  abstract = {{R}unoff simulation in highly anthropized catchments is complex, but essential for water management, especially in poorly gauged and data-scarce hydrosystems of the {W}est {A}frican {S}ahel. {T}his study aims to evaluate the effect of different calibration schemes on runoff simulation. {T}he physically-based and semi-distributed hydrological {SWAT} ({S}oil and {W}ater {A}ssessment {T}ool) model is used to simulate daily runoff in the {N}akanb{\'e} catchment at {W}ayen station in {B}urkina {F}aso (in the {W}est {A}frican {S}ahel) over the period 2006-2012. {F}our (4) hydrometric stations ({D}ombr{\'e}, {R}ambo, {R}amsa and {W}ayen) gauging 4 nested catchments (ranging from 1060 to 21 178 km2 in size) are considered. {T}he added value of the consideration of nested catchments is assessed through the following 3 calibration schemes: one-site ({OS}) at the entire catchment outlet ({W}ayen); multi-sites with nested sub-catchments ({MS}1); and multi-sites without considering nested sub-catchments ({MS}2). {T}he results indicate that {OS} and {MS}2 schemes perform well ({KGE} > 0.7, |{PBIAS}|<3 %), with {MS}2 scheme being superior ({KGE}, {PBIAS}). {H}owever, the {MS}1 scheme ({KGE} = 0.68; {PBIAS} = - 22.9 %) performed worse in comparison to the traditional {OS} scheme. {T}he comparison of the three modelling schemes provides evidence that accounting for nested sub-catchments does not necessarily improve the quality of rainfall-runoff simulations. {Y}et, multi-site calibration should be favoured when catchments are not nested.},
