Estimating the Water Balance Component in Rangmati River Basin using Swat Model
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
It is necessary to understand the quantity and quality in space and time to utilize water resources in a sustainable manner. The soil and water assessment tool (SWAT) is used for estimating water balance component. The total 518 km2 area of river basin was subdivided into 7 sub watershed and 230 hydrologic response units (HRUs). The average of mean seasonal and annual water balance component showed that seasonal rainfall, seasonal runoff, seasonal groundwater recharge and seasonal ground water recharge was found increasing at 75.65 mm/decade, 47.32 mm/decade, 10.91 mm/decade and 12.10 mm/decade respectively while seasonal potential evapotranspiration and annual potential evapotranspiration was found as decreasing at 4.76 mm/decade and 2.71 mm/decade respectively.
