dc.description.abstractThis thesis presents a comprehensive model for predicting storm runoff and contributing areas based on precipitation and topography. Independent storms are defined using a procedure by Restrepo-Posada and Eagleson (1982) and stormflow is defined with geochemistry. Recursive digital filters are compared and calibrated to geochemical hydrograph separation on Panola Mountain Research Watershed enabling the digital filters to be used to define stormflow on Coweeta Watershed 18. High resolution topography of the watersheds, derived from LiDAR, is used to extract dense drainage networks. The networks predict surface runoff flow paths and the areas of a watershed that produce runoff. The mean lengths of streams of the networks are used to parameterize the geomorphologic instantaneous unit hydrograph that is used to model storm hydrographs. Finally, modeled storm hydrographs are compared to observed and digitally filtered stormflow. Comparison of observed and modeled storms determines if this model is suitable for ungauged basins.
