River Flow Simulation by Integrating Numerical Methods and Satellite Images

Numerical models have the ability to simulate river flow by using mathematical relations under certain initial and boundary conditions. Investigating the capability of different models for simulating flow characteristics in a river reach such as flow depth, velocity and shear stress in river banks are one of the basic needs in river engineering. However, from the practical point of view, the minimum need for field information, the small computation, and the degree of trust of the application of mathematical models in the conditions of natural rivers is of great importance. The aim of this study is to integrate GIS and HEC-GeoRAS with HEC-RAS model in order to simulate the hydraulic parameters of the Karun River in Khuzestan province.
