Abstract
This study was carried out to estimate direct
recharge in the Sokoto-Rima river basin, Nigeria,
using a soil moisture deficit model. Thereafter,
the sensitivity of the model to input and model
parameters was investigated. The mean annual recharge
for the study period was found to be 255.0mm. The
incidence of recharge was validated by comparison
of the recharge estimates with well hydrographs
obtained in the region. Further studies would be
required before the amount of recharge can be fully
validated.
The results of the sensitivity analysis show
that variations in rainfall and potential
evapotranspiration values significantly affect the
direct recharge values. From the experience gained
in this study, one would call for a more efficient
system for data collection, storage and retrieval
