Pumping Tests
– Short-Term Pumping Tests:
Duration of up to 24 hours, suitable for quickly assessing groundwater conditions and providing initial estimates of hydraulic conductivity.
– Long-Term Pumping Tests:
Duration of several days, continuing until a steady-state condition is achieved. These tests provide detailed information on long-term groundwater conditions and allow for a more precise determination of the hydraulic conductivity (Kf value).
Objectives of Pumping Tests
– Determination of the aquifer’s hydraulic conductivity (Kf value)
– Analysis of drawdown behavior and recovery rates
– Assessment of the permeability and storage properties of the aquifer
Execution of Pumping Tests
– Installation of a pump in the borehole
– Continuous measurement of flow rates, water levels, and drawdown
– Monitoring of fluctuations and stabilization of the water level
Data Evaluation
– Analysis of drawdown and recovery curves to calculate hydraulic parameters
– Preparation of charts and reports to document the results
