WSM DSS is a comprehensive Decision Support System for the development of sustainable water management strategies and water resources planning in the framework of the European Directive 2000/60. It is especially dedicated to governmental agencies and stake holders who are in charge of Integrated Water Resources Management (IWRM).
The generic water resource system is schematized by a network of nodes and links whose locations are drawn using the GIS interface of WaterStrategyMan DSS. Nodes and links represent the existing (agricultural, industrial or domestic) uses, available resources, both natural (i.e. rivers, artificial reservoirs, wells) and artificial (i.e. water reuse and treatment plants), waste water treatment plants and electric energy production.
Modeling of the water system allows estimate the amount of water that is necessary to satisfy existing and future water demand, to determine which are the most urgent action to be taken (i.e.. building a new waste water treatment plant) and to appraise incidence of possible actions in economic terms.
WSM DSS has a GIS visual interface that allows schematizing the water system of the region of application. The different components are connected by a network of nodes and links that allow information exchange on water availability and water allocation. A Geo-database is used to store information on the water system.
The Water Availability Module is used to estimate the amount of available water that can be distributed to end users. Water availability evaluation includes computation of natural recharge to rivers, lakes and artificial reservoirs and groundwater. Different scenarios of future precipitations and rainfall-runoff generation can be used to estimate future water income and forecast effects of possible local or global climatic changes.
The Water Demand Module is responsible of the generation of the possible future scenarios of water demand, caused for example by an increase of domestic consumptions due to a population growth, both seasonal or permanent, by a modification of agricultural practices, by an increase of industrial production. Besides water consumption, WSM DSS considers also non-consumptive use of water, like hydroelectric energy and navigation.
