综合水管理旨在平衡多个利益相关者的利益，这些利益相关者希望在机构和法规的范围内实现水的多种最终用途。这个问题在跨界和缺水流域尤其复杂。在格兰德河/布拉沃河的大弯地区，干旱的季风气候与多种人类和环境用水需求以及既定条约要求相结合，对可用水资源造成压力。我们分析了流域内的水库运行策略，使用线性规划模型将环境流量（EF）考虑因素纳入现有管理目标中，以评估水库运行策略。对五种潜在的 EF 制度进行了评估，以改善大弯地区的水生和河岸栖息地。该模型使用河流流入的历史水文记录、防洪数据和两国水分配要求以及人类需求和基础设施的参数；比较 Luis L. Leon 水库当前和优化运行的多个目标。结果表明，每月水库蓄水量的替代运营政策（与历史值相比）可以增加EF分配，而不影响供水或条约分配。然而，在管理水库的EF和防洪方面可能存在一些权衡。我们的方法为缺水流域的管理策略提供了信息，旨在将环境目标纳入现有的基础设施和运营中。
Integrated water management seeks to balance the interests of multiple stakeholders who desire many end-uses for water within the context of institutions and regulations. This problem is particularly complex in transboundary and water-scarce basins. In the Big Bend region of the Rio Grande/Bravo, an arid, monsoonal climate combines with multiple human and environmental water demands and established treaty requirements to stress available water resources. We analyzed reservoir operation strategies in the basin to integrate environmental flow (EF) considerations into existing management objectives using a linear programming model to assess reservoir operation policies. Five potential EF regimes are evaluated for improving aquatic and riparian habitat in the Big Bend region. The model uses the historical hydrologic record of river inflows, data for flood control and bi-national water allocation requirements, and parameters for human demands and infrastructure; to compare current and optimized operations of Luis L. Leon reservoir for multiple objectives. Results indicate that alternative operational policies for monthly reservoir storage (compared to historic values) can increase EF allocations without affecting water deliveries or treaty allocations. Some tradeoffs may exist, however, in managing reservoirs for both EFs and flood control. Our approach informs management strategies for the water-stressed basin that seek to incorporate environmental goals into existing infrastructure and operations.
