摘要

水资源短缺对东帝汶帝力生活的各个方面都有影响。为了支持政府在水资源领域的愿景和计划,开展了水资源管理战略制定研究。优先战略的结果是发展水资源基础设施以满足城市用水需求。该战略的一个行动计划是建设水库基础设施。本研究的目的是评价在帝力建设小型或大型水库以满足水的需求。采用放水标准操作规则法模拟模型,通过对水库可靠性和库容的分析,对Beemos河和Becora河水库开发战略实施方案进行评价。水平衡模拟结果表明,由于水库容量有限,Beemos和Becora两个小水库的清洁水服务可靠性不能达到100%。大型Beemos水库容量优化结果表明,其入库潜力可利用率达90%,可满足2030年前城市用水需求。虽然模拟结果显示了良好的指示性,但政府在实施之前仍必须在上游地区进行详细的可行性研究。可以建议在水资源开发中实施大型水库的开发,以满足帝力的用水需求,因此可以支持东帝汶在水部门的目标或愿景,以及在清洁水和卫生部门的可持续发展目标。

Evaluation of Reservoir Capacity and Reliability for urban water purpose in Dili, Timor Leste
Water shortages has an impact on all aspects of life in Dili, Timor Leste. To support the government vision and program in water sector, a study on the developing of water resource management strategies has been carried out. The priority strategy has resulted that is developing water resource infrastructure to meet urban water demand. One action plan of this strategy is to build reservoir infrastructure. The purpose of this study is to evaluate the construction of small or large reservoir to meet the water demand in Dili. Evaluation of the strategy implementation plan of the reservoirs development in the Beemos and Becora Rivers through analysis of the reliability and capacity of the reservoir using a simulation model of water release standard operating rules method. Water balance simulation results show that the reliability of clean water services from the two small reservoirs of Beemos and Becora cannot reach 100%, due to the limited capacity of the reservoir. The results of capacity optimization of large Beemos Reservoir show that the potential for inflow can be utilized 90%, therefore it can meet urban water demand until 2030. Although the simulation results show a good indication, the government still must carry out a detailed feasibility study in the upstream area before it is implemented. The developing of large reservoir can be recommended for implemented in the development of water resources to meet water demand in Dili therefore can support the Timor Leste's targets or vision in the water sector and the Sustainable Development Goals in the clean water and sanitation sector.
