The computation of pumping in groundwater storages still based on the general pumping formulas, although they have different condition of flows on the tip of casing. The groundwater drawdown due to pumping depends on well conditions, casing and geometric intake of the well. Based on these conditions, the aquifer test analysis has to use appropriated equations by using the intake shape factors. In 1930, Forchheimer was developed the first shape factors based on well conditions. In the subsequent years, researchers developed the shape factors equations with various well conditions. Some of the assumptions of shape factors are based on theoretical assumptions and have not been proved in the fields. These shape factors need to be proved and modify to get more reliable formulas by doing the experimental tests. The main goal of this research is to proof some of the existing shape factors related with appropiate well and aquifer conditions. The experiments under constant discharge will be carried out to get the correct formula of the shape factors. The benefit of these experimental tests is much simpler approach to the computation of groundwater in general.
