Abstract
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.
