Conclusions► The practical benefit of this research is <strong>the</strong> development ofa digital landscape <strong>analysis</strong> tool (PIT) to determinecontributing areas at varying <strong>pothole</strong> storage levels► Incorporating <strong>the</strong> dynamic nature of <strong>prairie</strong> <strong>pothole</strong>contributing area has <strong>the</strong> potential to improve land surfaceschemes as well as general circulation and <strong>region</strong>al climatemodels applied in <strong>the</strong> <strong>prairie</strong> <strong>pothole</strong> <strong>region</strong>.► Ongoing research is focussing on <strong>the</strong> application of curveparameters as a method <strong>for</strong> characterizing <strong>prairie</strong> <strong>pothole</strong>landscapes in <strong>region</strong>al scale hydrological models
