1. Hydrological and sediment yield modelling in Lake Tana Basin, Blue Nile Ethiopia
Abstract : Land and water resources degradation are the major problems on the Ethiopian highlands. Poor land use practices and improper management systems have played a significant role in causing high soil erosion rates, sediment transport and loss of agricultural nutrients. So far limited meas-ures have been taken to combat the problems. READ MORE

3. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry
Abstract : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. READ MORE
