Extracted water volume per hour and meter drawdown for a defined well diameter.

Boreholes chiefly penetrating the shallow subsurface, enabling detailed characterisation of layers to a maximum depth of about 500 metres.

This application "Geologically documented objects" enables the user to buy his selected data from the database of the geologically documented objects of the Czech Republic (scil. borehole database) managed by the CGS using credit on his account. The database covers the territory of the CR and contains information on about 687 000 documented objects (boreholes, shafts, quarries, caves, wells, surface streams, reservoirs etc.) including 615 000 borehole profiles and 95 000 hydrogeological records. To find the desired objects the user can use a built-in map application or search the database by attributes.

Maximum yield of a groundwater well at peak load referring to the hydraulic conditions at the groundwater body (either maximum drawdown or maximum raise of water level in a well) for a defined well diameter.

Hydraulic conductivity measures how easily a fluid can move through the voids in a material

The elevation above or below sea level at which the surface of groundwater stands

Mean measured groundwater temperature based on surveys.

Extracted water volume per hour and meter drawdown for a defined well diameter.

Maximum yield or pumping rate of a groundwater well doublet per square meter at a given location.

The depth to the top surface of an aquifer from the ground surface.
