1	Stochastic Prediction of Sediment Yields from Strip Mine Spoils of the Arid Southwest Auernhamer, Mark E., Fogel, Martin M., Hekman, Louis H., Jr., Thames, John L. 16 April 1977 (has links) From the Proceedings of the 1977 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - April 15-16, 1977, Las Vegas, Nevada / Mathematical simulation of the erosion process is accomplished by using a time series of hydrologic parameters as inputs into a modified form of the Universal Soil Loss Equation. A parameter to account for antecedent moisture conditions was found to improve the predictive success of the Universal Soil Loss Equation. The simulation predicts sediment yield resulting from a stochastic sequence of precipitation events on an experimental watershed. This sediment model will be used as a component in a larger, more complex hydrologic simulation model which can be used to determine optimum reclamation practices for the strip mined areas of the arid Southwest. Data from regraded strip mine spoils at the Black Mesa of Arizona are used in calibrating the model. Hydrology -- Arizona. Water resources development -- Arizona. Hydrology -- Southwestern states.
