ABSTRACT: Groundwater is an important source of water supply for rural communities throughout Canadian prairies. Sustainable management of this resource requires estimates of recharge rates. The Groundwater Recharge in Prairies (GRIP) project attempts to fill this gap by producing a map of depression-focussed recharge for the Edmonton-Calgary Corridor (ECC) by the means of numerical modelling. Such recharge occurs during seasonal ponding of small depressions widespread in the area. A key step involved choice of parameters to be used in recharge modelling. In order to estimate these parameters, a terrain analysis script was developed and applied to a digital elevation model covering part of the study area. Modelling result highlighted a spatial variability of depression-focussed recharge rates and elucidated the role of limited depressional storage capacity in setting an upper limit for recharge.
