Transient Electromagnetic Sounding For Groundwater, David V. Fitterman, Mark T. Stewart Apr 1986

Transient Electromagnetic Sounding For Groundwater, David V. Fitterman, Mark T. Stewart

Geology Faculty Publications

The feasibility of using the transient electromagnetic sounding (TS or TDEM) method for groundwater exploration can be studied by means of numerical models. As examples of its applicability to groundwater exploration, we study four groundwater exploration problems: (1) mapping of alluvial fill and gravel zones over bedrock; (2) mapping of sand and gravel lenses in till; (3) detection of salt or brackish water interfaces in freshwater aquifers; and (4) determination of hydrostratigraphy. These groundwater problems require determination of the depth to bedrock; location of resistive, high-porosity zones associated with fresh water; determination of formation resistivity to assess water quality; and …

Surface Sediment Composition And Distribution In Hillsborough Bay, Florida 1986, City Of Tampa Department Of Sanitary Sewers Bay Study Group

Reports

Surface sediments were mapped to determine the approximate boundaries and percent areal coverage of "mud" in Hillsborough Bay. Depth recorder soundings along 29 transects were used in conjunction with sediment grain size analyses form 19 stations to produce a sediment map.
