Abstract:
During the recent years quantifying the impacts of land use change and land cover practices has been an area of interest for the hydrologists as this information is of great importance for developing better watershed management interventions. The degree and type of land cover influences the rate of runoff, infiltration and total sediment load transported from a watershed. In the present study the hydrology of Kaushalya Dam watershed located in Kaushalya River basin in Panchkula district of Haryana has been modeled using the Soil and Water Assessment Tool (SWAT).The dam has been constructed to create a reservoir to provide freshwater to the city of Panchkula in the state of Haryana. The study has been necessitated for the purpose of estimating the volume inflow to the Kaushalya dam located at the outlet of the watershed in order to develop an efficient decision frame work to facilitate, plan and assess the management of this important reservoir. The ArcGIS( version 10.2.2) software was used to delineate the study area and its sub-components, to combine the data layers and to edit the model database. The GIS based morphometric analysis has revealed the Kaushalaya basin to be of dendritic nature indicating lack of structural control. Bifurcation ratio, length ratio and stream order of the basin indicated that Kaushalay river basin is a fifth order basin with dendritic type of drainage pattern. Further drainage density and texture ratio, showed that the basin has a moderate texture and is nearly elongated. The results of the study indicated that during the recent past the land use patterns have changed resulting in increase in barren and build-up land and a decrease in forest cover, leading to increase in runoff. The model was calibrated and validated with available data from the year 1998 to 2017. The water balance components were correctly estimated and the inflow in the Kaushalya Dam was successfully computed.
