Effects of aquatic vegetation on sediment transport

In the margins of continents there are the coastal zones, regions of remarkable biological productivity. Coastal zones include, among others, wetlands, that are land areas inundated permanently o seasonally, characterized by the presence of aquatic vegetation adapted to the hydric soil. Therefore it...

Sumario:In the margins of continents there are the coastal zones, regions of remarkable biological productivity. Coastal zones include, among others, wetlands, that are land areas inundated permanently o seasonally, characterized by the presence of aquatic vegetation adapted to the hydric soil. Therefore it is necessary to consider the effect of aquatic canopies in wetlands investigations. These areas are governed by physical forces originated from tidal currents, waves, winds, night convection and floods. The aim of this thesis is to study the sediment transport in wetlands in which fluid is dominated by a) progressive waves, b) nearly isotropic turbulence and c) extreme flooding events
