| description | Study region: Xinjiang is a typical arid and semi-arid region in China, where concurrent regional water shortage and seasonal flooding pose tremendous challenges for regional water resources management. Seasonal flash floods due to heavy rainfall and snowmelt processes necessitate reservoir regulations in arid regions, whereas previous studies have focused mainly on humid regions. Study focus: Taking the TouTun Reservoir in Xinjiang as a case study, we formulated flooding regulation protocols with the aim to reduce flood disasters and optimize water resources use. Different from traditional static flooding regulations, here we proposed and validated a dynamic potential flood stage by subdividing the flood seasons into three intervals: pre-flood, main flood, and post-flood. We used an improved pre-release constraint algorithm, such as the long-short-series mean correction method, and evaluated the flood stage potential during the aforementioned three intervals. New hydrological insight for the region: We detected that at the design flood frequency of 0.1 %, the peak flood flow during the main flood season reached 835 m3/s. We set the dynamic stage flood potential between 986.45 m and 989.13 m during the main flood season and ensured an additional 4.93 × 106 m3 of available reservoir capacity to avoid flood disasters. By dynamic flood stage potential controlling algorithm, we reduced the peak flood stage level 35.84 % and lowered the peak floodwater level by 0.54 m, and significantly alleviating flood risks and improving water supply stability. The findings of this study can provide practical reference for floodwater control of other arid and semiarid regions over the globe. |
