Watershed Hydrology Lab
at UC Santa Cruz
at UC Santa Cruz
The Watershed Hydrology Research Lab studies how rainfall becomes runoff, the pathways water takes through landscapes, and the biogeochemical implications of these pathways.
We combine field and quantitative analyses to explore rainfall-runoff relationships and surface water- groundwater interactions across a broad range of spatial and temporal scales.
