Aided by satellite data, modeling and understanding of the interactions between physical and human systems, more reliable regional LULCC and climate change projections are now available. However, resulting quantitative projection of changes on the hydrologic components at the seasonal time scale are sparse.

The Common Land Model (CLM) is used as the hydrologic model for the study since it incorporates detailed physical process representation, uses physical parameterization without the need for calibration and can be run at relatively high spatial and temporal resolutions.
