The research community over the past several years has put a great effort into studying the potential impacts of a changing climate. But the issues that face the world today encompass greater change than just that of climate. For instance, there are changes due to population dynamics (such as migration), economics, and the way that land is used. Water resources are affected specifically by changes in climate and land use. A water balance model developed for the purpose of examining climate change was extended to allow analysis of impacts from land-use change. In addition, it was modified so that a watershed could be modeled by multiple smaller units within the basin. Two methodologies were applied to break the basin into smaller parts: first, hydrologic boundaries of major tributaries were used, and second, a delineation based on five classes of land-use type, which included tundra, forest, rangeland, agriculture, and urban land, was created. The model originally had three parameters w.
