    As discussed in Chapter 1, coastal erosion is often defined in terms of the movement of shore contours, and can be caused either by sea-level rise or by removal of geologic materials that make up the shoreline. Because rising sea level exposes portions of the shoreline to actions of waves and current, sea-level rise can exacerbate erosion.

ABOUT SHOREZONE ShoreZone takes a close-up inventory of the biology and geology of North America’s Pacific coast from Oregon to Alaska and in-between. People use the coastal data, imagery, and maps to manage the coast for the benefit of the many. Further, although Goal 17 states a preference for alternatives to shoreline structures riprap remains the preferred actual response to dune and bluff erosion.

Public Education Program. Oregon utilizes books, signs, maps, and websites to educate the public about coastal erosion, beach fill, shoreline structures, and related issues. Coastal erosion is a natural process that continually affects the Oregon coast.

Erosion becomes a hazard when human development or public safety is threatened. Beaches, sand spits, dunes, and bluffs are constantly affected by waves, currents, tides, and storms, resulting in chronic erosion, landslides, and flooding.

analyze and integrate current public policy regarding coastal erosion and shoreline armoring with the latest relevant geospatial and natural science information (including predicted impacts of climate change), in order to understand the most vulnerable coastal areas.

The Oregon coast is currently about 5% armored ( miles). The objective of this book is to focus on the physical processes that cause coastal scientists and engineers have focused their research on the entire range of physical processes from the waves and the currents in the nearshore to the response of the beach, via sand transport, resulting in a changing coastal morphology.

Many beaches along the Pacific Northwest coast have experienced increased erosion since the late s. So says the U.S. Geological Survey, which is working with Oregon. Coastal Engineering Inventory. A reconnaissance-level investigation, analysis and inventory of coastal engineering projects in ten coastal national parks was completed by the Program for the Study of Developed Shorelines at Western Carolina University with funding provided by the National Park Service Recreation Fee Program.

Oregon has a long and tortured history with people pushing the bounds of shoreline safety. Perhaps the most famous example is the demise of Bayocean, sometimes referred to "the town that fell into. nature. A living shoreline is an example of a nature-based feature.

• Structural measures: Structural measures include sea walls, groins and breakwaters. These features reduce coastal risks by decreasing shoreline erosion, wave damage, and flooding.

• Non-structural measures: Includes modifications in. its junction with Oregon State (FAS ) to its junction with the Oregon Coast Highway, near Bandon; and 2.

All lands within an area defined by a line measured horizontally (a) feet from the shoreline of estuaries; and (b) feet from the shoreline of coastal lakes. COMPREHENSIVE PLAN REQUIREMENTS Based upon inventories.

Erosion can threaten buildings and roads resulting in a desire to "harden" the shoreline against wave attack. At the same time, Oregonians have always considered the ocean beach to be a public resource and legacy, and shoreline armoring, while sometimes able to protect private property, can have negative effects on the public beach.

the segment of shoreline is expanding. Along the Oregon coast, potential sources of sand include rivers, bluffs, dunes, and the inner shelf. Potential sinks include, bays, dunes, offshore dredging, and mining.

Attention is often focused on the effects of beach and dune erosion. Yet, there are seg-ments of Oregon’s coast where the principal. Introduction. Erosion response is a measure of how well a state's policies and procedures limit the extent of shoreline armoring, unsafe coastal development, and costly beach nourishment projects, and conduct preemptive planning for sea level rise.

Then, according to historical information on the shoreline transformation and on the direction of wave propagation, the model predicts the changes of each line segment so to derive the next shoreline. A map of the beach profile evolution is depicted to compare the time trend and the level of coastal erosion risk.

Sea level rose during the 20th century, and observations and projections suggest that it will rise at a higher rate during the 21st century. Rising seas increase the risk of coastal flooding, storm surge inundation, coastal erosion and shoreline retreat, and wetland loss.

Executive Summary. Beach erosion is a chronic problem along most open ocean shores of the United States. As coastal populations continue to increase and infrastructure is threatened by erosion, there is increased demand for accurate information regarding past and present trends and rates of shoreline.

Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms.

The landward retreat of the shoreline can measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Purpose and Potential Applications: This data set was featured as base maps to construct nautical charts primarily used for t applications include shoreline change analysis and cartographic representation.

Maps identified high-risk exposures in association with infrastructure and areas of low biomass or bare ground in proximity to coastal erosion zones. Outputs were used to create a land cover classification and map coastal risk hazards on the Upper Peninsula’s Lake Superior shoreline, Michigan’s east shoreline of Lake Michigan, and a mile.

Headlands divide the coast of Oregon into sections called littoral cells, or "sandsheds." These natural divisions allow Oregon's coastal managers to take a regional approach to coastal hazards planning. David's project involved a three-step process in the development of a management plan: inventory, risk assessment, and implementation.
