Part of: Water Policy and Management: Solving the Problems

Abstract:

Mathematical models based on nonlinear programming are developed for operating soil aquifer treatment(SAT) systems. The objective of these optimization models is to determine the operation policy (loading schedules) that maximizes the infiltration volume subject to constraints for physical and biological processes of infiltration (Green-Ampt model and an empirical model considering surface clogging effect), soil moisture redistribution (kinematic wave model), and pollutant removal. This new methodology attempts to combine the infiltration processes with the nitrogen removal process in the operation of SAT system.
