“…There is a sharp contradiction between the supply and demand of water resources in many countries because of their uneven spatial and temporal distributions [1][2][3]. Numerous open channels with cascade pumping stations have been constructed as a solution to this problem [4][5][6]. However, improper control of these cascade pumping stations may cause channel overflow, drying up of the pumping station forebay, low pumping efficiency, and even some catastrophic events, such as pumping unit vibration and channel lining damage.…”

For an open channel with cascade pumping stations, the water level immediately upstream of the pumping station should be kept constant to ensure pumping stability and lining safety. In this study, a simple method was proposed to determine the control time of the pumping station to ensure a stable water level immediately upstream of the pumping station using reverse analysis. The variable discharge process and fixed water level were taken as the upstream and downstream boundaries of the one-dimensional open channel hydrodynamic model, and the discharge process of the pumping station was obtained under ideal conditions. The control time was determined by the equivalent water volume change considering the step change of the discharge of the pumping station. A case study was performed using the Jiaodong water diversion project from Songzhuang sluice to Huibu pumping station (G1–P1), and the effects of the initial discharge, variable discharge, and downstream water level on the control time were investigated. The results show that (1) the larger the initial discharge, the shorter the control time; (2) increasing the upstream discharge reduced the control time, while decreasing the upstream discharge increased the control time; (3) the control time decreased with the increase of the water depth immediately upstream of the pumping station.

“…Many studies have addressed the issue of reservoir operation under combined NI and CI (Cabo et al, 2014; Guo et al, 2012; Ming et al, 2017; Peng et al, 2014; Xi et al, 2010; Zhu et al, 2014). For example, Zhu et al (2014) developed a nonlinear optimization model to minimize the water shortage and water diversion under different hydrological conditions.…”

Interbasin water transfers have been undertaken in those regions that water demand has gone beyond regional water availability. Some reservoirs in a recipient region have both natural inflow (NI) and the controlled inflow (CI) through water transfer. This study establishes a theoretical framework to analyze reservoir operation with combined NI and CI, via an optimization model to maximize the net benefit of reservoir operation, considering both deterministic and stochastic NI. Operation rules for both water transfer and reservoir release are derived from the framework. It is illustrated that the amount of CI depends on water availability to the recipient reservoir, the relationship between marginal benefit and marginal cost, the water transfer capacity, and the uncertainty level of NI. As forecast uncertainty increases, more water is transferred, and more water is left in the reservoir as carryover storage when the initial water availability (WA0) is small; however, with a certain high level of WA0 and forecast uncertainty, water transfer will be controlled to reduce the risk of water abandonment. Notably, the critical values of the forecast uncertainty that control water transfer are identified under the various WA0. The analysis is illustrated via a case study with a real‐world reservoir in northeastern China. In summary, this study derives hedging rules for water supply reservoir with combined NI and CI to mitigate the risk of both water shortage and water abandonment and provides guidelines to use NI forecasts for water transfer and reservoir release decisions.

“…The basic principle of this approach is to simulate future performance of a system over a set of emission scenarios. Most previous studies of the potential impacts of climate change on IBWT have used these scenario-led approaches (Xi et al, 2010;Gurung and Bharati, 2012;Maknoon et al, 2012). These top-down methods project future conditions from downscaled oceanatmosphere general circulation models (GCMs) and simulate system responses using hydrological models.…”
