Sebastian Gnann (WISE CDT, University of Bristol) talks about his research collaboration with Hilary McMillan (San Diego State University)

Climate exerts a strong control on the hydrologic response of a catchment. Yet we see marked differences between catchments forced by a very similar climate, particularly if we look at the slow response (e.g. baseflow). This is often attributed to differences in soils or geology. The influence of non-climatic catchment attributes is, however, rarely captured in large sample studies, which often only find climate characteristics to be a good predictor of the hydrologic response. In this presentation, I will show that a closer look at the geology of different regions reveals the strong control the subsurface exerts on streamflow dynamics.
