了解可用资源和使用这些资源的人的需求对于评估和分配水资源是必要的。利用流域水资源的主要部门是农业,饮用水,畜牧业,和工业,在这些不同的活动部门之间分配水资源的有效和合理管理至关重要。本研究试图通过采用情景分析方法结合水评估和规划模型(WEAP)来分析2015年至2050年之间的用水趋势和预期需求,为Dhasan河流域(DRB)开发综合水资源管理系统,模拟五种可能的情景(I,II,III,IV,和V)至于外部驱动因素。对于WEAP建模框架,选择2015年作为当前(基准)年,将所有可用信息和输入数据提供给模型,并分析了2016-2050年(预测期)的未来需求状况。从调查结果来看,据观察,在预测期内,总需水量,未满足的需求,流量分别为185.29Bm3、117.35Bm3和58.26Bm3,在情景I的情况下;在情景II的情况下,232.34Bm3,162.17Bm3和59.87Bm3;在情景III的情况下,为139.40Bm3,84.37Bm3和58.15Bm3;在情景IV的情况下,为186.15Bm3,118.76Bm3和56.98Bm3;和181.89Bm3,96.87Bm3和53.11B工业发展,农业面积的增加将大大增加水的需求,对环境和人类构成威胁。因此,实施改进的灌溉技术,推进农场的农业实践,建造节水和保留结构可以显着减少DRB中未满足的需求和不足。总体调查结果表明,未来达哈桑水资源的压力将会增加,因此,已经提供了一些建议,以协助决策者进行水资源的可持续规划和管理,以满足未来的需求。
Understanding the available resources and the needs of those who use them is necessary for the evaluation and allocation of water resources. The main sectors utilizing the basin water resources are agriculture, drinking water, animal husbandry, and industries, and the efficient and rational management of water resources to be distributed among those different sectors of activity is vital. This study attempts to develop an integrated water resource management system for the Dhasan River Basin (DRB) by employing a scenario analysis approach in conjunction with Water Evaluation and Planning Model (WEAP) to analyze trends in water use and anticipated demand between 2015 and 2050, simulating five possible scenarios (I, II, III, IV, and V) as for external driving factors. For the WEAP modeling framework, 2015 was chosen as a current (base) year for which all available information and input data were given to the model and the future demand situation was analyzed for the period 2016-2050 (forecasting period). From the findings, it was observed that for the forecasting period, total water demand, unmet demand, and streamflow were 185.29 Bm3, 117.35 Bm3, and 58.26 Bm3, respectively, in the case of scenario I; 232.34 Bm3, 162.17 Bm3, and 59.87 Bm3 in case of scenario II; 139.40 Bm3, 84.37 Bm3, and 58.15 Bm3 in case of scenario III; 186.15 Bm3, 118.76 Bm3, and 56.98 Bm3 in case of scenario IV; and 181.89 Bm3, 96.87 Bm3, and 53.11 Bm3 in case of scenario V. Results of the study indicated that by 2050, increasing population growth, industrial development, and an increase in the agricultural area will rise the water demand dramatically, posing threats to the environment and humans. Therefore, implementing improved irrigation technologies, advancing agricultural practices on farms, and constructing water conservation and retaining structures could significantly reduce the unmet demands and shortfalls in DRB. Overall findings reveal that the pressure on the Dhasan water resources would increase in the future, and thus several suggestions have been provided to assist decision-makers in sustainable planning and management of water resources to meet future demands.
