  abstract = {{W}ithin the framework of the {A}frican {M}onsoon {M}ultidisciplinary {A}nalysis ({AMMA}) {L}and {S}urface {M}odel {I}ntercomparison {P}roject phase 2 ({ALMIP}-2), this study evaluates the water balance simulated by the {I}nteractions between {S}oil, {B}iosphere, and {A}tmosphere ({ISBA}) over the upper {O}ueme {R}iver basin, in {B}enin, using a mesoscale river routing scheme ({RRS}). {T}he {RRS} is based on the nonlinear {M}uskingum-{C}unge method coupled with two linear reservoirs that simulate the time delay of both surface runoff and base flow that are produced by land surface models. {O}n the basis of the evidence of a deep water-table recharge in that region, a reservoir representing the deep-water infiltration ({DWI}) is introduced. {T}he hydrological processes of the basin are simulated for the 2005-08 {AMMA} field campaign period during which rainfall and streamflow data were intensively collected over the study area. {O}ptimal {RRS} parameter sets were determined for three optimization experiments that were performed using daily streamflow at five gauges within the basin. {R}esults demonstrate that the {RRS} simulates streamflow at all gauges with relative errors varying from -20% to 3% and {N}ash-{S}utcliffe coefficients varying from 0.62 to 0.90. {DWI} varies from 24% to 67% of the base flow as a function of the subbasin. {T}he relatively simple reservoir {DWI} approach is quite robust, and further improvements would likely necessitate more complex solutions (e.g., considering seasonality and soil type in {ISBA}); thus, such modifications are recommended for future studies. {A}lthough the evaluation shows that the simulated streamflows are generally satisfactory, further field investigations are necessary to confirm some of the model assumptions.},
