Developers don’t get it: climate change means we need to retreat from the coast, Guardian UK (15-03-2016)
It is preposterous to build in areas that are bound to flood. So why are real estate companies still doing it?..

Coastal Hazards & Targeted Acquisitions: A Reasonable Shoreline Management Alternative: North Topsail Beach, North Carolina Case Study; by the Western Carolina University Program for the Study of Developed Shorelines (July 1, 2019)
This study is the first of several case studies to be released by the Program for the Study of Developed Shorelines examining the feasibility and economics of targeted acquisition strategies in oceanfront, resort communities. Buyouts of vulnerable properties have become an increasingly popular tool for reducing future exposure in flood-prone communities across the U.S.

The only answer to rising seas is to retreat; By Orrin H. Pilkey & Keith C. Pilkey; The News & Observer (10-18-2017)
Except for the timing, there is no controversy among scientists regarding sea level rise. Defending the coast and holding the shoreline in place ultimately will be futile. With a three-foot or a six-foot sea level rise, we will retreat, probably beginning within the next 50 years…

Excerpts;

Research on the Big Island’s coastal erosion, led by a University of Hawaii at Hilo graduate student, is being used to shape county planning policies.

Hawaii County is the only county in the state that hasn’t done research to understand the island’s shoreline changes.

Despite the island’s differing shoreline geology, the county’s initial general plan only required a development setback distance of 40 feet from shorelines across the entire island…

Doubling of Coastal Erosion by Mid-Century in Hawai’i, Science Daily (03-24-2015)
Chronic erosion dominates the sandy beaches of Hawai’i, causing beach loss as it damages homes, infrastructure, and critical habitat. Researchers have long understood that global sea level rise will affect the rate of coastal erosion. However, new research indicates that coastal erosion of Hawai’i’s beaches may double by mid-century…

A $700,000 — 95-foot-long sand bag groin made of 83, 10,000-pound bags of sand — installed in November to restore the coastline and slow erosion at Kuhio Beach, is to be followed by another more expensive project.

The more than $2 million project — proposed by the DLNR — that will launch next month, will involve replacing the Royal Hawaiian groin with a stable, sloping rock groin, as well as pumping dredged sand in…

Terminal Groins Don’t Stop Erosion; Coastal Review (05-03-2016)

The Negative Impacts Of Groins, (02-12-2009)
The negative impact of groins on downdrift shorelines is well understood. When a groin works as intended, sand moving along the beach in the so-called downdrift direction is trapped on the updrift side of the groin, causing a sand deficit and increasing erosion rates on the downdrift side. This well-documented and unquestioned impact is widely cited in the engineering and geologic literature.

Seawalls: Ecological effects of coastal armoring in soft sediment environments; Science Daily (07-24-2017)
For nearly a century, America’s coasts — particularly those with large urban populations — have been armored with human made structures such as seawalls. These structures essentially draw a line in the sand that constrains the ability of the shoreline to respond to changes in sea level and other dynamic coastal processes…

In response to the detrimental environmental impacts caused by traditional erosion control structures, environmental groups, state and federal resource management agencies, now advocate an approach known as “Living Shorelines”that embraces the use of natural habitat elements such as indigenous vegetation, to stabilize and protect eroding shorelines.

Can these giant dams keep Europe from drowning?

Excerpts;

A plan for a giant a 400-mile enclosure, The Northern European Enclosure Dam (NEED), would cut off the North and Baltic Seas from the Atlantic Ocean to protect 15 European countries from those rising seas.

The project’s scale is unprecedented. Its cost phenomenal. But it’s still cheaper than all the alternatives—including doing nothing. All the alternatives except one: Taking action now against climate change…
