“…Ma, et al (2020) [11] optimized the early FLWL with full consideration of the characteristics of flood season staging, realized the balance of the comprehensive benefits of flood control and power generation and fish spawning, and provided technical support for ecological environmental protection. In Li, et al (2022) [12], based on the staging results considering risk and benefit indicators, the FLWL selection scheme integrating water supply and power generation and extreme risk is identified, which lays a scientific foundation for further improving the benefits of water supply and power generation.…”

Setting the staged flood limit water level (FLWL) through flood season staging is an important means of fully utilizing reservoir flood resources. The widely-used Fisher optimal partition method requires a certain time domain as the basic unit in determining the optimal staging of a flood season. Currently, 5 and 10 days matching the month and solar terms are usually used as the time unit. This study aimed to analyze the influence of other time-domain units (7 and 15 days) that meet the relevant requirements on the staging results and to provide a scientific basis for the selection of time-domain units in flood season staging. The rationality of the staging scheme was tested using the improved Cunderlik method, and the influence of specific basic units in the Fisher optimal partition method on the staging results was evaluated. The highest relative superiority of 0.9876 was found for 5 d, indicating that this is a suitable time-domain unit. The optimal staging result was determined as 20 June for the first segmentation point and 20 August for the second. A comparison of the staged FLWL with a single fixed FLWL showed that the water level was raised by 1.56 m in the pre-flood season, 0.65 m in the main flood season, and 1.37 m in the post-flood season. Water storage increased by 12.79 million m3 during the flood season, effectively alleviating the mismatch between water supply and storage.

“…In order to maintain flood control during the flood season, reservoir water levels are generally not permitted to exceed the FLWL. In the past, many authors have studied this matter (Wu & Ping 2018;Xie et al 2018;Li et al 2022). The effects of reservoir operation on flood inundation in the Vu Gia Thu Bon basin were investigated by To et al (2022).…”

This paper proposes to optimise the operation of the A Vuong reservoir using the dynamic programming technique. The A Vuong is a large reservoir in Vietnam serving multiple purposes, including power generation, flood control, and downstream water supply. First, different flood control storage capacities (Vpl) are investigated, and the best one is chosen based on the criteria of power output and the reservoir's ability to fill up after each regulation cycle. That option is for Vpl to be 50, 30, and 10% of the active storage capacity in September, October, and November, respectively. The study also proposes new operating rule curves with various scenarios of different beginning water levels, ranging from 368 m to 380 m. The average lines of the operating rule curves are also suggested for easier and more efficient operation. Recommendations for using this operating rule curve, as well as its advantages compared to the current one, are also discussed. The results show that the proposed operating rule curves provide much better performance compared with the current in terms of increasing the power output, with a 3.1% increase, while also protecting other water uses.
