This document establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997\u20111 and EN 1997\u20112.<\/p>\n
This document applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock.<\/p>\n
The tests concerned by this document are those intended for evaluating the hydrodynamic parameters of an aquifer and well parameters, such as:<\/p>\n
permeability of the aquifer,<\/p>\n<\/li>\n
radius of influence of pumping,<\/p>\n<\/li>\n
pumping rate of a well,<\/p>\n<\/li>\n
response of drawdown in an aquifer during pumping,<\/p>\n<\/li>\n
skin effect,<\/p>\n<\/li>\n
well storage,<\/p>\n<\/li>\n
response of recovery in an aquifer after pumping.<\/p>\n<\/li>\n<\/ul>\n
