New management approaches are needed to improve cooperation among independent water resources users and stakeholders. This is because cooperation is not naturally incentivized – actions beneficial to upstream users often negatively impact users downstream. This makes it difficult to foster cooperation over water withdrawal rights, water quality responsibilities, and risks associated with flooding.
Historically, cooperative agreements among independent entities have required static legal agreements that create barriers to adaptation or policy improvement. This new research, funded by the National Science Foundation, will explore novel management approaches, such as market-based mechanisms, to overcome these cooperation challenges, based on game theoretic models they will develop and use.
The researchers anticipate that the approaches’ efficiency and equity gains will benefit municipal, industrial and agricultural water users; treatment plant and network operators; and the natural environment. The Anacostia River testbed will focus on urban river restoration, while the Duck River testbed will emphasize economic development and ecological preservation.
Professors from University of Maryland Brubaker will use rigorous mathematical techniques to model deterministic and stochastic water infrastructure systems from a one-level and two-level equilibrium problem perspective based on non-cooperative game theory. The developed models will combine engineering, water policy, machine learning, risk analysis, resilience planning and economic elements.
The project will account for risk and benefits in a systematic, unified, and endogenous manner across all entities and their interactions and will allow the system operator/regulator to effectively balance risk and cost under uncertain and/or changing conditions.
The researchers also anticipate the work will lead to algorithmic advances in decomposition methods for water equilibrium problems as well as stochastic equilibrium models for this general class of infrastructure equilibrium problems. A rolling-horizon, stochastic mathematical program with equilibrium constraints will develop strategic learning algorithms for water stakeholders to improve their decision-making over time.
