Groundwater optimization handbook: Flow, contaminant transport and conjunctive management

This how-to book presents a thorough introduction to groundwater systems analysis and appropriate simulation optimization (S/O) approaches for several types of groundwater problems. It covers optimization terminology, principles, and S/O computational approaches and introduces optimization theory and algorithms that have been successful in resolving water quality and groundwater management problems. The author offers guidance for simplifying and solving optimization problems with selected S/O approaches and models by offering case studies, flowcharts, and numerous examples. A dictionary of terminology and access to free software is also included.
