有几个问题影响着河流流域的水资源可持续性。其中包括社会、经济和环境方面。然而，它们往往被分开处理，而不是作为一个综合的动态过程。为了将水文、环境、生活和政策问题以及现有的压力和政策响应整合到一个定量、动态和综合的指标中，本文提出了一个基于压力-状态-响应函数的流域可持续性指数（WSI）。将其应用于巴西一个2，200平方公里的联合国教科文组织-地球环境、生命和政策示范流域（SF Verdadeiro），获得的WSI值为0.65，代表流域可持续性的中等水平。
Several issues impact the water sustainability of a river basin. Among them are the social, economic, and environmental aspects. However, they are often treated separately, and not as an integrated, dynamic process. In order to integrate the hydrologic, environmental, life and policy issues, as well as the existing pressures and policy responses in one quantitative, dynamic, and aggregated indicator, a watershed sustainability index (WSI), which uses a pressure-state-response function, was developed and is proposed in this paper. Applied to a 2,200 km(2) Unesco-HELP demonstration basin in Brazil (SF Verdadeiro), the value obtained for WSI was 0.65, which represents an intermediate level of basin sustainability.
