Oregon's Ever-Changing Coastline. Another Title in the Series "Learning About the Ocean."
Katz, Barbara A.; Gabriel, Stephen R.
This bulletin contains a non-technical introduction to the forces that change the coastline and how engineers can sometimes modify their effects with occasionally unpredicted consequences. This publication introduces the reader to the basic geology of the Oregon coast. Next, an explanation of wave action discussing the changes in a beach due to wind and storm caused wave action is presented. Long shore currents, and littoral drift, erosion and accretion are other forces that are explained. Shoreline modifications such as rip-rap, seawalls, dikes, breakwaters, and jetties are discussed. Pictures or diagrams of actual structures are provided as examples. Cases of the use of these structures and their effects are also included in the discussion. In several places references are made to the suggested reading list that is included. Also, a table of metric/English conversion factors is provided since most distances in the bulletin are given in metric units. (MR)
