On 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.
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 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 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 کاملPractical aspects of calibrating and selecting unit hydrograph-based models for continuous river flow simulation
A continuous simulation rainfall-streamflow modelling approach that identifies unit hydrographs for total streamflow has been applied to an 11-year record from a national hydrometric monitoring network catchment in the UK. The model is of the parametrically parsimonious conceptual model (PPCM) type that can make efficient use of rainfall, streamflow and air temperature data readily available fr...
