Research Areas
From Raindrops to Streamflow
We investigate how rainfall is transformed into runoff, streamflow, and sediment response across multiple spatial and temporal scales. Our research integrates rainfall variability and dispersion, catchment runoff generation, flow routing, river hydraulics, hydraulic geometry, and sediment transport. Through theoretical, numerical, and observational approaches, we seek to understand the nonlinear, dispersive, and scale-dependent processes that connect individual raindrops to integrated river-basin responses.
