Rain is the main manifestation of the monsoon. Rainwater is an essential link in the epidemiological chain of some water borne diseases such as malaria, Rift valley Fever (RVF) etc. The last one is a pathology transmitted by mosquitoes not only to men, but also to animals. The proliferation of these mosquitoes is strongly dependent on the hydrological dynamic of the ponds: mosquitoes ly in the ponds, and ponds are also larva shelters.
Understanding the hydrological behaviour of the ponds allows us to know the dynamic of these related larva shelters and by the way to develop an earlier warning system to protect men and animals against malaria and RVF.
The rainfall-runoff model becomes a standard approach of understanding the continental water cycle for river flow forecasting and the ecosystem protection.
Our aim in this work is to first run a rainfall-runoff model to simulate area’s water of three ponds (Niakha, Kangaledji, Ngao) located in the zone of Barkedji in Northern Senegal, and then to link it to the mosquitoes proliferation in an early warning system against malaria and RFV. Morphometric characteristics of each pond have been estimated and compared between themselves, and characterics curves established. Hydroclimatic variables have been analysed and criticized for independence and homogeneity through relevant statistical tests. Two empirical hydrological models have been run: one based on hydrological balance, and another based on the recession curve. The results we have obtained are promising. They have given us a first idea of the hydrological behaviour of the three ponds. We will then relate this behaviour to the mosquitoes proliferation and RFV.
