Improving groundwater flow model parametrization techniques
… and compares it with the results of conventional pumping test analysis and analysis of a water level response to atmospheric pressure fluctuations and Earth tides. The resulting values of specific storage have shown reasonable agreement between methods for a sandstone unit of the Paskapoo …

Evaluation of Fracture Flow at the Coles Hill Uranium Deposit in Pittsylvania County, VA using Electrical Resistivity, Bore Hole Logging, Pumping Tests, and Age Dating Methods
… resistivity profiling, bore hole logging, a pumping test, and age dating and water chemistry. In this thesis groundwater flow is confirmed to occur from the Piedmont crystalline rocks across the Chatham Fault and into the Triassic basin at the study area as evidenced by pumping test data and …

Discrete-Fracture Dual-Permeability Simulation of Heterogenous Drawdown in the Brunswick Group, North Penn 6 Superfund site, Landsdale, Pennsylvania
Aquifer pumping tests conducted by the U.S. Geological Survey (USGS) at the John Evans Site (North Penn 6 Superfund Site, Lansdale, PA) produced anomalous water level changes in observations wells. In some observations wells, changes were not radially symmetric, and more distant wells had greater …

Hydrogeological characterisation and water supply potential of Lebalelo South, Limpopo Province of South Africa
… as high permeability zones in fault planes. Step test, constant discharge test and recovery tests were conducted on all the boreholes to stress the borehole. This was used to determine a suitable and sustainable pumping rate of the aquifer. Pumping test data from the pumping period and recovery …

Characterization of a hydraulically induced bedrock fracture
… approach consisting of aquifer and tracer testing is used to estimate the transmissivity and storage coefficient of a hydraulically induced fracture and observe its behavior as a contaminant flow pathway. The results of the aquifer tests indicated a decrease in both the transmissivity and …

Risk assessment and uncertainty analysis in groundwater modelling
… based on the measured data in the field (i.e. pumping test results) and the historical data. However, the most difficult parameter to estimate was the groundwater recharge. This parameter was estimated using two different models for groundwater recharge estimation and the results were compared …
