Hydrological modeling of the Kihansi river catchment in South Central Tanzania using SWAT model

  This study presents distributed and lumped hydrological modeling approaches for the Kihansi river catchment in south central Tanzania using the Soil and Water Assessment Tool (SWAT). The catchment is source of water for the Lower Kihansi Hydropower Plant (LKHP) that supplies 25% power to the national grid and the bio-diverse gorge eco-system in lower Kihansi Basin. In the distributed modeling sub-watersheds...

Introducing sand filter capping for turbidity removal for potable water treatment plants of Mosul/Iraq

  Sand filter capping had been tried as an alternative for the currently practiced rapid sand filters. A 1000 m3/day capacity pilot plant constructed similarly to full scale water treatment plants was used for this purpose. Four levels of sand material with respect to grain size and thickness were used. Capping filter was represented by one level of anthracite coal with one thickness. In order to optimize...
