Implementing environmental flows in complex water resource systems:the Rio Chama, New Mexico, USA
Managing our water resources requires balancing of the economic, environmental, and social needs of the basin. It is difficult capture the impact of environmental flow alternatives on each of these components using traditional deterministic modeling approaches. System dynamics modeling offers a method of assessing the connections between economic, environmental, and social components of a basin and the impacts of flow alternatives on these components. Given the benefits of using a system dynamics modeling approach, our objective was to develop and demonstrate a stochastic system dynamics modeling framework to evaluate environmental flow alternatives. Specifically, our research examined the influence of flow alternatives on cottonwood recruitment and reservoir storage within the Rio Chama basin, New Mexico, US. We used the ―recruitment box model‖ to evaluate the impact of three alternatives on cottonwood recruitment within the project reach. We also show that alternatives can be evaluated using comparative metrics, which allow managers to more easily employ an adaptive management strategy for incorporating environmental flows into existing operations.
