This paper presents a study of the upwelling of tropical cyclones Iván (2004) and Gustav (2008), both associated with coastal flooding in the area. The Delft3D-FLOW model was applied in order to determine its influence on the total sea surges that occurred. Graphs of sea elevation due to upwelling were obtained at La Coloma, Playa Bailen, Cabo de San Antonio, Playa Bibijagua and Carapachibey. In the absence of measured data, it was validated by comparing the results with previous studies and modeling in another area, with the presence of sea level measurement stations, but applying the same methodology. Finally, it was concluded that the application of the model under the methodology used correctly described the phenomenon. [ABSTRACT FROM AUTHOR]

The Varadero beach is a tourism place one of the most famous in Cuba. For the Oasis sector has been design and artificial beach compose for several submerged breakwater parallel to the coast, and an initial sand supply project. It this paper is presented the evaluation of the project applying a train of numerical model coupling ADCIRC + SWAN + Xbeach. It was analyzed the hydrodynamics and wave variables. The morphological behavior of the initial nourishment was evaluated. The results of the study show the proposal is not effective, the losses of sand and the reshape of the beach for climate condition studied do not meet the tourism demands. [ABSTRACT FROM AUTHOR]

To simulate coastal process, due to their complexity, the required precision and the desired results, it becomes necessary the use of several mathematical models coupled to each other. In this work an attempt is made for an optimum coupling of two wave generation and wave propagation models (WW3 v3.14 and SWAN v40.85), for which two work phases are established. The first phase has as its fundamental objective to determine the best relationship between precision and computational time, while the second is mainly directed to obtain the best nesting alternative between the models. The case study to carry out the investigation was the Wilma hurricane. The statistical variable to determine the best results was the coefficient of determination R². [ABSTRACT FROM AUTHOR]

Behaviour of wave, current and sediment transport in coastal sector of "La Guardia -- La Restinga" was analysed in former papers. In this coastal sector an accelerated erosion of the beach is being produced. In order to mitigate it, a group of coastal actions have been indicated taking into account the requirements of Ministerio del Ambiente for this land. Modifications in coastal dynamics as a consequence of these works are described in this paper. [ABSTRACT FROM AUTHOR]

In the coastal sector of "La Guardia -- La Restinga", an accelerated erosion of the beach is produced. In order to mitigate it, a study about wave, current and sediment transport for calm and extreme conditions is done, take into account the data set from Venezuelan environmental authorities.

In the coastal sector of "La Guardia -- La Restinga" an accelerated erosion of the beach is ocurring due to meteorological events and anthropic works. This produces damage to the social and economical situation of the zone. To obtain a solution to this problem a set of engineering works has been proposed which require gathering numerous data. These data are shown and related in the present work. [ABSTRACT FROM AUTHOR]

This work is a diagnose study of problems presented in some coastal areas of the Bolivarian Republic of Venezuela. Each visited place has been briefly described, showing main problems, its causes and recommended measures. Secondly, selection criteria have been established to determine execution priorities in each state of the country. [ABSTRACT FROM AUTHOR]

It is well known that artificial regeneration such as sand dumping represents one of the ways for sedimentary enrichment and temporal stability of beaches, conducive to environmental protection and sustainable development. Because in Varadero there have been always problems with erosion in certain parts of its northern coast, it was decided in this work to make a detailed study of these areas in order to pose a possible solution. A number of objectives have been stated to get an answer to the issues raised. The main objective is the implementation of the "Coastal Modeling System" (SMC) for the study of an alternative and in turn solving the erosion problem. [ABSTRACT FROM AUTHOR]

High intensity hurricanes attack frequently the Cuban island with great damages and high costs in the evacuation of people living in vulnerable areas. This paper presents an analysis of hurricanes that have affected the region to assist in the design and construction of solutions to prevent strong sea penetrations, by means of the SWAN mathematical model. Precedent studies have shown that a simple relationship between hurricane intensity and wave heights associated to it does not exist for a given point in the coastline. The paper shows the results of an investigation applying the SWAN model, developed by the Technological University of Delft. It is applied in its non stationary form to simulate the most unfavorable possible trajectories in the study region. [ABSTRACT FROM AUTHOR]

The result of studies in physical models is presented to develop a deterministic mathematical model to estimate the rate of average overtopping due to storm waves in coastal defense dikes of mixed type. [ABSTRACT FROM AUTHOR]
