Genetic Algorithm-Based Model For Determination Of Efficient Management Strategies For Irrigation Canal Networks, Talaat Taher El Gamel
Civil & Environmental Engineering Theses & Dissertations
An optimization model for the determination of efficient management strategies for an irrigation canal network is developed. The objective is to minimize the total water consumed while satisfying various system constraints. An unsteady flow model is used to simulate the flow in the network. A genetic algorithm- (GA-) based framework is used to solve the model. The suitable GA parameters that should be used within the model, as well as the performance of various constraint-handling techniques, are studied. Uncertainties in crop pattern and water consumption rates are incorporated into the search procedure to identify more reliable solutions. A graphical interface …

Determining Pesticide Persistence On Plastic Mulches Used As Row Covers In Tennessee, William Tod Pinson
Masters Theses
During the past decade, the use of plasticulture production systems has become an increasingly common practice for vegetable production in the United States. The plasticulture system is the use of plastic mulch to serve as a row cover in the field. The semi-permeable material can be made of varying densities of polyethylene, and serves as a barrier that helps maintain soil moisture and reduce weed growth. Increased use of these plastics has created a waste management problem, as producers have difficulties trying to find the best and cheapest disposal method. A few companies had begun collecting the materials for reprocessing …
