Accurate representation of hillslope water dynamics by a land surface model (LSM) is important when seeking to describe water and energy conditions precisely at fine space scales. That being said, the complex land surface conditions (e.g., the land cover type) that directly affect these dynamics and therefore influence the land water and energy status are treated in a simple manner, which is yet to be thoroughly addressed. In this study, we included hillslope heterogeneity in a LSM and assessed the impact thereof on terrestrial water and energy budgets across the African continent. The results show that, hillslope water dynamics aside, more realistic representations of hillslope vegetation distribution that roughly matched differences in soil water contents (e.g., denser vegetation along riversides in arid regions) revealed several distinct forms of soil water movement and evapotranspiration over the African continent. Validated by observed discharge and soil moisture, the results of modeling that considered the complex land surface conditions were more accurate. We emphasize the need to resolve hillslope water dynamics and land cover heterogeneity explicitly if a LSM is to be appropriate.
