Direct estimation wave setup as a medium level in swash

The extreme runup is a key parameter for a shore risk analysis in which the accurate and quantitative estimation of the upper limit reached by waves is essential. Runup can be better approximated by splitting the setup and swash semi-amplitude contributions. In an experimental study recording setup becomes difficult due to infragravity motions within the surf zone, hence, it would be desirable to measure the setup with available methodologies and devices. In this research, an analysis is made of evaluated the convenience of direct estimation setup as the medium level in the swash zone for experimental runup analysis through a physical model. A physical mobile bed model was setup in a wave flume at the Laboratory for Maritime Experimentation of CEDEX. The wave flume is 36 metres long, 6.5 metres wide and 1.3 metres high. The physical model was designed to cover a reasonable range of parameters, three different slopes (1/50, 1/30 and 1/20), two sand grain sizes (D50 = 0.12 mm and 0.70 mm) and a range for the Iribarren number in deep water (ξ0) from 0.1 to 0.6. Best formulations were chosen for estimating a theoretical setup in the physical model application. Once theoretical setup had been obtained, a comparison was made with an estimation of the setup directly as a medium level of the oscillation in swash usually considered in extreme runup analyses. A good correlation was noted between both theoretical and time-averaging setup and a relation is proposed. Extreme runup is analysed through the sum of setup and semi-amplitude of swash. An equation is proposed that could be applied in strong foreshore slope-dependent reflective beaches.

Uncertainties in the design of support structures and foundations for offshore wind turbines

Offshore wind industry has exponentially grown in the last years. Despite this growth, there are still many uncertainties in this field. This paper analyzes some current uncertainties in the offshore wind market, with the aim of going one step further in the development of this sector. To do this, some already identified uncertainties compromising offshore wind farm structural design have been identified and described in the paper. Examples of these identified uncertainties are the design of the transition piece and the difficulties for the soil properties characterization. Furthermore, this paper deals with other uncertainties not identified yet due to the limited experience in the sector. To do that, current and most used offshore wind standards and recommendations related to the design of foundation and support structures (IEC 61400-1, 2005; IEC 61400-3, 2009; DNV-OS-J101, Design of Offshore Wind Turbine, 2013 and Rules and Guidelines Germanischer Lloyd, WindEnergie, 2005) have been analyzed. These new identified uncertainties are related to the lifetime and return period, loads combination, scour phenomenon and its protection, Morison e Froude Krilov and diffraction regimes, wave theory, different scale and liquefaction. In fact, there are a lot of improvements to make in this field. Some of them are mentioned in this paper, but the future experience in the matter will make it possible to detect more issues to be solved and improved.

Storm characterization for analyzing stone armour damage progression

Storm evolution is fundamental for analysing the damage progression of the different failure modes and establishing suitable protocols for maintaining and optimally sizing structures. However, this aspect has hardly been studied and practically the whole of the studies dealing with the subject adopt the Equivalent triangle storm. As against this approach, two new ones are proposed. The first is the Equivalent Triangle Magnitude Storm model (ETMS), whose base, the triangular storm duration, D, is established such that its magnitude (area describing the storm history above the reference threshold level which sets the storm condition),HT, equals the real storm magnitude. The other is the Equivalent Triangle Number of Waves Storm (ETNWS), where the base is referred in terms of the real storm's number of waves,Nz. Three approaches are used for estimating the mean period, Tm, associated to each of the sea states defining the storm evolution, which is necessary to determine the full energy flux withstood by the structure in the course of the extreme event. Two are based on the Jonswap spectrum representativity and the other uses the bivariate Gumbel copula (Hs, Tm), resulting from adjusting the storm peaks. The representativity of the approaches proposed and those defined in specialised literature are analysed by comparing the main armour layer's progressive loss of hydraulic stability caused by real storms and that relating to theoretical ones. An empirical maximum energy flux model is used for this purpose. The agreement between the empirical and theoretical results demonstrates that the representativity of the different approaches depends on the storm characteristics and point towards a need to investigate other geometrical shapes to characterise the storm evolution associated with sea states heavily influenced by swell wave components.

Diseño de protecciones para el control de la socavación en parques eólicos marinos

La presente investigación se basa en el análisis de los diferentes criterios empleados hasta la fecha para el dimensionamiento de las protecciones frente a la socavación presentes en parques eólicos marinos monopilotados. A través de la revisión que se realizó sobre las recomendaciones de diseño existentes se detectó una gran carencia de criterios basados en parámetros característicos del oleaje. En este sentido, considerando la importancia que las acciones del oleaje tienen tanto en el desarrollo del fenómeno de la socavación alrededor de las cimentaciones, como en su propio diseño, se propone el empleo de un nuevo criterio basado en variables caracteristicas del oleaje, y la clasificación de dichas estructuras de acuerdo a la propuesta que Van der Meer realizó en su tesis (Van der Meer, 1988).

Las "Provincias Bascongadas" del Atlas Geográfico de España de Tomás López de 1804.

La obra cartográfica de Tomás López siempre despertó controversias y no le han faltado detractores que señalan la falta de exactitud de sus mapas. Aun así la obra de Tomás López tiene un gran reconocimiento por su carácter compilatorio de toda la información cartográfica disponible en hasta la época. En general es poco conocido el vínculo entre la obra de López con el ?laboriosísimo desarrollo? de los mapas de Polo y Catalina, que se responsabilizó de la organización de la información para el Censo de la riqueza territorial e industrial de España (1803). Para ello, planimetró por el método de los triángulos uno a uno los mapas de la serie de reinos y provincias peninsulares y las islas del Atlas Geográfico de España (AGE) de Tomás López de 1804. En este trabajo se muestra un ejemplo de la precisión del AGE y alto grado de correlación de toponímico con la cartografía actual en las tres ?Provincias Bascongadas? que comprendían el ?Señorío de Vizcaya?, la ?Provincia de Guipuzcua? y la ?Provincia de Alava?.
