Description

Climate change is expected to create many challenges (including water availability) worldwide and projecting the impacts of climate change at regional scale allows communities to be proactive in planning for the future. It will help to prepare a future plan for the water resources development and management for the basin. Therefore, the quantifications of the different components of the water balance at basin scale and the impact of climate change on them is required. The study was planned for estimating the runoff, evapotranspiration and groundwater recharge by SWAT model and assessing the impacts of climate change on potential surface and ground water resources of basins. The study was undertaken in two river basins i.e. Sani river basin and Vartu river basin of Devbhumi Dwarka district which is located in Southern region of Gulf of Kutch of Gujarat state Sani river is of 60 km long and entire basin area nearly 854 km2. It originates from village Sonardi and meets to Arabian Sea near Gandhavi village. Vartu river is of 63 km long with area of basin nearly 1145 km2.
