Sediment transport modelling: Determination of the main areas contributing to the suspended sediment load in the Mara River, Kenya

The Mara River originates in Kenya in the Mau Escarpment and flows through the Serengeti ecosystem into Lake Victoria in Tanzania; in total it is about 395 km long. In this river, human interventions have led to increased of agricultural areas. As a result, increased fast runoff and top soil erosion is expected. Consequently, more sediments is...

Behaviour of nourishments in quasi 3-dimensional graded sediment models

Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...
