Description:
This report provides a user manual for the hydrologic, nonpoint source pollution simulation of the generalized planning model for evaluating forest and farming management alternatives. The manual contains an explanation of application of specific code and indicates changes that should be considered when applying the simulation to different watersheds. Two example applications of the model are included to illustrate model sensitivity to management alternatives. A timber harvest example composes the undisturbed watershed with clear-cut logging with balloon, high lead, and tractor transport. A grazing activity example compares rotation and heavy continuous grazing alternatives. The manual appendices contain all program listings and job control language for the CDC CYBER 172.
