sedimentation is one of the most important problems in harbors that results in considerable economic costs. harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. in the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...

Sediments represent a critical compartment of marine coastal ecosystems due to the toxic and long-lasting effects contaminants buried therein. Here, we investigated properties surficial sediments in front Southern Marche Region coast (Central Adriatic Sea, Italy). The grain size was determined by X-ray sedigraphy. TN OC contents were elemental analysis. concentrations Al, Fe, Mg, K, S, Ca, Ti, ...

During a cycle of sea-level variation, coastal environments develop in different position the continental shelf following seaward and landward shift coastline. They vary widely character, reflecting wide range process-regimes that are brought about during stages variations. Within this scenario, morphology shelves, mainly resulting from combined effect tectonic activity eustatism, plays an impo...

Changes in shoreline configurations accelerated due to global warming are world wide concern. Such changes not only affect the flora and fauna of those regions but also the livelihood of the coastal population. In the context, the 7517km long coastline of Indian coast behaves differently in different regions. Therefore, in order to assess the shoreline changes taking place in particular coastal...

The U.S. Survey acquired analyzed physical ...

In the present research, the aqueous suspensions of nano-sized YSZ particles were prepared using a common and available dispersant (Dolapix CE64) at different pH values and their stability were evaluated through the sedimentation height, viscosity measurement, and microstructural observation. Different amounts of dispersant were tested and the optimum percentage was examined by measuring the vi...
