Combining Aquifer Tests with Heat Tracer Experiment to Estimate Site-Scale Aquifer Properties

Project Details

Description

The understanding of hydrogeological conditions and aquifer parameters (i.e. transmissivity and storage coefficient) at sites play an important role in groundwater resource management, engineering design, and aquifer remediation. This study aims to conduct assessment of aquifer heterogeneity using multiple hydraulic tests at the same well field, comparing the estimations by different data analysis methods, and then carrying out the insight into the use of hydraulic surveys at the field-scale site. Single well, multi-well, and cross-hole constant rate pumping tests are conducted at the well field. The well field has 19 installed wells, including five 4-inch wells that are considered to be the pumping wells. On the other hand, the heat carried by groundwater serves as a tracer to estimate the direction and velocity of groundwater flow in the site. By using heater to increasing temperature at different well to generated anomaly signal. These temperature anomalies are used to estimate thermal and hydraulic conductivity by inversion numerical model. The result of hydraulic tests will be use to compare with the result of heat tracer test. The results of this study could provide a more efficiently approach to obtain the spatial distribution of aquifer parameters. This could help the project management to have more information to come out a better decision under same budget.
