There is a need for a water quality model for use in the Lake Victoria basin countries in East-Africa. The region is characterised by data scarcity, a tropical climate and riverine, lacustrine tidal wetlands which form an important buffer to riverine pollution of the lake. These characteristics of the basin form a challenge for water quality models. The objective is to state the strengths and weaknesses of a potential water quality model under these challenging conditions. This objective is executed with the soil water assessment tool (SWAT) in a catchment of the Lake Victoria Basin as pilot area. The pilot area of the Mara river basin is hydrologically complex containing tropical and plantation forest, savanna, grasslands, bi-annual agriculture, shrublands and wetlands. It has varied soil types and bi-annual rain seasons The study consist of literature research and flow simulation of the transboundary Mara river basin. The model study aims to characterise the hydrology in the pilot area. The study includes a thorough analysis of rainfall, stage and flow data. Model preparation steps include the use of weighted-area rainfall estimation methods, climate model data and empirical derivation of soil input parameters. Discharge calibration methods include multi-site calibration, by making use of an alternative objective function statistic for the commonly used Nash-Sutcliffe Efficiency (NSE) called the Kling-Gupta Efficiency (KGE). The literature study targets previous flow and water quality studies done in tropical or wetland areas, thereby looking to see how these studies adapted to hydrological modelling with SWAT in tropical or wetland areas, and why theses adaptions were made. The literature research also includes a comparison of wetland processes in SWAT with the physical, biological and chemical processes as described in previous studies. The Mara river basin flow simulation gave a satisfactory model performance for two out of three calibration sites, thereby being able to give preliminary outputs on water-balance and other flow characteristics. During research, a number of model, knowledge and data gaps were found to be critical for better understanding the hydrological and water quality system workings in the Lake Victoria and Mara river basin. From the model and literature study it is concluded that several issues on data scarcity and hydrological model processes in the tropics can be overcome. These do not necessarily decrease model performance or uncertainty in the SWAT model. However, wetland processes are oversimplified in SWAT. Modification and coupled SWAT models yet have not been able to provide an alternative to the default model that adequately represents the main flow, sediment and nutrients processes and fluxes that are present in Mara’s wetlands.]]>
