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...

The Muskingum-Cunge flood routing procedure has been incorporated into the Natural Resources Conservation Service Technical Release 20 (TR-20) hydrologic model. The TR-20 model is an event watershed hydrologic model used to analyze impacts of watershed changes (land use, reservoir construction, channel modification, etc) on volume of runoff and peak discharge. Rainfall runoff modeling is very i...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract This paper presents a case study to estimate peak discharges of extreme flood events of Neckar River in southwestern Germany during the 19th century. It was carried out within the BMBF research project RIMAX (Risk Management of Extreme Flo...

Flood is considered as a major threat among natural disasters in the world. This case becomes more important and has a higher risk in urban areas due to the existence of important uses. Therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. Considering the development in Iran has been carried out in high risk...

The last few years have witnessed an enormous study in the area of integrated hydrological modeling with GIS application. In this research, attempt was made to critically look at the application of HEC-GeoHMS which is an extension of ArcView in HEC-HMS; an HEC package which is a new generation of software being developed for rainfall-runoff simulation. The main role of HEC-GeoHMS is to formulat...

due to increasing rate of flood risk throughout the world, including iran, it is necessary to identify and prioritize flood-contributing areas for flood control activities. in this study, a new approach on unit flood response method called “flood reduction method” was introduced which is applicable to prioritization of sub-basins for flood control activities. it was used to prioritize upstream ...
