FHWA Subsurface Investigations: Groundwater
Credits: 2 PDH
PDH Course Description:
Groundwater conditions and the potential for groundwater seepage are fundamental factors in virtually all geotechnical analysis and design studies. Accordingly, the evaluation of groundwater conditions is a basic element of almost all geotechnical investigation programs. Groundwater investigations are of two types: determination of groundwater levels/pressures and measurement of the permeability of the subsurface materials.Topics:
- Determination of Groundwater Levels and Pressures
- Open Borings / Observation Wells
- Water Level Measurements using Chalked Tape and Tape w/ Float
- Electric Water Level Indicators
- Data Loggers for Water Level Measurements
- Field Measurement of Permeability
- Seepage Tests
- Constant, Falling, and Rising Water Level Methods
- Pressure (Packer) Tests
- Pumping Tests
- Slug Tests
- Piezocone Dissipation Tests
