calculated geomorphologic instantaneous unit hydrograph (giuh) and width-function based instantaneous unit hydrograph (wfiuh) in the ungauged watershed
the role of unit hydrograph is very important in prediction of floods in the rivers, design protection and control structures in the catchment area. therefore in the basin without hydrometric stations, by using mathematical and empirical relationship and based on climatic data, the water level in the basin is estimated. two methods of geomorphologic instantaneous unit hydrograph and width funct...
متن کاملRunoff simulation using geomorphological instantaneous unit hydrograph (GIUH). (case study: Bar basin-Khorasan Razavi)
Considering the most of country have no gage station, in recent year one method can be proposed with the involvement of other information, which will affect hydrology condition. It can estimate flood water level. In this study, considering relationship between geomorphology and hydrology, using little information, flood hydrograph were simulated. This method is named geomorphological instantane...
متن کاملStudy the Effect of used Parameters on Geomorphologic Instantaneous unit Hydrograph
Estimating the runoff in the basins lacking statistics is always considered by researchers And managers in planning, development and implementation of many projects of water Resource. One of the methods for estimating the runoff is to use geomorphology instantaneous unit hydrograph which estimates the hydrograph of flood based on quantitative geomorphology factors. In this study, first the quan...
متن کاملGeomorphologic Instantaneous Unit Hydrograph Stream Flow Simulation for the Yalobusha River Basin, MS
In erosion and sedimentation problems, estimating the range of significant stream flows to include when computing sediment transport can prove challenging in ungauged or under-gauged basins. This paper describes an event-based model incorporating a geomorphologic instantaneous unit hydrograph and stochastic descriptions of peak flows and frequency of storm events from nearby reference watershed...
متن کاملDerivation of Nash Model Parameters from Geomorphological Instantaneous Unit Hydrograph for a Himalayan River Using Aster Dem
The most widely and popularly used method for prediction of flood hydrograph resulting from a known storm in a basin area use historical rainfallrunoff data and unit hydrographs derived from them. These procedures are highly unreliable due to the climatic and physical changes in the watershed and their implementation to ungauged catchments. The use of physically based rainfall-runoff estimation...
