The sustainable management of water resources and a reliable supply of safe drinking water will play a key role for the human prosperity in the following decades. This paper presents an optimal control approach for the management of water resources in a rapid developing region with critical water shortage. A model of the water allocation system is developed which considers both surface and groundwater resources and the distribution network. A reduced model of the complex spatially distributed 3D Finite Element groundwater model is applied. Hence the optimization problem, which is formulated as a large scale structured non-linear programming problem, can be solved with appropriate computation effort. The performance of the proposed concept is analyzed using realistic optimization scenarios.Zusammenfassung Das nachhaltige Management von Wasserressourcen und die gesicherte Versorgung mit Trinkwasser wird in den nächsten Jahren weiter an Bedeutung gewinnen. In diesem Beitrag wird ein Konzept zum Management der Wasserressourcen in einer sich schnell entwickenden Metropole mit starker Wasserknappheit vorgestellt, das auf einem modellbasierten Optimalsteuerungsansatz basiert. Es wird ein Modell der Wasserressourcen (Grund-und Oberflächenwasser) und des Verteilungssystems entwickelt. Eine Besonderheit dabei ist die Berücksichtigung des räumlich verteilten Grundwassersystems. Es wird ein komplexes 3D Finite-Elemente-Modell mittels einem trajektorienbasierten Ansatz so weit reduziert, dass das Optimierungsproblem, das als hochdimensionales, strukturiertes nichtlineares Programm formuliert ist, in angemessener Rechenzeit gelöst werden kann. Die Leistungsfähigkeit des vorgeschlagenen Management-Konzeptes wird anhand realitätsnaher Optimierungsszenarien demonstriert.
Sustainable management of water resources and a safe supply of drinking water will play a key role for the development of the human prosperity in the following decades. This paper presents an optimal control approach for the management of the total water resources in a fast developing region under a critical water shortage. A model of the water allocation system is developed which considers both surface and groundwater resources and the distribution network. The spatially distributed groundwater model is considered as a reduced model of the complex 3D Finite Element model. Hence the optimization problem, which is formulated as large scale structured non-linear programming problem, can be solved in an appropriate computation time. The performance of the proposed concept is demonstrated by close to reality optimization scenarios
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
