Runoff 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 کاملDerivation of unit hydrograph using a transfer function approach
[1] The unit hydrograph (UH) concept and model have been widely used in the hydrological field over the past decades. However, the estimation of such a model in practice has always been a challenge for researchers and practitioners because such a model is usually ill formed in mathematical terms. The large number of parameters (or the number of ordinates) in a unit hydrograph model are correlat...
متن کاملcalculated 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 کاملSynthetic Unit Hydrograph Methods: A Critical Review
The present study critically reviews the synthetic unit hydrograph (SUH) methods available in hydrologic literature. The study reveals that the traditional methods of SUH derivation, e.g., Snyder, SCS, traditional methods like Snyder and TS method that does not yield satisfactory results, and their application to the practical engineering problems is tedious and combursome. On the other hand, p...
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...
