Rivers are important water resources for human life, but sometimes cause irreparable damages. The flood plains are fertile terrains which are endangered by flood. Flood hazard mapping is one of the basic methods in flood fighting. In order to decline flood damages, the simulation of the hydraulic behavior of the rivers during flood occurrence is very important. In this study, areas that are flo...

This study is concerned with unsteady flow in open channels boundary conditions that may exist river or channel system. A software Hydrologic Engineering Center-River Analysis System (HEC-RAS) was used for a case study. The contains hydrodynamic model simulating the based on one-dimensional form of Saint-Venant equations, by formulating discrete using implicit finite difference scheme, then sol...

Objectives- A flood is a strangely high stage in river generally, the level at which overflows its banks inundates adjacent area. Flood occurs due to intense rainfall, dense population, industrialization, illegal settlement along riverbanks, bank erosion, tide, and urbanization, it causes harmful damage human beings properties. It can be taken care of by adopting risk measures. One measures dev...
