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.
To propose the main objectives and strategies and define the technical,
economic and legislative measures for the implementation of water management
To promote water resources integrated planning subordinated to river basin
To promote a comprehensive coastal planning and land use management of
the littoral areas.
To promote water resources conservation in quantity and quality, including
their physical, chemical and ecological characteristics.
To develop and maintain water resources information systems, including
quantity and quality.
To develop and maintain information systems on water needs.
To promote new hydraulic schemes with social, economical and environmental
To promote monitoring and control of the existing schemes.
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.
Monthly and yearly reports on water resources.
Inventory and characterisation of reservoirs.
Relevant national water related and European community legislation.
Queries to the database loaded with monitoring networks data.
Bookstore of relevant studies and research projects undertaken by partnership
with other groups (research teams, consultants).
Map gallery of existing information grouped by the main river basins.
Relevant information about recent activities and technique guidelines for
River Basin Planning.
Thematic reference to new work, public sessions and other events of general
