The purpose of this study was to analyze the effect spillway width on flow elevation at weir crest based flood discharge design for Probable Maximum Flood (PMF) return period using routing hydrologically Cacaban Dam (Indonesia). rainfall Precipitation (PMP) uses Hershfield Equation. analysis QPMF used Nakayasu Synthetic Unit Hydrograph (HSS). hydrologic method. is located in Jati Village, Kedun...

In this paper, the modeling is based on division of the catchment into a grid mesh. Each cell has a unique response function independent of the functioning of other cells Summation of the flow responses from the cells, result the flow hydrograph from this area basin.A method is presented to simulation the flow hydrograph within a river basin using the hydrological model WetSpa. WetSpa is a GIS-b...

abstract flood causes great and uncompressible damage to people’s life and properties as well as environment each year in iran. this research was carried out at the west section of jazmurian basin that placed in the southeast of iran. in this research physical characteristics such as area (a), perimeter (pr), average elevation of basin (av.e), average slope (av.s), gravelious coefficient (g), l...

This paper describes an approach for the identification of flood-susceptible areas contributing to sustainability these in Giofiros river basin covering area 184 km2, located Southern Greece. is prone flooding with devastating consequences on people, environment, and economy. In this context, a geographic information system (GIS)–based multi-criteria decision analysis (MCDA) method potential fl...

Abstract An approach is presented for directly deriving a variable parameter Muskingum method from the St. Venant equations for routing floods in channels having any shape of prismatic cross-section and flow following either Manning's or Chezy's friction law. The approach also allows the simultaneous computation of the stage hydrograph corresponding to a given inflow or the routed hydrograph. T...

In recent years, the interest in the prediction and prevention of natural hazards related to hydrometeorological events has grown due to the increased frequency of extreme rainstorms. Several research projects have been developed to test hydrometeorological models for real-time flood forecasting. However, flood forecasting systems are still not widespread in operational context. Real-world exam...
