Many of the larger reservoirs and water projects located in the Sierra Nevada are operated for multiple uses, such as water supply, hydropower, flood control, environmental mitigation, and recreation.
Most large plants serve multiple purposes: hydropower generation, flood control, storage of drinking water, and the impounding of water for irrigation.
Located near Gilbertsville and 22 miles (35 km) upstream from Paducah, it regulates the flow from the Tennessee River into the Ohio River for navigation, hydropower, and flood control.
In the eastern US, frequencies of both high and low streamflow were projected to increase in the majority of subbasins upstream of both hydropower and flood control reservoirs.
As a result, a simulation-based optimization model was proposed to maximize multiple benefits, such as flood control, hydropower generation and navigation.
The optimal designed seasonal FLWL scheme involves tradeoffs among flood control, hydropower generation and navigation, and enhancement of the economic benefits without increasing the flood risk.
Alternatives are characterized by 10 attributes, namely flood control, hydropower, recreation, Missouri River navigation, water supply, fish and wildlife, interior drainage, groundwater, historic properties and Mississippi River navigation.
Nonetheless, the Mekong River Basin is changing rapidly due to accelerating water infrastructure development (hydropower, irrigation, flood control, and water supply) and climate change, bringing considerable modifications to the flood pulse of the Tonle Sap Lake in the foreseeable future.
Optimal refill operation before the end of flood season is a valuable and effective approach to compromise the flood control, hydropower generation and comprehensive utilization of water resources of river basins.
Liu et al. (2015) proposed a simulation-based optimization model to develop seasonal' Flood Limited Water Level Scheme' involving trade offs among flood control, hydropower generation and navigation and enhancement of the economic benefits without increasing the flood risk for China's Three Gorges Reservoir.
