Excess sediment and nutrient losses from intensifying agriculture degrade water quality and boost plant growth. The relationship between circulation patterns, spatial water quality degradation, and water hyacinth infestation is not adequately studied. Th...

Climate change and its impact on surface runoff in the upper Blue Nile basin and sub-basins have been widely studied in future climate projections. However, the impact on extreme flow events of rivers is barely investigated discretely. In this paper, the...

A significant constraint in water resource development in developing countries is the lack of accurate river discharge data. Stage?discharge measurements are infrequent, and rating curves are not updated after major storms. Therefore, the objective is to...

Despite the fact that rice was only recently brought to Ethiopia, the Ethiopian government has dubbed it the ?millennium crop? because of its importance as a food security crop, as well as a source of revenue and job possibilities. Rice production is bei...

Sediment concentration of rivers in developing countries has been increasing greatly over the last 50 years due to the conversion of forest to continuously cultivated land with the increasing population. Few studies have addressed its effect on sedimenta...
