Rainfall is the main driver of the river discharge and as such of the flooding of the Inner Niger Delta. Information on rainfall is therefore essential in the flood predictions in OPIDIN. In this Section regularly updated information on recent rainfall in the Upper Niger Basin is given as well as the rainfall forecast.
OPIDIN is developed to serve as Early Warning System to the communities in the delta. It is inspired by their knowledge of the delta, and the way they adapt their way of living to that (OPIDIN avant la letter). In this Section the (technical) background of OPIDIN is briefly sketched.
To inform the communities in the delta and elsewhere in Mali and abroad about the flood forecast, this website is updated each week between 1 August and 15 October. The flood forecasted is updated continuously and news bulletins are given weekly, also on several radio stations.
