Book excerpt: Hydrology in semi-arid areas is highly impacted by changes in land cover and climate, and research and management are dependent on tools to assess change. Research will be presented that describes methods for mapping and modeling land cover and climate changes and their effects on hydrological systems. Land cover mapping using fast Fourier transforms showed high accuracy compared to traditional techniques. Exploitation of land for natural gas infrastructure is an important form of land use change in the Big Piney-La Barge Oil and Gas Field development area. We used a calibrated SWAT model to simulate hydrology before and after development in this research. Methods for modeling spatially explicit future land management scenarios were built into a GIS system and used in hydrologic models to forecast potential changes to the hydrologic cycle. The KINEROS2 hydrological model was used to simulate hydrology in this study to show the impacts of different management practices. The WRF climate model was used in conjunction with the calibrated SWAT model with the aid of automated calibration to forecast future climate, with the results ingested by a hydrologic model to assess potential impacts on water yield.
