1 - Evaluation the hydrodynamic and morphology changes in Sefidrood river estuary

In this research, the flow and sediment pattern were investigated using MIKE21 model in the Sefidrud River and how the influence of flow pattern, sediment transport and sea water level changes on evolution of the delta and coastline were studied by landsat. The factors such as flow and sediment load of the river, sea level, wind and wave pattern are the most important factors which affect these changes. This study can provide a properly field for a right management in order to the region’s sustainable development, adequate knowledge of the Sefid-Roud hydrodynamic and sediment situation in estuary area, as well as taking the necessary measures to prevent damages caused by the Caspian Sea’s long-term fluctuations in the Sefid-Roud’s deltaic region.
