Análisis de la técnica de recarga artificial en la Cubeta de Sant Andreu de la Barca (Barcelona)

El presente proyecto pretende mostrar las posibilidades de la recarga artificial como elemento de gestión de los recursos de agua subterránea del acuífero aluvial del río Llobregat, en su sector de la Cubeta de Sant Andreu de la Barca (Barcelona), el cual es fuente de abastecimiento urbano, agrícola e industrial del entorno de Sant Andreu de la Barca. Igualmente, se revisa la efectividad de la aplicación de dicha técnica que se practica actualmente. Hace años, las condiciones naturales del río hacían posible la recarga natural de la Cubeta, pero la implantación de industrias en la zona y la regulación mediante la presa de La Baells desde el año 1976, han originado cambios en el comportamiento natural del acuífero, que se han manifestado básicamente en una disminución de la recarga natural como consecuencia de la impermeabilización de los suelos originada por la urbanización de los mismos. Se ha producido también un fenómeno de colmatación del lecho del río, al dificultarse la removilización de los materiales finos depositados en el fondo del cauce, produciendo también una disminución de la recarga al acuífero a través del lecho. Por último, la mayor demanda de suministro por parte del sector industrial ha influido negativamente en el almacenamiento del acuífero. Desde hace décadas, se lleva efectuando una recarga artificial en el lecho del río para tratar de paliar en lo posible estos efectos perjudiciales. La misma se efectúa mediante dos sistemas distintos: escarificando el lecho del río para aumentar su capacidad de infiltración, y mediante la utilización de balsas de recarga, a través de las cuales se infiltra el agua en el acuífero. El objetivo de este proyecto es analizar el efecto actual que la recarga mediante balsas está teniendo sobre el acuífero. Para ello, se utilizarán, entre otras técnicas, la elaboración de un modelo matemático con el que poder simular el efecto de la recarga. VIII ABSTRACT This project aims to show the possibilities of artificial recharge as groundwater resources management element in the alluvial aquifer of the Llobregat River, in the sector of the Basin of Sant Andreu de la Barca (Barcelona), which is a source of urban, agricultural and industrial supply of the Sant Andreu de la Barca area. Too, the effectiveness of the current implementation of this technique is reviewed. Years ago, natural river conditions made possible the natural recharge of the aquifer, but the establishment of industries in the area and the river regulation by the la Baells dam since 1976, have led to changes in the natural behavior of the aquifer, which basically are a decrease in natural recharge, because the soil has become impervious, due to land urbanization. There has been also a phenomenon of clogging of the river bed, caused by the difficult in the remobilization of fine materials deposited on the river bed, which has produced a decrease in the groundwater recharge through the river. Finally, the increase in water demand by the industrial sector, has diminished aquifer storage. For decades, artificial recharge in the river bed has been practiced to alleviate negative effects. It is done by two different systems: scratching the river bed to increase its infiltration capacity, and using recharge ponds, through which water infiltrates into the aquifer. The objective of this project is to analyze the current effect that recharge by ponds is having in the aquifer. Among other techniques, mathematical modeling has been used for simulating the effect of artificial recharge in the aquifer.

Does high speed rail compete fairly with other transportation modes? Madrid-Barcelona case study

Transportation modes produce many external costs such as congestion, accidents, and environmental impacts (pollution, noise and so on). From the microeconomic theory it is well known that in order to maximize social welfare, transportation modes should internalize the marginal costs they produce. Allocative efficiency is achieved when all transportation modes are priced at their social marginal cost. The objective of this research is to evaluate to what extent different passenger transport modes internalize their social marginal costs. This analysis is important since it affects the competitiveness of the different transport modes for a given OD pair. The case study analyzed is the corridor Madrid-Barcelona in Spain and the different transport modes have been considered (cars, buses, high-speed train and air). The research calculates the marginal social cost per user for each transportation mode, and it compares it with the average fare—allowing for the effect of discriminatory taxes—currently paid by the users. The external costs are calculated according to the guidelines established by the European Union. The gap between the marginal social cost and the price paid by users will provide the extra cost per passenger that each transport mode should have to pay for internalizing the external cost it produces. The research shows that external costs already produced by road and air transport modes are much higher than those produced by rail. However, the results show that road transport already internalizes every external costs it produces because users pay high fuel taxes. In other words, although rail transportation produces lower external costs, road transportation pays more than it should on the basis of the social marginal costs. The results of this work might be of help for Europ ean policy actions to be undertaken in the future.

Crossed-arch vaults in late-gothic and early Renaissance vaulting: a problem in building technology transfer

Crossed-arch vaults are a particular type of ribbed vaults. Their main feature is that the ribs that form the vault are intertwined, forming polygons or stars and leaving an empty space in the middle. The firsts appear in Córdoba in the second half of the 10th Century. Afterwards, the type diffused through Spain and North Africa, 11th_13th Centuries. These vaults reappear in Armenia in the 13th Century. In the 14th and 15th Century a few examples are found both in England (Durham, Raby) and Central Europe (Prague, Landshut, Vienna). At about the same time, Leonardo da Vinci produced designs for the Tiburio (Ciborium) of Milan cathedral with a cross-arched structure and proposed tests to assess the strength; he also, made use of the same pattern of vault for Renaissance centralized churches. Eventually, the type can be tracked through the 17th (Guarini) and 18th (Vittone) Centuries, until Spanish post war architecture in the 1940-60s (Moya). Some questions arose, which so far, have not been answered. How was it possible that a particular type of vault had such enormous geographical spread? How was it transmitted from Córdoba to the Caucasus? The matter is one of transfer of knowledge, ideas, and technology; it relates both aesthetics and construction.

Contribution to Load-Frequency Regulation of a Hydropower Plant with Long Tail-Race Tunnel

In this paper, a hydroelectric power plant with long tail-race tunnel has been modelled for assessing its contribution to secondary regulation reserve. Cavitation problems, caused by the discharge conduit length, are expected downstream the turbine where low pressure appears during regulation manoeuvres. Therefore, governor's gains should be selected taking into account these phenomena. On the other hand, regulation services bidden by the plant operator should fulfil TSO (Transmission System Operator) quality requirements. A methodology for tuning governor PI gains is proposed and applied to a Hydro power plant in pre-design phase in northwest area of Spain. The PI gains adjustment proposed provides a proper plant response, according to some established indexes, while avoiding cavitation phenomena.

Prospects and challenges of a Pan-European post-trade infrastructure. ECMI Policy Brief No. 20, 8 November 2012

After more than a decade of indecision, the EU is finally now set to implement a consistent regulatory architecture for clearing and settlement. Following the agreement on a European market infrastructure Regulation (EMIR), the European Commission has proposed harmonised rules for centralised settlement depositaries (CSDs), while the European Central Bank is moving forward with its plans for a central eurozone settlement engine. This paper analyses three components of the new post-trade infrastructure measures: 1) the regulatory framework for and supervision of central counterparties under the new EMIR legislation, 2) the authorisation requirements of trade repositories and 3) the draft CSD Regulation and the progress with the ECB’s Target 2 Securities project. It then discusses the impact of the new rules, and argues that, analogous to the unexpected impact of MiFID on trading infrastructures, a similar EMIR revolution may be on its way.

Financial services and the Transatlantic Trade and Investment Partnership. CEPS Policy Brief No. 302, 20 November 2013

Given the size of the financial markets on both sides of the Atlantic and the symmetry in the follow-up of the G-20 standards, Karel Lannoo argues in this Policy Brief that the Transatlantic Trade and Investment Partnership (TTIP) provides a good opportunity to put in place a more institutionalised framework. He finds that both blocs have reacted in similar ways to the financial crisis in strengthening their regulatory and supervisory frameworks and incorporating the G-20 recommendations into federal law. He also notes that consumer protection has been reinforced, certainly in the US, with the creation of the Consumer Financial Protection Bureau. And on the EU side, the Single Supervisory Mechanism (SSM) will radically change banking supervision. In his view, inclusion of financial services could also be an opportunity to strengthen prudential rules and consumer protection provisions on both sides. Rather than leading to a reduction of consumer protection, as had been feared in the post-crisis environment, it could lead to an examination, exchange and recognition of best practices in regulation and enforcement. Finally, he concludes that inclusion of financial services would make it part of the permanent regulatory dialogue that will be established as a result of a successful TTIP.

Can border carbon taxes fit into the global trade regime? Bruegel Policy Brief 2013/06, 9 December 2013

One complement to domestic climate policies could be the regulation of carbon dioxide emissions arising during the production of imported products. Such ‘border carbon adjustments’ (BCAs) are said to have several benefits, but are also severely criticised. This Policy Brief highlights some weaknesses in the standard argumentation for BCAs. But there is an alternative argument for border carbon measures, based on the fact that countries expose each other to climate externalities. The reformulated argument is economically more convincing, and provides a more convincing justification for the extraterritorial feature of border carbon measures. However, there are also several important factors mitigating against the implementation of such measures, including the risk that these measures will be used for protectionism.

GATS and the Social Regulation of Services. IES WORKING PAPER 3/2010

Many service transactions are highly complex, and their quality is difficult to ascertain for consumers. In order to have properly functioning service markets, the services thus often require regulation. However, with the advent of the WTO, international trade in services has become increasingly rule-bound. GATS has considerable, intricate effects on social regulation due to the characteristics of services. The allocation of regulatory jurisdiction between home and host country, for example, is rendered difficult by the process-based nature of a lot of services. The WTO US – Gambling dispute settlement report is the first to address GATS disciplines on social regulation in a detailed manner. This working paper submits that the US - Gambling report has increased interference with domestic social regulation and created regulatory uncertainty for WTO members. However, it is also argued that the real impact of the GATS on social regulation can only be understood by looking beyond the text of the GATS. GATS disciplines may become amplified through their interaction with domestic and other international law. The GATS also contains some “political” counterbalancing mechanisms that allow members to renegotiate their commitments. It is argued that these political mechanisms strengthen subsidiarity in the GATS, and make WTO dispute settlement bodies accountable to WTO members.

The Regulatory Framework of Export Restrictions in WTO Law and Regional Free Trade Agreements. IES WORKING PAPER 8/2013

The use of export restrictions has become more and more common in recent years, evidencing the substantial loopholes existing in the WTO regulation on the matter. As a result of this deficient legal framework, the WTO membership experiences important losses of welfare and increasing political tensions. The multilateral negotiations for an updated discipline on export restrictions, in the context of the Doha Development Round, are blocked. Consequently, members have established a set of preferential bilateral and multilateral agreements to relieve the negative effects of these measures. Likewise, some recent WTO members have committed to stricter regulations as part of their Accession Protocols. Nevertheless, these methods have evidenced some important flaws, and the multilateral scene remains the optimum forum to address export restrictions. This Working Paper proposes a number of measures to improve the legal framework of the quantitative export restrictions and export duties, as well as their notification procedures.

TTIP’s Hard Core: Technical barriers to trade and standards. Paper No. 13 in the CEPS-CTR project ‘TTIP in the Balance’ and CEPS Special Report No. 117/August 2015

Michelle Egan and Jacques Pelkmans provide an overview of the TBT chapter in TTIP and the various issues between the US and the EU in this area, which in turn requires extensive expositions of domestic regulation in the US and the EU. TBTs, outside heavily regulated sectors such as chemicals, automobiles or medicines (which have separate chapters in TTIP), can be caused by divergent (voluntary) standards, technical regulations and conformity assessment. Indeed, in all three the US and the EU have long experienced frictions with considerable trading costs. The 1998 Mutual Recognition Agreement about conformity assessment only succeeded in two out of six sectors. The US and European standardisation traditions differ and this paper explains why it is so hard, also economically, to realise convergence. However, the authors reject the unproductive ‘stand-off’ between US and EU negotiators on standardisation and suggest to clarify the enormous economic ‘installed base’ of prominent US standards in the world economy and build a solution from there. As to technical regulation, the prospect of converging regulation (via harmonisation) is often dim, but equivalence (given similar levels of regulatory protection) can be an option.
