ABSTRACT
The Wilderness Use Simulation Model (WUSM) has been modified to predict patterns of river recreation use occurring under a variety of conditions and was tested on the Green and Yampa rivers in Dinosaur National Monument. This "base-case" simulation and actual patterns of use and encounters were compared to test the simulator's validity and were found to be in close agreement. A variety of scenarios, such as changing daily entry rates and opening and closing campgrounds were simulated and produced significant changes in rates of encounters on the river and at campsites.
