Flood hazard zoning using geographic information system (GIS) and HEC-RAS model (Case study: Rasht City)
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...

متن کاملFlood zoning estimation and river management by using HEC-RAS and GIS model
Reliable estimates of river stream fl ow and fl ood zoning maps are needed for water resourcesmanagement such as fl ood mitigation, water supply, dam construction and irrigation. Flood zoning needsaccurate data and is one of the non-structural fl ood management methods. This paper describes theapplication of HEC-RAS and GIS model to determine fl oodplains maps for the part of Sardabrud Rivertha...

متن کاملRCP8.5-Based Future Flood Hazard Analysis for the Lower Mekong River Basin
Climatic variations caused by the excessive emission of greenhouse gases are likely to change the patterns of precipitation, runoff processes, and water storage of river basins. Various studies have been conducted based on precipitation outputs of the global scale climatic models under different emission scenarios. However, there is a limitation in regionaland local-scale hydrological analysis ...
