E. Servat et A. Dezetter, RAINFALL-RUNOFF MODELING AND WATER-RESOURCES ASSESSMENT IN NORTHWESTERN IVORY-COAST - TENTATIVE EXTENSION TO UNGAUGED CATCHMENTS, Journal of hydrology, 148(1-4), 1993, pp. 231-248
Most development projects in northern Ivory Coast require good water r
esource management. Rainfall-runoff modelling was performed in 20 catc
hments (100-4500 kM2) to provide reliable tools for the assessment of
water supply in the sudanese savannah area. After the calibration of t
wo conceptual models (GR3 and CREC), the parameters were characterized
so that these models could be applied to ungauged catchments. Predete
rmination equations were established using variables related to the ca
tchment land use and the rainfall distribution over the year. The GR3
model produced good results although further work is needed to improve
the reliability of the equations before operational use.
