Technical terms
Short explanations of selected technical concepts commonly used in hydrogeology, hydrology, modeling and geoinformatics studies.
Aquifer
A geological unit that can store and transmit groundwater.
Water balance
The joint evaluation of water inputs, outputs and storage changes within a system.
Streamflow transposition
The adaptation of flow data from a gauging station to another location by considering comparable basin conditions.
Basin
A topographic area where surface runoff drains toward a common outlet.
Drainage network
The system formed by streams, channels and surface runoff pathways within an area.
Flood analysis
The evaluation of flood potential based on rainfall, runoff, basin characteristics and channel conditions.
Dewatering
Technical measures used to control groundwater level or inflow in excavation, mining or construction areas.
Impact area
The area where hydrological or hydrogeological conditions may change due to an activity, abstraction, drainage or project.
Environmental flow
The water regime that should be maintained in a river or wetland system to sustain ecosystem functions.
Hydrogeological model
A conceptual or numerical representation of a groundwater system with geological, hydraulic and boundary conditions.
Erosion susceptibility
The classification of erosion tendency based on land, slope, rainfall, soil and land-use characteristics.
Spatial analysis
The assessment of georeferenced data through mapping, database and analysis methods.
