Objective:
To reconstruct the past 30 years of hydrologic change in North America and to project coupled climate-hydrologic changes in the next 50 years under IPCC scenarios.
Progress Summary:
During the first year of the project, we have (a) set up the model domain and processed land surface parameters, (b) downloaded and processed the atmospheric forcing data from North America Regional Reanalysis or NARR, (c) compiled observations of stream flow and groundwater level over the past decades for model validation, (d) completed model initialization of water table depth and soil moisture, (e) began simulations of land hydrology over the past 30 years, (f) completed initial validation and model improvements, (g) obtained super-computing and data storage resources at NCAR and San Diego Super Computer Center, and (h) examined observations and justified the need to include human withdrawal for irrigation in the coupled climate-hydrology model simulation.
Future Activities:
During the second year of the project, we plan to (a) complete the 30-year retro-simulation of North America land hydrology with human withdrawals using LEAF-Hydro, which is task 1 of the project; (b) complete the 10-year retro-simulation of coupled climate-hydrology using WRF-Hydro, which is task 2 of the project; and (c) include human withdrawal in the modeling framework. During the third and final year of the project, we will perform multiple 50-year coupled simulations using WRF-Hydro with boundary conditions provided by the various IPCC climate projections, to assess likely future changes in land hydrologic stores (groundwater, soil moisture, river flow and wetland distribution) and fluxes (rainfall, evapotranspiration, groundwater recharge, and stream flow) under climate change and expansion of human footprints on land hydrology.
