Development of Synthetic UH by Using Geomorphologic Instantaneous Unit Hydrograph (GIUH) Based Nash Model
The present study is aimed at developing a methodology suitable for the development of unit hydrograph for un-gauged catchments. As we know in developing countries like India, there is a paucity of the gauged catchment. Research has been done to seek out this problem. In this research, we have found different ways to find the geophysical characteristics of un-gauged catchment. In previous times, there were certain methods to find the geomorphologic characteristics, but these methods were very difficult to apply and time consuming, so our first need was to overcome these problems. There were certain softwares like ILWIS, GRASS, and ERDAS which were introduced and used to find the characteristics in much less time than before and with much more ease. In this research, data is evaluated from DEM through Arc-GIS. This research uses GIUH-based NASH model. Through this model, better instantaneous unit hydrograph was found as compared to any other techniques that were applied in previous time. The curve found through this model is exactly same as the ideal curve.
