Analisa Keseimbangan Air (Water Balance) pada Sub Daerah Aliran Sungai Bedagai

Abstract

Water balance is a situation in which the inflow and outflow are the same. So, by looking at the water balance, we can know the water balance. The purpose of this study is to obtain the value of the components of the water balance in the Bedagai sub-watershed. This study uses a descriptive method with observations in the field. In this research primary data and secondary data will be analyzed. The tool used in this research is the WL16U Global Water Level Logger type to collect water level data, in order to calculate flow velocity. The results of this study show that the water that comes out as plant evapotranspiration is 1357 mm/year, the water that comes out as surface runoff is 531 mm/year, and the water that comes out for domestic water needs is 972 mm/year. In addition, there is a deficit of 27 mm/year, and a surplus of 281 mm per year
