Eric Small's Surface Water Research group focuses on the physical processes that regulate the water and energy budgets of the Earth's land surface. Vegetation, soil, and the atmosphere strongly influence surface water fluxes and storage and therefore are primary targets for the group's research. The processes studied act across a wide range of spatial and temporal scales, from the influence of plants on surface water redistribution during rainstorms to the effects of land-atmosphere interactions on decadal rainfall variability. The group's research combines modeling and data analysis, with the latter including measurements from the field, lab, and remote sensing. Graduate and undergraduate students participate in all aspects of this research.
