Predicting discharge and sediment for the Abay (Blue Nile) with a simple model.

The article focuses on a study in Blue Nile River which examines the development of simple hydrology and erosion models through the use of saturation excess runoff principles and interflow processes. It states that a water balance approach is used by dividing the landscape into variable saturated areas, exposed rock and hillslopes. It notes that available precipitation and potential evaporation data and a minimum of calibration parameters are used to couple the model with erosion model.
