Fire and Precipitation Interactions

This is an extension of Jordan Lanini's Masters thesis. In this work we modified vegetation and soil properties in the Distributed Hydrology Soil Vegetation Model (DHSVM) to reflect the changes in these values in response to fire. The impacts of these modifications (to LAI, root cohesion, infiltration capacity) on streamflow and sediment was then evaluated under varying fire severities and weather sequences.

Drought Characterization

With Kostas Andreadis. Continuation of work done by HyoSeok Park to extend United States drought analysis to 1915 using Old Co-op meteorological forcing data. We created severity-area-duration (SAD) curves from this data, similar to depth-area-duration curves used in precipitation analysis, based on soil moisture and runoff percentile values.
