Radioactive sediment tracer tests Houston ship channel, Houston, Texas

Abstract

Radioactive sediment tracer tests were conducted to determine qualitatively sediment movement in channel; about 5 C of isotope, Au-198 was thoroughly mixed with sediment samples from channel, and activated sediment was then deposited along bottom at two locations; results of tracing deposits indicated that activated sediment moved upstream for several miles; activity was recorded downstream for only short distance; very little lateral movement out of channel was detected
