Pumping test 105 experimental

A pumping test consists in principle of: drawing down the piezometric surface of the groundwater by pumping from a well (the test well),measuring the pumped discharge and the water level in the test well and piezometers, before, during and after pumping, as a function of time. The following hydrodynamic parameters of an aquifer and well parameters, are evaluated : permeability of the aquifer,radius of influence of pumping,pumping rate of a well,response of drawdown in an aquifer during pumping,skin effect,well storage,response of recovery in an aquifer after pumping.

fr Un essai de pompage consiste à : abaisser le niveau de la surface piézométrique par pompage depuis un puits (le puits d'essai), mesurer le rabattement et le niveau d'eau dans le puits d'essai et les piézomètres d'observation, avant pendant et après le pompage, en fonction du temps. Les paramètres hydrodynamiques suivants, de l'aquifère et du puits peuvent être évalués : la perméabilité de l'aquifère, le rayon d'influence du pompage, le débit de pompage du puits, le rabattement dans l'aquifère, l'effet de peau, la capacité d'emmagasinement, le rétablissement de la nappe après l'arrêt du pompage.
