2. Methods

2.1. Overview of study approach

The overall analytical framework consists of land-use change modeling, development of climate change scenarios, and modeling of water, nutrient and sediment dynamics in a watershed. We simulated future land-use patterns using the Conversion of Land Use and its Effects (CLUE) model, which is based on logistic regression models and has driving factors including spatial policies and land-use demand. We developed the multiple climate change scenarios generated by a general circulation model (GCM) for the study watershed. Following the development of change scenarios for land use and climate, we applied the Soil Water and assessment Tool (SWAT) to simulate water, nitrogen, phosphorus, and sediment dynamics under multiple land-use and climate change scenarios at the watershed scale. We then analyzed relationships between hydrologic and water quality components to test the hypothesis that future land-use and climate changes will impact yields of water, sediment, nitrogen, and phosphorus in the watershed.
