Exploring climatic impacts on water resources in West Niger, Africa IRD
Vieux, R.E.; Looper, J.P.; Cappelaere, Bernard; Peugeot, Christophe; Maia, A..
Drought persisting in the Sahel for more than 25 years, impacting both surface and subsurface water resources, raises the question whether the hydrological impacts are proportional, dampened, or amplified in response to the climatic change manifested by the drought experienced since 1970. A physically-based distributed model, r.water.fea, applied to a 2.48 km2 endoreic drainage basin, typical of the Niamey area of West Niger, is used to evaluate the sensitivity of the hydrological system to such climatic extremes under four reduced-rainfall scenarios. Scenarios are built by elimination of various subsets of recorded storm events from the four monitored seasons 1992-1995. The hydrological response varies from no decrease to nearly a 30% decrease depending...
