Book Description
This thesis uses Ground Penetrating Radar (GPR) and traditional coring methods to quantify Holocene sedimentation rates in the Trinity River Delta, Texas. Results showed that, while GPR is useful in determining subsurface stratigraphy in coarse-grained environments such as sand bars, it is not useful for subsurface investigations in marshes, where high clay and water content of the sediments attenuate the GPR signal. Radiocarbon dating of shell fragments recovered from sediment cores (292-536cm) ranged from 2.8 to 3.2 Ka. Mean sediment accumulation rates varied between 1.2 and 1.8 mm yr-1 for two areas of the delta, consistent with previous research. At these rates, modern sediment input from the Trinity River is inadequate to account for sediment accretion in the delta. Therefore, other non-fluvial sediment sources must be contributing to the accretion of sediment within the delta.

Collection, Processing, and Interpretation of Ground-penetrating Radar Data to Determine Sediment Thickness at Selected Locations in Deep Creek Lake, Garrett County, Maryland, 2007

Book Description
The U.S. Geological Survey collected geophysical data in Deep Creek Lake in Garrett County, Maryland, between September 17 through October 4, 2007 to assist the Maryland Department of Natural Resources to better manage resources of the Lake. The objectives of the geophysical surveys were to provide estimates of sediment thickness in shallow areas around the Lake and to test the usefulness of three geophysi-cal methods in this setting. Ground-penetrating radar (GPR), continuous seismic-reflection profiling (CSP), and continuous resistivity profiling (CRP) were attempted. Nearly 90 miles of GPR radar data and over 70 miles of CSP data were collected throughout the study area. During field deployment and test-ing, CRP was determined not to be practical and was not used on a large scale. Sediment accumulation generally could be observed in the radar profiles in the shallow coves. In some seismic profiles, a thin layer of sediment could be observed at the water bottom. The radar profiles appeared to be better than the seismic profiles for the determination of sediment thick-ness. Although only selected data profiles were processed, all data were archived for future interpretation.
