Methodological note
Definition of concepts
- Hydrographical basin
- Set of slopes that incline towards a single flow of water.
- Reservoir
- Large artificial lake that is formed by interrupting the flow of a river or by creating a lake by means of a large dam.
Methodological aspects
The Catalan Water Agency (ACA) manages and plans the water cycle, with a vision of integrated water systems, taking into account the balance of all ecosystems. Water becomes a basic structural and functional element to the environment and life. This management must be compatible with the growing demand for permanence, universality and immediacy of the citizens of an advanced society, and ensure quality and good service.
The hydrology section includes fluvial systems. The fluvial systems are distributed by basins. The data refers to the volume of water contributed by rivers at different observation points (gauging stations). As for reservoirs, the volume of water stored per season is recorded. Series tables complement the information to enable comparability.
