Presented by Keith Halford, Halford Hydrology LLC
Groundwater flow rates and storage volumes cannot be measured directly and are estimated indirectly from aquifer-test results, which are controlled field experiments. Transmissivity and storage coefficient are principal results that define behavior of groundwater systems in response to pumping. Volume of water displaced or rate of water pumped are the principal controls that allow estimation of transmissivity and storage coefficient by fitting analytical or numerical solutions to observed water-level changes.
A 1-day, aquifer-test class will cover fundamental concepts of aquifer-system responses to pumping and slugging wells. Material will emphasize practical aspects of analyzing and interpreting slug test and single-well pumping aquifer tests. Field conditions and limitations will be considered for measuring waterlevel and discharge data. Expected ranges of aquifer properties and empirical correlations between specific capacity and transmissivity will be presented. Design, interpretation, and limitations of multiple-well aquifer tests will be presented. Aquifer-test results will be compared robustly to simulated hydraulic properties in groundwater-flow models. Guidance for reporting aquifer test results will be provided. Presentations and material will be similar to those presented previously, NWRA Aquifer-testing class, March 25, 2025.
Data will be reduced, single-well tests will be interpreted, and simple problems will be analyzed during class exercises.
