  abstract = {{H}ill reservoirs are rain water-harvesting structures that have been increasingly adopted in arid and semi-arid regions, such as {N}orth {A}frica, to capture and conserve runoff water and for use as alternative water resources in agricultural development. {C}urrently, process-based information on reservoir hydrology is needed to improve reservoir management practices. {T}he study aims to develop an approach to estimate the reservoir-subsurface exchange flux and its associated error at the annual, monthly, and intra-monthly time scales to better understand the hydrological functioning and dynamics of hill reservoirs. {T}his approach is based on a hydrological water balance of the hill reservoir by considering all water input and output fluxes and their associated errors. {T}he results demonstrate the ability and relevance of the approach in estimating the net reservoir-subsurface exchange flux and its error estimations at various time scales. {I}ts application on the {K}amech catchment ({N}orthern {T}unisia) for the 2009-2012 period demonstrates that the net reservoir-subsurface exchange flux is positive, i.e. the infiltration from the hill reservoir to the aquifer dominates over the discharge from the aquifer to the reservoir. {M}oreover, reservoir-subsurface exchange constitutes the main output component in the water balance.},
