      abstract     = {This study investigates the robustness of the
                      physically-based hydrological model WaSiM (water balance and
                      flow simulation model) for simulating hydrological processes
                      in two data sparse small-scale inland valley catchments
                      (Bankandi-Loffing and Mebar) in Burkina Faso. An intensive
                      instrumentation with two weather stations, three rain
                      recorders, 43 piezometers, and one soil moisture station was
                      part of the general effort to reduce the scarcity of
                      hydrological data in West Africa. The data allowed us to
                      successfully parameterize, calibrate (2014–2015), and
                      validate (2016) WaSiM for the Bankandi-Loffing catchment.
                      Good model performance concerning discharge in the
                      calibration period (R2 = 0.91, NSE = 0.88, and KGE = 0.82)
                      and validation period (R2 = 0.82, NSE = 0.77, and KGE =
                      0.57) was obtained. The soil moisture (R2 = 0.7, NSE = 0.7,
                      and KGE = 0.8) and the groundwater table (R2 = 0.3, NSE =
                      0.2, and KGE = 0.5) were well simulated, although not
                      explicitly calibrated. The spatial transposability of the
                      model parameters from the Bankandi-Loffing model was
                      investigated by applying the best parameter-set to the Mebar
                      catchment without any recalibration. This resulted in good
                      model performance in 2014–2015 (R2 = 0.93, NSE = 0.92, and
                      KGE = 0.84) and in 2016 (R2 = 0.65, NSE = 0.64, and KGE =
                      0.59). This suggests that the parameter-set achieved in this
                      study can be useful for modeling ungauged inland valley
                      catchments in the region. The water balance shows that
                      evaporation is more important than transpiration $(76\%$ and
                      $24\%,$ respectively, of evapotranspiration losses) and the
                      surface flow is very sensitive to the observed high
                      interannual variability of rainfall. Interflow dominates the
                      uplands, but base flow is the major component of stream flow
                      in inland valleys. This study provides useful information
                      for the better management of soil and scarce water resources
                      for smallholder farming in the area},
