The purpose of this paper is to estimate the water balance in a semi-arid environment with limited in situ data using a remote sensing approach. We focus on the Lake Manyara catchment, located within the East African Rift of northern Tanzania. We use a distributed conceptual hydrological model driven by remote sensing data to study the spatial and temporal variability of water balance parameter...

Simulation of Water Balance Components (WBCs) is import for sustainable water resources development and management. The Soil Assessment Tool (SWAT) a semi-distributed hydrological model to estimate the WBCs by forcing response unit (HRU) meteorological variables. developed simulates five viz. surface runoff, lateral flow, percolation, actual evapotranspiration soil at sub catchment level. To de...
