In recent years, modeling has emerged as an invaluable tool for understanding the functioning of coastal lagoons. Modelling the environmental characteristics of the coastal area near the Bay of Bengal, India has received increasing attention from researchers in the past years. This interest has stimulated a scientific investigation of lagoon ecosystems, which have been studied from the physical...

The paper addresses the application of the nonlinear hydrodynamics model (RANS (Reynolds-averaged Navier–Stokes) equations) in a wide semi-enclosed Mediterranean lagoon (Berre lagoon), considering three natural forcing functions, i.e., sea tide propagating through a long narrow channel, wind and runoff. Main attention is focused to characteristic velocities (at free surface and bottom) and to f...

Our research goal is to monitor the water pollution and aquatic plants in the coastal lagoon environments using satellite data. This time, our past activities concerning some satellite study project and the preliminary result of ALOS/AVNIR-2 analysis in coastal lagoon such as Lakes Shinji and Nakaumi are introduced.

In this chapter we define coastal lagoons according the definition proposed by Kjerfve (1994) as “shallow water bodies separated from the ocean by a barrier, connected at least intermittently to the ocean by one or more restricted inlets, and usually oriented shoreparallel”. This definition is given in an introduction chapter of a multiauthor book edited by Kjerfve (1994). Nevertheless, in the ...

The coastal plain of the Rio Grande do Sul state (RS) in southern Brazil, has an enormous lagoon complex in its southern portion formed by Patos Lagoon, Mirim Lagoon, Mangueira Lagoon and several other smaller lakes. This system was originated from successive transgression and regression cycles, which took place since the upper Pleistocene (Vilwoock, 1984). Patos Lagoon is a huge chocked lagoon...

metal contents viz., cu, ni, co, zn and cd in sediment cores recovered from the vembanad lake, the largest estuarine-lagoonal system on the west coast of india, were analysed to understand the pollution levels and the impact on the coastal environment. of the three cores studied, vc-10 shown enrichment in all metals compared to other cores, as it is located in the vicinity of industrial area. f...

coastal lagoons are complex ecosystems exhibiting a high degree of non-linearity in the distribution and exchange of nutrients dissolved in the water column due to their spatio-temporal characteristics. this factor has a direct influence on the concentrations of chlorophyll-a, an indicator of the primary productivity in the water bodies as lakes and lagoons. moreover the seasonal variability in...

The exotic Indo-West-Pacific species, Ficopomatus uschakovi (Polychaeta, Serpulidae) is recorded for the first time in the Tropical Eastern Pacific from two sites in La Encrucijada Biosphere Reserve, Chiapas, a coastal lagoon in the Pacific south of Mexico. The means of dispersal of this serpulid species still remains unclear, as the nearest port (Puerto Chiapas) is 70 km to the south, and ther...

The Sand Motor is a mega-nourishment characterized by a very large sand volume of around 20 million m placed along the Dutch coast. The Sand Motor is a pilot project to evaluate the performance of an alternative nourishment strategy with respect to different functions of the coastal system. Within the scope of the coastal functions, the hook-shaped design of the initial morphology of the Sand M...

in less than 150 words) Negombo Lagoon is one of the most productive and sensitive ecosystems in Sri Lanka. The main fresh water input comes to this lagoon from the rivers Dandugam Oya and Ja-ela. The Negombo Lagoon and its coastal environment have had a long association with the fishery industry. The salinity of Negombo Lagoon is strongly related to the monsoon rains and varies from almost zer...
