Abstract

Flood is considered as one of the most important and destructive natural disaster in the world. It leads to numerous {financial, environmental or human} losses not only in suburban areas, but also in urban areas. Man-made changes in the pattern of natural drainage systems in urban areas and main cities are considered as the significant factor of flood and disastrous consequences of it. The increase in the frequency of FLOODING in recent years suggests that most parts of the country are exposed to flood attacks. The main goal of this project is to study the status of the ABSHOORAN watershed FLOODING in South-West of KERMANSHAh city, and to evaluate the flood volume leading to the city and the Performance of surface-water disposal channels in this area. For this purpose, after digitizing data in Geographical Information System (GIS), different map layers, including rainfall, lithology, soil and land units, drainage density, slope and land cover was produced. Then flood risk assessment and zoning were performed with Analytic Hierarchy Process (AHP) method and the reasoning approach was applied for assessing the discharge FLOODING. The results showed that about 30 percent of the watershed area has a high potential for FLOODING. Also estimation of maximum discharge FLOODING and pervious experiments indicated that the disposal of surface-water channels in this part of the city of KERMANSHAh have not the ability to pass flood and in the event of further FLOODING, the city is going to suffer flood damages again. So for the purpose of reducing FLOODING in ABSHOORAN watershed, the relevant authorities should plan and implement projects to forecast the necessary requirements for improving the surface-water disposal system of channels of this area.
