The Port Authority of Bilbao, the Maritime Engineering Laboratory (LIM) of the UPC and AZTI, are developing a project, co-financed by the OCYT and FEDER funds, aiming to provide the Port of Bilbao with a numerical forecasting tool of marine pollution due to spillage accidents of hydrocarbons. The system to be developed will simulate, initially, the hydrodynamic conditions in the estuary. Therefore, the three-dimensional algorithms for the resolution of the shallow-water equations, developed jointly by LIM and AZTI, will be applied. These algorithms take into account the most relevant oceanographic processes in the region: wind, tide and density gradients. The next step in the project is the adaptation of a numerical code for the resolution of the general convection-diffusion equation, applied to the dispersion of hydrocarbons in the sea. The set of numerical codes used will be calibrated with data collected by different apparatus moored in the problem area and with data of drifting buoy experiments. In a similar way, all available information relating to the topography/bathymetry, wind regimes, precipitation and river discharges, tides, CTD profiles, etc. will be collected and incorporated within the modelling process. The system will be available to the Port Authority of Bilbao and will be designed to be used on a PC platform, in a visual and user-friendly environment.

Se produce, en principio, la pérdida de superficie de las playas,situación que erosiona gradualmente los acantilados subyacentes. Esto es consecuencia de la acción combinada del oleaje en tormentas, del ascenso de los niveles del mar por causas meteorológicas, y de la intervención humana. A partir de un estudio histórico, se ha determinado que las playas en cuestión han sufrido fuertes procesos erosivos en los últimos 50 años debido a: (i)extracciones de arena para la construcción; (ii)fuertes tormentas desde el cuadrante SE; (iii) la fijación de dunas y pérdida del material de reserva natural de la playa; (iv)las urbanizaciones costeras y construcción de espigones transversales a la costa que interrumpen parcialmente el transporte litoral(por ejemplo del puerto Quequén 100 Km al sur); (v) los d...

En este trabajo se analiza la crecida del Río Pilcomayo entre el 29 de enero y el 7 de febrero del año 2014 y sus desbordes en el tramo entre Villamontes y Misión La Paz con el apoyo en productos satelitales, aforos y lectura de niveles disponibles. También se aplica un modelo hidráulico unidimensional con HEC-RAS para aproximar el hidrograma de desbordes. El análisis aquí presentado permitió evaluar la recurrencia del evento para Misión La Paz, estimada en 1.1 años, el volumen desbordado que asciende a los 72 hm3 , así como la velocidad de avance del frente de la crecida estimado en 6.80 km/día en 14 horas de desborde. También se estudia las superficies de las áreas inundadas y movimiento del lecho antes y después del paso de la crecida en las secciones de aforo.The Pilcomayo River flood events and overflows are ...

Los modelos numéricos de simulación de la realidad física permiten una aproximación novedosa al estudio de los impactos causados por las explotaciones de piscicultura, facilitando el análisis de las alternativas de ubicación y optimizando los recursos necesarios para los planes de vigilancia de las explotaciones.

Para lograr este objetivo se realizó una modelación numérica bidimensional permanente a fondo fijo y sin transporte de sedimentos de la hidráulica del tramo. La zona de estudio se localiza en la zona que se conoce como Pilcomayo Superior, parte de la cuenca baja del río Pilcomayo, 13 km al noroeste de la localidad Santa Victoria en la provincia de Salta Argentina. Para realizar la modelación se han analizado imágenes satelitales, hidrogramas, aforos durante crecidas, topografías e imágenes de radar SRTM. En una primera etapa se analizó la topografía e imágenes SRTM para elaborar el modelo digital del terreno, posteriormente se seleccionaron las condiciones de contorno del modelo con la ayuda de imágenes satelitales y series hidrométricas, y finalmente se evaluaron los resultados de las simulaciones numéricas para determinar los caudales que desbordan y los que continúan aguas abaj...

The breakwater was designed by the Hydraulics Laboratory of the National University of Cordoba (UNC, Spanish acronym), Argentina to protect a portion of the Mar del Plata coast. The study was financed by SeCyT-UNC research projects and the Cordoba Ministry of Science and Technology. The main objective of this study was to experimentally verify the stability of the structure when exposed to design conditions. To that end, experiences described in the literature and all available information were gathered to develop a methodology that could be applied to a majority of the laboratory tests using the same characteristics of those presented in this study. The tests were performed with a 23 m long, 0.5 m wide and 0.9 m high channel using a twodimensional wave generator with front paddles (HR-Wallingford). The waves were measured with 8 resistance wave gauges. The modelling required adapting the available facilities by adjusting the base in order to reach the breaking conditions of the design wave and determine the correct placement of the structure. The tests represented extreme wave conditions similar to those measured in the Mar del Plata over 50 years. The breakwater contained pieces of 5 Tn, water levels ranged from high to low tides and a scale of 1:30 was selected.

This beach is part of La Concha bay, with Santa Clara Island in the middle of the bay and a semi submerged dike and reef in front of it. The combination of this morphology together with the tidal range in the area (max. springs 4.6m) results in a very particular wave climate. The beach contains different strata of sand, natural rocks and the remains of artificial structures. Therefore, rocks sometimes appear at the surface, depending on the changes of the beach profile. This situation harms the normal use of the beach and can be a risk for the users. During recent years this process has increased and, especially in the summer, a big part of the intertidal profile of the West part of the beach shows a gravely and rocky profile. In 2003, the town council of San Sebastian entrusted AZTI Foundation with the study of this beach. For this purpose AZTI planned the data analysis and the morphodynamic study of the evolution of the beach in three different time scales, in order to clarify whether the recent problems at the beach are an increasing erosive process, or part of a natural cycle. The three different time scales of analysis of morphodynamic processes taking place in this beach are:-Short term scale: wave data measurement and analysis, modeling of wave, current and sediment transport.-Medium term scale: analysis of seasonal equilibrium shape and profile.-Long term scale: analysis of morphodynamic evolution of the whole system (the bay). This analysis has contributed to the management of the beach, implying artificial seasonal sand movements, trying to encompass the natural processes and shoreline protection with the recreational use of the beach.

Different alternatives of the layout scheme of the channel, the weirs geometry and turbine alignment have been considered to optimize the design and the hydraulic efficiency of the hydraulic components. Operational flow scenarios have been simulated in order to verify the conditions of weir and intake inflow. Streamlines, eddies generation, flow distribution of the flow have been analyzed to define the best hydraulic operating conditions. The numerical Delft3D model, developed by Deltares, has been used. The hydrodynamic model allows the simulation of unsteady flow in three dimensions. The numerical solution scheme is finite difference, using curvilinear coordinates and vertical . It also allows the generation of a computational domain with different degrees of mesh refinement. As a result of the study, improvemen...

This article presents a stationary two-dimensional model with fixed bed and no sediment transport in the overflow reach of El Chañaral and La Garrapata, located in the Upper Pilcomayo, part of the lower basin of the Pilcomayo River, in order to approximate the flow that activates the overflows. To achieve the proposed objective it has been analyzed satellite imagery, hydrographs, gauging during floods, topographies and SRTM radar images. In a first stage the topography and images SRTM were analyzed to develop the digital terrain model, then the boundary conditions model were selected with the help of satellite images and hydrometric series, and finally the results are evaluated to determine flow rates that overflows as well as those which continue downstream in the Pilcomayo River. Subsequently the results of the modeling are superimposed on satellite images available for the st...
