Geotechnical Investigation and Testing - Geohydraulic Testing - Part 4: Pumping Tests
Also Known As:
DIN EN ISO 22282-4 is a standard that focuses on geohydraulic testing, specifically pumping tests, which are conducted as part of geotechnical investigation services. This standard is in accordance with EN 1997-1 and EN 1997-2, which provide guidelines for geotechnical design and testing.
The standard specifically deals with pumping tests performed on aquifers with permeability levels that allow for a rapid decrease in piezometric head (water level) within hours or days. The tests can be conducted in both soil and rock formations. The main purpose of these tests is to evaluate the hydrodynamic parameters of the aquifer, as well as the well parameters, including aquifer permeability, radius of influence, pumping rate, drawdown response in the aquifer during pumping, skin effect, well storage, and recovery response in the aquifer after pumping.
