California Water Cycle

California Water Cycle

Water cycle modeling connects the physics between groundwater, surface water, and the atmosphere. Jason Davison models the complete California system using 3D models, and explores the feedbacks between the two systems. 

Check out his work below and at the European Geophysical Union (EGU) on Monday morning (April 13).

Water Cycle Modeling

I coupled HydroGeoSphere (HGS), a three-dimensional integrated surface and subsurface flow and energy transport model, to Weather Research and Forecasting (WRF), a nonhydrostatic Mesoscale three-dimensional numerical weather model. HGS replaced the land surface components of WRF and provides the evapotranspiration and saturation from the porous media to the atmosphere. WRF provides HGS with the potential evapotranspiration and precipitation. 

I’m currently working on modeling all of California, with the goal of finding the relationship between water resources and the climate. We are also looking at the current drought in California and study the future climate under the new precipitation patterns. 

Our work on California is still in the early stages and our results are showing the initial spin-up period before quasi-equilibrium. I’m presenting my research at the  Universität Tübingen this week and to EGU (Monday, 13th morning) next week.
