema empleadas en el cálculo de la seguridad hidrológica de las presas. En primer lugar se ha abordado el tema del cálculo de las leyes de frecuencia de caudales máximos y su extrapolación a altos periodos de retorno. Esta cuestión es de gran relevancia, ya que la adopción de estándares de seguridad hidrológica para las presas cada vez más exigentes, implica la utilización de periodos de retorno de diseño muy elevados cuya estimación conlleva una gran incertidumbre. Es importante, en consecuencia incorporar al cálculo de los caudales de diseño todas la técnicas disponibles para reducir dicha incertidumbre. Asimismo, es importante hacer una buena selección del modelo estadístico (función de distribución y procedimiento de ajuste) de tal forma que se garantice tanto su capacidad para describir el comportamiento de la muestra, como para predecir de manera robusta los cuantiles de alto periodo de retorno. De esta forma, se han realizado estudios a escala nacional con el objetivo de determinar el esquema de regionalización que ofrece mejores resultados para las características hidrológicas de las cuencas españolas, respecto a los caudales máximos anuales, teniendo en cuenta el numero de datos disponibles. La metodología utilizada parte de la identificación de regiones homogéneas, cuyos límites se han determinado teniendo en cuenta las características fisiográficas y climáticas de las cuencas, y la variabilidad de sus estadísticos, comprobando posteriormente su homogeneidad. A continuación, se ha seleccionado el modelo estadístico de caudales máximos anuales con un mejor comportamiento en las distintas zonas de la España peninsular, tanto para describir los datos de la muestra como para extrapolar a los periodos de retorno más altos. El proceso de selección se ha basado, entre otras cosas, en la generación sintética de series de datos mediante simulaciones de Monte Carlo, y el análisis estadístico del conjunto de resultados obtenido a partir del ajuste de funciones de distribución a estas series bajo distintas hipótesis. Posteriormente, se ha abordado el tema de la relación caudal-volumen y la definición de los hidrogramas de diseño en base a la misma, cuestión que puede ser de gran importancia en el caso de presas con grandes volúmenes de embalse. Sin embargo, los procedimientos de cálculo hidrológico aplicados habitualmente no tienen en cuenta la dependencia estadística entre ambas variables. En esta Tesis se ha desarrollado un procedimiento para caracterizar dicha dependencia estadística de una manera sencilla y robusta, representando la función de distribución conjunta del caudal punta y el volumen en base a la función de distribución marginal del caudal punta y la función de distribución condicionada del volumen respecto al caudal. Esta última se determina mediante una función de distribución log-normal, aplicando un procedimiento de ajuste regional. Se propone su aplicación práctica a través de un procedimiento de cálculo probabilístico basado en la generación estocástica de un número elevado de hidrogramas. La aplicación a la seguridad hidrológica de las presas de este procedimiento requiere interpretar correctamente el concepto de periodo de retorno aplicado a variables hidrológicas bivariadas. Para ello, se realiza una propuesta de interpretación de dicho concepto. El periodo de retorno se entiende como el inverso de la probabilidad de superar un determinado nivel de embalse. Al relacionar este periodo de retorno con las variables hidrológicas, el hidrograma de diseño de la presa deja de ser un único hidrograma para convertirse en una familia de hidrogramas que generan un mismo nivel máximo en el embalse, representados mediante una curva en el plano caudal volumen. Esta familia de hidrogramas de diseño depende de la propia presa a diseñar, variando las curvas caudal-volumen en función, por ejemplo, del volumen de embalse o la longitud del aliviadero. El procedimiento propuesto se ilustra mediante su aplicación a dos casos de estudio. Finalmente, se ha abordado el tema del cálculo de las avenidas estacionales, cuestión fundamental a la hora de establecer la explotación de la presa, y que puede serlo también para estudiar la seguridad hidrológica de presas existentes. Sin embargo, el cálculo de estas avenidas es complejo y no está del todo claro hoy en día, y los procedimientos de cálculo habitualmente utilizados pueden presentar ciertos problemas. El cálculo en base al método estadístico de series parciales, o de máximos sobre un umbral, puede ser una alternativa válida que permite resolver esos problemas en aquellos casos en que la generación de las avenidas en las distintas estaciones se deba a un mismo tipo de evento. Se ha realizado un estudio con objeto de verificar si es adecuada en España la hipótesis de homogeneidad estadística de los datos de caudal de avenida correspondientes a distintas estaciones del año. Asimismo, se han analizado los periodos estacionales para los que es más apropiado realizar el estudio, cuestión de gran relevancia para garantizar que los resultados sean correctos, y se ha desarrollado un procedimiento sencillo para determinar el umbral de selección de los datos de tal manera que se garantice su independencia, una de las principales dificultades en la aplicación práctica de la técnica de las series parciales. Por otra parte, la aplicación practica de las leyes de frecuencia estacionales requiere interpretar correctamente el concepto de periodo de retorno para el caso estacional. Se propone un criterio para determinar los periodos de retorno estacionales de forma coherente con el periodo de retorno anual y con una distribución adecuada de la probabilidad entre las distintas estaciones. Por último, se expone un procedimiento para el cálculo de los caudales estacionales, ilustrándolo mediante su aplicación a un caso de estudio. The compare and develop of a methodology in order to improve the extreme flow estimation for dam hydrologic security has been developed. First, the work has been focused on the adjustment of maximum peak flows distribution functions from which to extrapolate values for high return periods. This has become a major issue as the adoption of stricter standards on dam hydrologic security involves estimation of high design return periods which entails great uncertainty. Accordingly, it is important to incorporate all available techniques for the estimation of design peak flows in order to reduce this uncertainty. Selection of the statistical model (distribution function and adjustment method) is also important since its ability to describe the sample and to make solid predictions for high return periods quantiles must be guaranteed. In order to provide practical application of previous methodologies, studies have been developed on a national scale with the aim of determining a regionalization scheme which features best results in terms of annual maximum peak flows for hydrologic characteristics of Spanish basins taking into account the length of available data. Applied methodology starts with the delimitation of regions taking into account basin’s physiographic and climatic characteristics and the variability of their statistical properties, and continues with their homogeneity testing. Then, a statistical model for maximum annual peak flows is selected with the best behaviour for the different regions in peninsular Spain in terms of describing sample data and making solid predictions for high return periods. This selection has been based, among others, on synthetic data series generation using Monte Carlo simulations and statistical analysis of results from distribution functions adjustment following different hypothesis. Secondly, the work has been focused on the analysis of the relationship between peak flow and volume and how to define design flood hydrographs based on this relationship which can be highly important for large volume reservoirs. However, commonly used hydrologic procedures do not take statistical dependence between these variables into account. A simple and sound method for statistical dependence characterization has been developed by the representation of a joint distribution function of maximum peak flow and volume which is based on marginal distribution function of peak flow and conditional distribution function of volume for a given peak flow. The last one is determined by a regional adjustment procedure of a log-normal distribution function. Practical application is proposed by a probabilistic estimation procedure based on stochastic generation of a large number of hydrographs. The use of this procedure for dam hydrologic security requires a proper interpretation of the return period concept applied to bivariate hydrologic data. A standard is proposed in which it is understood as the inverse of the probability of exceeding a determined reservoir level. When relating return period and hydrological variables the only design flood hydrograph changes into a family of hydrographs which generate the same maximum reservoir level and that are represented by a curve in the peak flow-volume two-dimensional space. This family of design flood hydrographs depends on the dam characteristics as for example reservoir volume or spillway length. Two study cases illustrate the application of the developed methodology. Finally, the work has been focused on the calculation of seasonal floods which are essential when determining the reservoir operation and which can be also fundamental in terms of analysing the hydrologic security of existing reservoirs. However, seasonal flood calculation is complex and nowadays it is not totally clear. Calculation procedures commonly used may present certain problems. Statistical partial duration series, or peaks over threshold method, can be an alternative approach for their calculation that allow to solve problems encountered when the same type of event is responsible of floods in different seasons. A study has been developed to verify the hypothesis of statistical homogeneity of peak flows for different seasons in Spain. Appropriate seasonal periods have been analyzed which is highly relevant to guarantee correct results. In addition, a simple procedure has been defined to determine data selection threshold on a way that ensures its independency which is one of the main difficulties in practical application of partial series. Moreover, practical application of seasonal frequency laws requires a correct interpretation of the concept of seasonal return period. A standard is proposed in order to determine seasonal return periods coherently with the annual return period and with an adequate seasonal probability distribution. Finally a methodology is proposed to calculate seasonal peak flows. A study case illustrates the application of the proposed methodology.

Intimate partner violence among women in Spain: the impact of regional-level male unemployment and income inequality

Background: Intimate partner violence (IPV) against women is a complex worldwide public health problem. There is scarce research on the independent effect on IPV exerted by structural factors such as labour and economic policies, economic inequalities and gender inequality. Objective: To analyse the association, in Spain, between contextual variables of regional unemployment and income inequality and individual women’s likelihood of IPV, independently of the women’s characteristics. Method: We conducted multilevel logistic regression to analyse cross-sectional data from the 2011 Spanish Macrosurvey of Gender-based Violence which included 7898 adult women. The first level of analyses was the individual women’ characteristics and the second level was the region of residence. Results: Of the survey participants, 12.2% reported lifetime IPV. The region of residence accounted for 3.5% of the total variability in IPV prevalence. We determined a direct association between regional male long-term unemployment and IPV likelihood (P = 0.007) and between the Gini Index for the regional income inequality and IPV likelihood (P < 0.001). Women residing in a region with higher gender-based income discrimination are at a lower likelihood of IPV than those residing in a region with low gender-based income discrimination (odds ratio = 0.64, 95% confidence intervals: 0.55–0.75). Conclusions: Growing regional unemployment rates and income inequalities increase women’s likelihood of IPV. In times of economic downturn, like the current one in Spain, this association may translate into an increase in women’s vulnerability to IPV.

Geopolitical shifts in the Eastern Mediterranean. Security Policy Brief No. 43, February 2013

Three major geopolitical events are putting the stability of the Eastern Mediterranean at risk. Most of the region is in a deep monetary and economic crisis. The Arab Spring is causing turmoil in the Levant and the Maghreb. Gas and oil discoveries, if not well managed, could further destabilise the region. At the same time, Russia and Turkey are staging a comeback. In the face of these challenges, the EU approaches the Greek sovereign debt crisis nearly exclusively from a financial and economic viewpoint. This brief argues that the EU has to develop a comprehensive strategy for the region, complementing its existing multilateral regional framework with bilateral agreements in order to secure its interests in the Eastern Mediterranean.

Survey on Rules on Loss of Nationality in International Treaties and Case Law. CEPS Paper in Liberty and Security in Europe No. 57, 30 August 2013

This paper offers a picture of the obligations existing under international and European law in respect of the loss of nationality. It describes international instruments including obligations in this field with direct relevancy for the loss of nationality of Member States of the European Union, but also obligations regarding loss of nationality in regional non-European treaties. Attention is given to two important judicial decisions of the European Court of Justice (Janko Rottmann) and the European Court of Human Rights (Genovese v Malta) regarding nationality. Special attention is devoted to Article 15 of the Universal Declaration of Human Rights, which forbids the arbitrary deprivation of nationality. A survey is provided of possible sub-principles that can be derived from this rule. Finally, some observations are made on the burden of proof in cases of loss of nationality.

Current Challenges regarding the International Refugee Law, with focus on EU Policies and EU Co-operation with UNHCR. CEPS Paper on Liberty and Security in Europe No. 59, September 2013

From an examination of the instruments of the Common European Asylum System (CEAS) and related policy measures regarding border surveillance and migration management, two interrelated issues stand out as particularly sensitive: Access to asylum and responsibility for refugee protection. The prevailing view, supported by UNHCR and others, is that responsibility for the care of asylum seekers and the determination of their claims falls on the state within whose jurisdiction the claim is made. However, the possibility to shift that responsibility to another state through inter-state cooperation or unilateral mechanisms undertaken territorially as well as abroad has been a matter of great interest to EU Member States and institutions. Initiatives adopted so far challenge the prevailing view and have the potential to undermine compliance with international refugee and human rights law. This note reviews EU action in the field by reference to the relevant legal standards and best practices developed by UNHCR, focusing on the specific problems of climate refugees and access to international protection, evaluating the inconsistencies between the internal and external dimension of asylum policy. Some recommendations for the European Parliament are formulated at the end, including on action in relation to readmission agreements, Frontex engagement rules in maritime operations, Regional Protection Programmes, and resettlement.

The Arab Spring: A Litmus Test for the EU’s Women’s Rights Policy in the Euro-Mediterranean Area? Bruges Regional Integration & Global Governance Paper 1/2013

The promotion of women’s rights is described as a priority within the external action of the European Union (EU). As a result of the Arab Spring uprisings which have been ongoing since 2011, democracy and human rights have been pushed to the forefront of European policy towards the Euro-Mediterranean region. The EU could capitalise on these transformations to help positively reshape gender relations or it could fail to adapt. Thus, the Arab Spring can be seen to serve as a litmus test for the EU’s women’s rights policy. This paper examines how and to what extent the EU diffuses women’s rights in this region, by using Ian Manners’ ‘Normative Power Europe’ as the conceptual framework. It argues that while the EU tries to behave as a normative force for women’s empowerment by way of ‘informational diffusion’, ‘transference’ ‘procedural diffusion’ and ‘overt diffusion’; its efforts could, and should, be strengthened. There are reservations over the EU’s credibility, choice of engagement and its commitment in the face of security and ideological concerns. Moreover, it seems that the EU focuses more intently on women’s political rights than on their social and economic freedoms.

The EU’s comprehensive approach towards security: the Lisbon Treaty and “smart power”. EU Centre Singpore Policy Brief No. 6, May 2013

The European Union (EU) has increasingly become a comprehensive security actor. With the development of the Common Foreign and Security Policy (CFSP), including the Common Security and Defence Policy (CSDP) as a reaction to the failure of the EU to act during the wars in Yugoslavia/Western Balkans in the 1990s, the EU has a wide range of instruments for crisis prevention, crisis management as well as post-crisis intervention at its disposal. Observers typically agree that “hard power” is no longer sufficient to address the complex security challenges of today’s world while the EU, often criticised for only utilising “soft power”, is now able to exercise “smart power”. Through a comprehensive approach, facilitated by the Lisbon Treaty, the EU can now use the various instruments at its disposal, such as diplomacy, development aid, humanitarian assistance, trade, sanctions, international cooperation and crisis management capabilities in a joined-up manner. This mix of tools and instruments is helping the EU to achieve the aim set out in its European Security Strategy: “a secure Europe in a better world”.

Exploring a Regional Approach to EU Energy Policies. CEPS Special Report No. 84, 15 April 2014

Regional approaches to EU energy policies have been termed the ‘Schengenisation’ of energy, making reference to the Schengen Convention eliminating intra-European border controls. They aim to hone the effectiveness of EU energy policy objectives through enhanced policy coordination at the regional scale. Typically, this includes energy market integration while accounting for member states’ continued deployment of national-level policy instruments regarding the appropriate energy mix and the security of energy supply, which is foreseen in the EU Treaty. This report explores the potential for such regional approaches. It assesses lessons from existing initiatives, regional energy arrangements such as the Danube Energy Forum, the Mediterranean Energy Forum, the Pentalateral Energy Forum, the North Seas Countries’ Offshore Grid Initiative and the Nordic Co-operation partnership, to determine whether regional energy initiatives are an efficient, effective and politically acceptable approach toward reaching three EU energy policy objectives: competitiveness, supply security and sustainability. Regional approaches could possibly play an important role for governing EU renewables policy, which the European Commission has identified in the 2030 climate and energy framework as an important element for governance.

L'Union européenne face aux BRICS dans la gouvernance mondiale: Une réponse efficace? = The European Union facing the BRICS countries in world governance: an effective response? Bruges Regional Integration & Global Governance Paper 2/2014

Le présent travail se concentre sur deux principaux acteurs du monde en évolution, l'Union européenne (UE) et l'ensemble des pays BRICS, et le défi que posent collectivement ces derniers à la première sur la base de leurs poids économique et politique accrus dans le cadre de la gouvernance mondiale. On fait valoir que la doctrine d’un « multilatéralisme efficace » décrivant la position de l’UE sur la gouvernance mondiale est de plus en plus remise en cause par les BRICS dont l’approche repose sur un autre principe : celui d’un « multilatéralisme relationnel ». Afin de pouvoir analyser comment l’UE réagit à la confiance et la cohérence croissante des BRICS dans les instances internationales, ce travail examine la réponse de l’UE dans trois domaines de la gouvernance mondiale que sont le commerce, le changement climatique et la sécurité internationale. Ceci permet d’évaluer dans quelle mesure les différentes institutions européennes mettent en œuvre ce que ce travail qualifie de « réponse efficace » à la montée en puissance des BRICS. Au terme de l’analyse, cette étude s’attache à souligner que la réaction des institutions de l’UE à l'influence grandissante des BRICS sur la scène internationale ne peut être considérée comme efficace que dans le domaine du changement climatique.

Trading off sovereignty. The outcome of Belarus's integration with Russia in the security and defence field. OSW Commentary No. 107, 2013-04-25

Although the Republic of Belarus is constitutionally designated as a neutral country1, it is in fact closely connected with Russia’s own security and defence architecture. Within the Union State of Belarus and Russia, the armed forces are integrated to an extent unequalled in the world. A legacy of the Soviet division of labour, the Belarusian defence industry complex remains structurally dependent on Russia, which is its main raw material provider, outlet for exports and intermediary on world markets. Bilateral military cooperation also builds on the perception of common threats and partly shared security interests. Hence it unfolds regardless of the disputes that sporadically sour relations between Minsk and Moscow, standing out as the main achievement of the Union State – if not the only one.

Conflicting Role Conceptions: In Search of the European Union's Added Value for its Southern Neighbors. Bruges Regional Integration & Global Governance Paper 04/2014

Many scholars have analyzed the role of the European Union (EU) in its southern neighborhood by looking at the EU’s policy documents and strategies. As such, it is often argued that the EU is at best a useful partner in democratic reform and at worst an unsuccessful ‘normative power’. However, very few studies have analyzed the EU’s role from the recipients’ point of view: the southern neighboring countries themselves. This paper adopts an ‘outside-in approach’ and explores what the southern neighborhood countries believe the EU should be or do. On the basis of a set of 15 interviews with diplomats from the region and an analysis of 50 newspaper articles from the region on the EU’s relations with its southern neighborhood, this paper seeks to reveal the EU’s real ’added value’ for its southern Mediterranean partners. To what extent does the EU’s own perceived role in its southern neighborhood match the role conception of those countries? Based on the three case studies of Algeria, Jordan and Egypt, the paper finds that there is a clear divergence in role conceptions between the EU and its southern partners. While the EU sees itself as a ‘force for good’ and promoter of norms and democracy in the southern Mediterranean region, the three countries primarily believe that the EU perceives itself foremost as a provider of security and stability in the region, while they primarily expect it to act as a reliable partner for economic cooperation.

RED vs. REDD: Biofuel Policy vs. Forest Conservation. Factor Markets Working Document No. 41, May 2013

This paper assesses the complex interplay between global Renewable Energy Directives (RED) and the United Nations programme to Reduce Emissions from Deforestation and forest Degradation (REDD). We examine the interaction of the two policies using a scenario approach with a recursive-dynamic global Computable General Equilibrium model. The consequences of a global biofuel directive on worldwide land use, agricultural production, international trade flows, food prices and food security out to 2030 are evaluated with and without a strict global REDD policy. We address a key methodological challenge of how to model the supply of land in the face of restrictions over its availability, as arises under the REDD policy. The paper introduces a flexible land supply function, which allows for large changes in the total potential land availability for agriculture. Our results show that whilst both RED and REDD are designed to reduce emissions, they have opposing impacts on land use. RED policies are found to extend land use whereas the REDD policy leads to an overall reduction in land use and intensification of agriculture. Strict REDD policies to protect forest and woodland lead to higher land prices in all regions. World food prices are slightly higher overall with some significant regional increases, notably in Southern Africa and Indonesia, leading to reductions in food security in these countries. This said, real food prices in 2030 are still lower than the 2010 level, even with the RED and REDD policies in place. Overall this suggests that RED and REDD are feasible from a worldwide perspective, although the results show that there are some regional problems that need to be resolved. The results show that countries directly affected by forest and woodland protection would be the most economically vulnerable when the REDD policy is implemented. The introduction of REDD policies reduces global trade in agricultural products and moves some developing countries to a net importing position for agricultural products. This suggests that the protection of forests and woodlands in these regions reverses their comparative advantage as they move from being land-abundant to land-scarce regions. The full REDD policy setting, however, foresees providing compensation to these countries to cover their economic losses.
