A long-term perspective of climate change patterns leads to the strategic management of limited water resources and consequently achieves the maximum level of social satisfaction between the various sectors in a water allocation system. Therefore, this study first adopts Soil &Water Assessment Tool (SWAT) to simulate future climate change patterns [2020–2050 and 2051–2080] under Representative Concentration Pathway (RCPs) scenarios, and then the extracted SWAT output is applied as the initial data in a bi-level programming model in which the manager of the upper level (MUL) tries to maximize the level of social satisfaction between sub-areas while the lower level manager (MLL) focuses on maximization of multi-sectoral social satisfaction. Also, historical data collected from Zayandehrud basin, Iran as a case study are considered for calibration, validation, and subsequently projecting the runoff data for mentioned periods. Based on the output related to the regional hydrological cycle under the [RCP4.5/2020–2080 & RCP8.5/2020–2080] scenarios, the study area is strongly affected by drought and relative temperature increase. Accordingly, due to the shrinkage of water resources in the basin, the highest degree of consumer satisfaction is related to the domestic sector as the smallest recipient of water resources. Thus, with the development of adaptation measures such as the use of demand reduction leverage for the effective use of limited water resources, the challenge of demand dissatisfaction for both the industrial and agricultural sectors is significantly improved.

流量不确定性下基于SWAT的双目标框架提高城市配水系统消费者满意度

气候变化模式的长期视角导致对有限水资源的战略管理,从而在水分配系统的各个部门之间实现最大程度的社会满意度。因此,本研究首先采用水土评估工具(SWAT)在代表性浓度路径(RCPs)情景下模拟未来气候变化模式[2020-2050和2051-2080],然后将提取的SWAT输出作为初始数据应用于一个双层规划模型,其中上层管理者(MUL)试图最大化子区域之间的社会满意度水平,而下层管理者(MLL)则侧重于最大化多部门社会满意度。此外,从 Zayandehrud 盆地收集的历史数据,伊朗作为案例研究被考虑用于校准、验证,并随后预测上述时期的径流数据。根据 [RCP4.5/2020–2080 & RCP8.5/2020–2080] 情景下与区域水文循环相关的输出,研究区受到干旱和相对温度升高的强烈影响。因此,由于流域水资源的萎缩,消费者满意度最高的是作为水资源最小接受者的国内部门。因此,随着适应措施的发展,例如利用减少需求杠杆有效利用有限的水资源,工业和农业部门需求不满足的挑战得到显着改善。然后预测上述时期的径流数据。根据 [RCP4.5/2020–2080 & RCP8.5/2020–2080] 情景下与区域水文循环相关的输出,研究区受到干旱和相对温度升高的强烈影响。因此,由于流域水资源的萎缩,消费者满意度最高的是作为水资源最小接受者的国内部门。因此,随着适应措施的发展,例如利用减少需求杠杆有效利用有限的水资源,工业和农业部门需求不满足的挑战得到显着改善。然后预测上述时期的径流数据。根据 [RCP4.5/2020–2080 & RCP8.5/2020–2080] 情景下与区域水文循环相关的输出,研究区受到干旱和相对温度升高的强烈影响。因此,由于流域水资源的萎缩,消费者满意度最高的是作为水资源最小接受者的国内部门。因此,随着适应措施的发展,例如利用减少需求杠杆有效利用有限的水资源,工业和农业部门需求不满足的挑战得到显着改善。5/2020-2080]情景,研究区受到干旱和相对温度升高的强烈影响。因此,由于流域水资源的萎缩,消费者满意度最高的是作为水资源最小接受者的国内部门。因此,随着适应措施的发展,例如利用减少需求杠杆有效利用有限的水资源,工业和农业部门需求不满足的挑战得到显着改善。5/2020-2080]情景,研究区受到干旱和相对温度升高的强烈影响。因此,由于流域水资源的萎缩,消费者满意度最高的是作为水资源最小接受者的国内部门。因此,随着适应措施的发展,例如利用减少需求杠杆有效利用有限的水资源,工业和农业部门需求不满足的挑战得到显着改善。
