ABSTRACT

Studies on Soil and Water Assessment Tool (SWAT) application in Sub-Saharan Africa were reviewed and evaluated mainly on basis of Nasch-Sutcliffe Model Efficiency (NSE). Most of the reviewed studies gave satisfactory results on performance while sensitive parameters were identified.The review studies highlighted lack of some input data which affected SWAT simulation in some catchments. Generally, the review observed that not much attention were given to crop parameters such as the leaf index. A better simulation will occur if crop parameters are taken into consideration as these will help in obtaining a better evapotranspiration, runoff and erosion simulation.


Keywords: Soil and Water Assessment Tool; hydrologic model; sub Saharan Africa
