Book Description
A technique for measuring the direction of movement of sandy sediments by means of a radiotracer is described. An artificial sediment fabricated from glass containing a small percentage of arsenic is irradiated in a nuclear reactor to produce 76 As (T 1/2 = 26.4 hr). This material is then inserted into the particular sediment to be studied and its movement followed by monitoring the 560-keV gamma-ray emission with a submersible NaI detector. A test of the method at Point Pelee on the north shore of Lake Erie with 140 g of artificial sediment containing 180 mCi of 76 As demonstrated that the redistribution of the radioactive material by the bottom current could be readily followed for at least three days after insertion.

Book Description
Sediment transport and soil liquefaction under wave loading are major concerns for offshore hydrocarbon developments in Canadian waters. This report presents a state-of-the-art review of five topics concerned with seabed mobility and liquefaction, together with a summary of research priorities to address a number of outstanding problems facing the offshore industry. The review deals with sediment transport produced by waves and currents without structures such as pipelines or platform footings present to modify the flow. Thus such topics as localized scour around structures are not considered.
