Ruaha River Flow Monitor

A river flow monitor tool to alert for extreme low river flow and zero flow using remote sensing. The Alerts allow for timely action to prevent or reduce the period of Zero flow in most of the Ruaha National Park. Zero-flow can have negative impact on domestic water supply, nature, in particular wildlife and economic activies and should be mitigated through negotiations between the water users. For Ruaha River (Tanzania) the Monitor will be active from April with the prediction of the first Zero Flow Event until the occurrence of the Rains.

Early Irrigation Kapunga – Zero Flow Park HQ

Early Irrigation Kapunga – Zero Flow Park HQ Expansion pre-irrigation limited by low availability of water in Ruaha The very limited flow remaining in the Ruaha hampers the expansion of pre-irrigation in Kapunga and Mbarali. The pre-irrigation on November 27, 2023 in Kapunga Scheme, is indicated by green circles. The clouds in the NBR imageContinue reading “Early Irrigation Kapunga – Zero Flow Park HQ”

How To Detect Return Flow from New-NAFCO canal to Mbarali River

How To Detect Return Flow from New-NAFCO canal to Mbarali River The Mbarali New NAFCO Main Canal has a small hydro power plant using 1 cumecs. Immediately downstream of the plant a return drain is constructed to secure return of the 1 cumecs to the Mbarali River after passing through the turbine. The practice ofContinue reading “How To Detect Return Flow from New-NAFCO canal to Mbarali River”
