  abstract = {{I}s there a single combination of hydrologic model and data that yields the best simulations of runoff from a set of catchments in {W}est {A}frica in the coming decades? {T}o answer this question, a semi-distributed modelling platform was developed. {I}t comprises two models ({GR}2{M} and {W}ater {B}alance {M}odel) and various datasets as inputs to these models (three potential evapotranspiration [{PET}] grids and four soil water holding capacity [{WHC}] grids). {T}he platform makes it possible to regionalise runoff flows, which are discretised in grids of mesh size 0.5 degrees x 0.5 degrees. {O}n the basis of these datasets and models, we compare the performance of the various possible data-model combinations. {T}he study area contains 49 catchments located in {C}ote d'lvoire, {G}uinea, {M}ali, {B}urkina {F}aso and {N}iger. {T}he analysis shows that the selected models are hardly sensitive at all to the different {PET} grids but more sensitive to the soil grids. {T}he {GR}2{M} model clearly gives the best results for the set of catchments, but does not perform well over the entire study area, whatever the grid dataset used: {I}t is thus seen to be difficult to define a single data-model combination that is optimal for simulating runoff in {W}est {A}frica. {A}s to the existence of a "general" model that could be used anywhere, we find that, for the selected study area, neither of the two models selected fully meets the objective.},
