Abstract

The morphological studies and researches are very important for organizing the river and determining the river bed and zone. There are several hydraulic factors that make the scouring phenomenon intense at the location of hydraulic structures constructed on the beach of the river. The seawall erosion of river via water is regarded as the common and known phenomena of rivers of Khuzestan Province. So, execution of conservative practices and stabilization of side walls of the river is so essential. In the present research, the main aim is to determine the best method for stabilization of coastal on the basis of the study area by simulation and comparison of various conservation methods of coastal. For this purpose, a range of Zohreh River with the length of 60 Km was selected as the model area along with Coastal Protection structures. The organizing methods of the research encompass Groin, riprap layer, construction of the concrete wall, vegetation, embankment and submerged plates. First, the river was modeled in Arc View software using topographic maps and the obtained results were imported into HEC-RAS software for applying hydraulic conditions. Then, various parameters of flow under conditions of organizing methods were compared with current state of the river. Finally, the Groin-embankment option was selected as the best method in terms of hydraulic among alternatives, due to a %13. 5 reduction in shear stress relative to the existing conditions, implying erosion decrease of river coastal.
