Aspects of Great Lakes Seiche Affected Estuary Transport. Volume 2. Littoral Drift Processes at Estuary Mouths - A Case Study at Old Woman Creek in Lake Erie

摘要

The report is one of a four volume report series which details aspects of estuary-like behavior in river mouths adjacent to Lake Erie. The second volume explores alterations in sediment transport occurring in a typical river mouth zone. The study presents an initial effort to determine the physical processes that occur at the Old Woman Creek (OWC) mouth. Littoral transport rates, seiche activity, streamflow and sediment characteristics are the most important process parameters. A bilateral approach is used to examine the littoral transport rates at OWC. The first method used is measurement of the drift accumulation over time at the jetty near OWC and to use the measurement as an estimate of the net littoral transport volume. The second method uses wind data for the same time period to hindcast waves which in turn empirically predict transport volumes. The results of the two methods are compared for similarities.
