WebMar 29, 2024 · The step test involved four pumping rates, each of which reached steady-state drawdown. The measured and calculated data are given in Table 4 and Fig. 3. Even at the rather low initial pumping rate of Q = 30 m 3 /h, the well already shows nonlinear losses, which become quite severe at higher pumping rates. This is probably due to a … WebOct 26, 2024 · Suggested Operating Procedures for Aquifer Pumping Tests.

WebA constant-rate pumping test executed during 171 h in the Guarani Aquifer System (GAS) was used to determine its respective hydraulic parameters and to test the existence of a drainage through an 84-m basalt layer (Serra Geral Aquitard), and the underlying sediments of the Corumbataí Formation. The test was prformed in a pumping well with hydraulic … WebFollowing a step test, water levels must recover fully before the constant rate test starts. It is recommended that, where step drawdown tests are undertaken, the advice given in BS ISO 14686:2003 is followed. 2.3 Constant Rate Pumping Test This should consist of a test at the proposed maximum abstraction rate and be at a constant discharge rate.
