Methodological note
Definition of concepts
- Contribution of a river
- Total volume of water that flows in a year (hm³/year) past the point where the volume is measured.
- Volume of a river
- Result of multiplying the area of the section of the water flow, at a certain point, by the speed at which it moves. It is measured in cubic metres per second.
- Hydrographical basin
- Set of slopes that incline towards a single flow of water.
- Gauging station
- Point for measuring fluvial volume. The set of stations constitute a network that can be used to evaluate the total hydraulic resources.
- Surface area of the gauging station basin
- Total surface area of the receiving basin that is associated exactly with the point where the gauging station is located.
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.
Since 2010, the Garriga's gauging station has been replaced by the one at Esponella.
When the value is lower than that of the minimum unit to be able to estimate the statistical operation or if it effects statistical confidentiality, the symbol used is "..".
