Synthetic 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 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 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...
متن کاملGroundwater Unit Hydrograph Evaluation of Niriz Plain
Groundwater is one of the most important water resources in Fars province. Based on this study, 95 percent of the total annual water consumption in Fars is used for agriculture, whereas the percentages for domestic and industrial uses are 4 and 1 percent, respectively. Population growth, urban and industrial growth, and agricultural development in Fars have created a condition of water stress. ...
متن کاملOn the Clark Unit Hydrograph Model of HEC-HMS
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.
