Test pumping is an essential part of groundwater studies and is most often required when quantitative data on water resources are needed.
Test pumping is a hydraulic test of the aquifer. It is the operation by which the hydrogeologist determines the operating rate of a structure (borehole) and estimates the parameters of the groundwater flow laws. In particular, the interpretation of a test pumping allows the quantification of parameters specific to the structure and hydrodynamic parameters characteristic of the aquifer.
OUAIP, developed by the BRGM, is a freeware application designed to interpret and simulate hydrogeological pumping tests. It offers a range of analytical solutions (e.g. for porous, fissured, captive or semi-captive environments) and also handles disruptive effects (related to wells, limits, capacity, etc.).
