|Abstract: Water Haves and currents vary among other things, with geography, water level (stage of tide), season, and offshore slope. The net effect of wave and current forces impinging upon a shoreline; ocean or lake is to change the morphology of the coastline as a result of erosion, transport, and deposition of sediment. In general, the model of sediment transport can be thought of as movement of a sand grain from some source such as a headland, to a barrier beach, to a dune, into an inlet or to an offshore sink. Knowledge of the processes of erosion, transportation, and deposition of sediment implicit in this model is of value to the engineer and the geologist as well as the shoreline property owner. Concepts of generation of water motions and directions of flow, characteristics of the flow, water levels and their periodicity, bed form generation and movement, and sediment entrainment and transport are fundamental to the understanding of lakeshore processes. Basic aspects of these concepts, in lay terms, are presented in this report.
