Indonesia is a tropical country with abundant water resources consisting of rivers, lakes, dams, swamps and flood plains. High pressure on these natural resources, mostly related to anthropogenic activities and climate change, tend to increase environmental degradation and water ecosystem deterioration. Various possible efforts need to be considered in order to overcome water related problems in the future. Ecohydrology application will be a useful tool in regulating water circulation, eroded soil transportation, water quality, quantity and availability, and floods and drought risk. Implementation of ecohydrological concept at demonstration site scale in a tributary of the Saguling reservoir catchment, the upper Citarum watershed, Indonesia aims to facilitate different part of stakeholders to have best practices tools and field experiences in dealing with daily water ecosystem and environmental challenges. This study showed a very high erosion at internal demonstration site area, closely related to increase of river water turbidity. Meanwhile, developed modelling system may predict water and sediment yields, soil erosion and deposition sources in good performance, either within the demonstration site or the entire area of upper Citarum watershed. Phytoremediation ponds constructed in the demosite demonstrated their ability to improve water quality through turbidity reduction up to 64%, 76%, 68%, 92%, and 88%, for Lemna, Landoltia, Salvinia, Pistia, and Eichhornia respectively. Understanding and taking into account community characteristics will greatly assist ecohydrology concept implementation around ecohydrology demonstration site in Saguling catchment area.

印度尼西亚是一个热带国家，拥有丰富的水资源，包括河流、湖泊、水坝、沼泽和洪泛平原。这些自然资源面临的高压，主要与人为活动和气候变化有关，往往会加剧环境退化和水生态系统恶化。需要考虑各种可能的努力，以解决未来与水有关的问题。生态水文应用将成为调节水循环、侵蚀土壤运输、水质、数量和可用性以及洪水和干旱风险的有用工具。在萨古林水库集水区支流、上西塔鲁姆流域的示范点规模实施生态水文概念，印度尼西亚旨在促进不同部分的利益相关者在应对日常水生态系统和环境挑战方面拥有最佳实践工具和实地经验。本研究表明，内部示范场地区域的侵蚀非常高，与河水浊度的增加密切相关。同时，开发的建模系统可以在示范点内或上Citarum 流域的整个区域内对水和泥沙产量、土壤侵蚀和沉积源进行良好的预测。在示范区建造的植物修复池展示了它们通过将浊度降低多达 64%、76%、68%、92% 和 88% 来改善水质的能力，对于 与河水浊度增加密切相关。同时，开发的建模系统可以在示范点内或上Citarum 流域的整个区域内对水和泥沙产量、土壤侵蚀和沉积源进行良好的预测。在示范区建造的植物修复池展示了它们通过将浊度降低多达 64%、76%、68%、92% 和 88% 来改善水质的能力，对于 与河水浊度增加密切相关。同时，开发的建模系统可以在示范点内或上Citarum 流域的整个区域内对水和泥沙产量、土壤侵蚀和沉积源进行良好的预测。在示范区建造的植物修复池展示了它们通过将浊度降低多达 64%、76%、68%、92% 和 88% 来改善水质的能力，对于分别是 Lemna、Landoltia、Salvinia、Pistia和Eichhornia。了解并考虑社区特征，将极大地有助于萨古岭流域生态水文示范点周边生态水文概念的实施。
