Subsurface structure plays a key role in how watersheds respond to climate variability, influencing water storage, flood risk, and water quality beyond what surface features alone can explain.

The hidden physics of watersheds: Why some are more sensitive to climate variability than others
Water is everywhere, from the snowpack in the mountains to the tap in our kitchens. But while we often think about rainfall and snow as the main drivers of our water supply, it turns out that something we rarely see has just as much influence: the underground structure of the landscape itself.

Time-variance in catchment hydrologic function: why do some catchments show it and others don't? Our paper shows that subsurface structure mediates climate-induced year-to-year variability of catchment hydrologic function

Time Variance in Snowmelt Partitioning: A Mechanistic Modeling Approach to Explore the Role of Catchment Structure and Pre‐Snow Rainfall
Pre-snow rainfall variability alters snowmelt partitioning pattern (SPP) into storage versus runoff, with the magnitude of impact mediated by the extent of hydraulic conductivity's lateral heterog...

Deep Learning predicts streamflow beautifully. But does it "think" like a hydrologist? Our WRR paper shows the answer is no, with implications for hydrologic forecasts. Good news: we can diagnose this. Our new XAI framework opens the black box using hydrologic principles.

Do all catchments exhibit nonlinear and non-stationary behavior? A large-sample analysis of stormflow events reveals that the simple dynamics of Linear Time-Invariant systems are surprisingly common along wet/steep out-of-phase catchments. Read here:
