|Abstract:||This thesis describes an aggregate model of a large agricultural watershed, developed with the specific objective of modeling the interactions between farming decisions and the quantity of sediment delivered to the receiving surface water. The purpose for developing such a model is to combine it with an economic optimization model to enable analyses to pursue minimum cost land management strategies to control sediment.
The aggregate economic model that is developed is an adaptation of an existing economic optimization model addressing the same issue of sediment control at minimum cost, but on a site-specific (i.e., disaggregate) basis. The existing site-specific model provided a relatively simple sediment transport function and an efficient economic optimization algorithm particularly appropriate for adapting to an aggregate application.
Concepts and abstractions borrowed from the field of soil landscape analysis, and the reasoning used in applying them to the aggregation of both descriptive and spatial information relating to a 31,000 acre watershed are described. Numerous investigations of the validity of the aggregation approach are described and discussed. And, finally, the usefulness of the aggregate model is demonstrated with some applications.
