RHESSys was used in two Sierra Nevada study catchments to simulate how future warming could affect the relationship between winter snowpacks and summer low flows. The influences of groundwater storage, snowmelt, evapotranspiration rates, and precipitation phase (snow vs rain) on catchment response to warming are considered. The research was published in Hydrological Processes in the paper “Effects of changes in winter snowpacks on summer low flows: case studies in the Sierra Nevada, California, USA”
