Abstract: The implementation of sustainable development principles in water resources management refers to an integrated management and coordination of the entirety of the actions and interventions that concern the water ecosystem, or parts of it, within a watershed. This procedure is accomplished through the development and application of an overall management plan at a hydrological basin level. This concept was followed by the water resources management plan of the city of Volos’ watershed, which is presented in this paper. The main objective is the choice of the best set, among others, of hydraulic projects, which will be able to re-establish the balance in the basin’s deficient water budget, satisfying at the same time future urban water demand. Decision making was carried out using a GIS tool and involved traditional water capture hydraulic projects on the one hand and sustainable water saving measures on the other. The whole procedure is being developed in an area with serious environmental problems, concerning mainly the groundwater resources. The particularity here is that the alternative solutions strongly depend on administrative agreement and consensus between relevant authorities.

摘要：水资源管理中可持续发展原则的实现指的是：在一个流域内，针对人类对水生态系统的影响进行综合管理和协调。这需要在整个流域层面上进行整体管理。本文详细介绍了希腊沃洛斯流域如何应用这一理念进行水资源管理规划。水资源管理可持续框架的目标是选择有合适的水资源配置工程，在水资源缺乏地区重新建立起供需均衡，同时满足未来用水需求。制定该框架需要做两方面工作：一是利用GIS平台调度传统水资源配置工程，二是采取需水管理措施节约用水。案例所在地的环境遭受严重污染，主要是地下水资源，其特点是很大程度上依赖于政府间达成协议以及相关部门之间的共识。
