GIS maps describing topography, land use and cover, soils, rainfall, and meteorological variables may become model parameters or inputs in the simulation of hydrologic processes.

This chapter identifies a scaling relationship of the drainage network derived at one resolution to those obtained at larger resolutions. Implicit in the discharge-scaling relationship is the fractal dimension of the drainage network.

Given the many surface generation utilities available within general purpose GIS packages such as ArcView or GRASS, it is important to understand how these surfaces are generated and some of the pitfalls. Figure 3.1 shows the hillslope shaded image of the
