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.
