HRSC Techniques: High-Resolution Hydrogeologic Characterization
The document discusses high-resolution site characterization (HRSC) techniques used in hydrogeologic studies, highlighting various tools such as the membrane interface probe, hydraulic profiling tool, and optical image profiler. It emphasizes the advantages of HRSC, including enhanced site detail, reduced uncertainty, and improved analytical data quality, all of which contribute to more efficient project timelines and better management practices. Additionally, it outlines the applications of HRSC in hydrogeologic modeling, remedial design, and groundwater sustainability.
