Water delivery management in China’s irrigation districts has traditionally prioritized the main canal system, often overlooking water-saving potential of final canals and field irrigation, which offer substantial opportunities to enhance water use efficiency conserve agricultural resources. This study summarizes defines integrated as terminal management. An optimization method was developed improve management, includes optimizing quotas based on balance scheduling minimize seepage losses. A genetic algorithm employed solve problem. The applied Hongjin district Jiangsu Province, China. In 2020, paddy observed, revealing that amount for organic traditional rice 1113 mm 956 mm, respectively. Conventional practices have led extensive drainage, significant rainwater wastage, inefficient use. optimized resulted savings 302.5 325.9 respectively, compared 2020 monitored data. event early August during a 75% hydrological frequency year selected an example. With conventional scheduling, reduced losses from 6.3% 4.6%, shortened time 17 h 14 h, stabilized flow rates. proposed is valuable tool enhancing supporting better decisions districts.

Water scarcity is commonly evaluated using the water resource stress index (WRSI). However, conventional WRSI model cannot effectively reflect shortage in humid areas, which may lead to distorted evaluation results. To solve this problem, an improved has been designed. In WRSI, assessment year first divided into multiple periods. Then, temporal (T-WRSI) built evaluate each period. Finally, comprehensive (C-WRSI) constructed based on entropy weight (EWM) synthetically assess condition. The of Yongzhou City taken as a sample for evaluation. results are follows. (i) Lingling-Lengshuitan District and Dong’an County suffer from most serious shortage. Their C-WRSI values 0.464 0.458, respectively, both “high” grades. (ii) T-WRSI more than 0.4 August October indicating that major key period October. (iii) reasons annual runoff distribution uneven with uniformity coefficient (Cv) 0.83, main irrigation periods coincidentally accompanied by retreat rainfall. (iv) measures strengthen management, optimize plant structure, construct reservoirs. (v) calculated region 95–168% larger those WRSI. better capacities evaluating induced within identifying regions.
