The Portuguese Institute for Water (INAG) is the sectorial agency with majors responsibilities for water planning and management the national level. The attributions of INAG are:

The Water Resources Department is responsible for legal attributions within the Institute of Water, for the development, implementation and co-ordination of the water-related national activities such as data acquisition of several hydrological and water quality monitoring networks and the development and maintenance of the Portuguese Water Resources Information System - SNIRH. The activities undertaken are carried out for surface and groundwater, and both for water quality and quantity.

The Portuguese Water Resources Information System (SNIRH) is an integrated system that processes, validates and stores hydrometeorological data plus other water resources relevant information such as water quality (both on internal and coasted water), piezometric data, stored volumes on reservoirs and water uses. This System also couples to the integration of simulation models with Geographic Information System (GIS). Connected with the adequate models, the system allows for real time flood and pollution accidents warning systems fed by the telemetric monitoring network. In association to the system, a set of kits for pre and past-processing of based data aiming to deliver information to the public in a more friendly way: possibility of elaboration of reports, tables and graphs, statistical handling of the information, among others.

Available through the Internet, SNIRH is a tool for the public use, where is possible to obtain:

INAG carries out application projects in the fields of information systems, hydrology, hydraulics and hydrogeology (mainly rainfall-runoff modelling, flood forecasting, drought analysis, groundwater quantity and quality assessment) and water resources planning and management (namely hydrografic basin plans, national water plan and problems liked to transboundary watercourses). Most of these tasks are accomplished in co-operation with national research institutes and universities and with other European countries.
