Research

Great Lakes Basin

I am currently developing a hyper-resolution model for the entire Great Lakes Basin. This model, employs the HydroGeoSphere simulator, and includes all five of the Great Lakes (Superior, Michigan, Huron, Erie, and Ontario), primary tributaries/rivers, groundwater flow, and water use. The primary purpose of this work is to understand and estimate the future risk (over the 21st century) to water resources within the GLB from climate change and extreme weather.

 

Hydrogeosphere - Weather Research and Forecasting (HGS-WRF)

This video shows a 200 day simulation of the California Basin model. I implemented the coupled HydroGeoSphere-Weather Research and Forecasting (HGS-WRF) model for January 2011 to August 2011 (200 days). The simulation shows the Log Depth, Precipitation, Evapotranspiration and Change in Saturation (from initial condition).

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.  Learn more about the HGS-WRF and the California Water Cycle model here...

Canadian Continental Basin Model (CCBM)

Canadian Water Resources

Canadian Water Resources

The CCBM covers 10.5 million square km, spanning from the Pacific to the Atlantic Ocean, west to east, and from the northern parts of the Contiguous United States to the Arctic Ocean and Alaska, south to north. The 3D simulation domain was discretized using an unstructured triangular mesh with lateral inter-nodal spacing ranging from 400 m to 25 km. The mesh was refined along hydrologically important features, such as streams, watershed and lakes boundaries, and complex topography defined in the 1 km resolution HYDRO1K digital elevation model (USGS). Overall, the integrated surface-subsurface CCBM finite element mesh consists of 1.8 million nodes and 3.2 million elements.

 

HYDROGEOSPHERE - Atmospheric Boundary Layer (HGS-ABL)

HGS-ABL Model domain

Advanced earth system modeling requires a comprehensive understanding of the major physical processes in the environment, including atmospheric dynamics, precipitation, evapotranspiration, surface energy balance, surface water, and groundwater flow. We combined the above phenomena into one numerical model, referred to as HydroGeoSphere-Atmospheric Boundary Layered model (HGS-ABL), that incorporates the surface, subsurface and simple atmospheric dynamics. HGS, a 3-D control-volume finite element surface/subsurface model, handles the bottom portion of the domain whereas the ABL model, a single 0-D element atmospheric code, addresses the top portion.
