Each part addresses a specific testing method, and together they provide a complete toolkit for any ground investigation project.

| Step | Activity | |---|---| | 1 | A borehole is drilled to the target depth | | 2 | A temporary slotted liner (e.g. 50 mm uPVC) with a gravel filter pack is installed | | 3 | A short equipment test is performed to establish baseline flow and response conditions | | 4 | Constant head testing is performed with stepwise increases in pumping rate | | 5 | For a falling head test, pumping is stopped and the recovery of water level is recorded | | 6 | Injected water volume and flow rate are measured using flow meters | | 7 | Water level is monitored manually (e.g. with a dip meter) and by automated data loggers | bs en iso 22282-2 pdf

Provides the necessary formulas to calculate permeability from test data. Each part addresses a specific testing method, and

: An instantaneous alteration to the water level is induced (either by adding a slug of water or bailing it out). The rate of head decay or recovery back to equilibrium is systematically recorded against time. It includes both falling-head and rising-head variations. 3. Constant Head Method Best For : General application across stable formations. with a dip meter) and by automated data
