Coastline changes; Hanalei, Kauai

A wall of tangled roots separates the park at Black Pot from the beach, and the erosion has drastically changed the beach from six months ago. While geologists say shifting sands aren’t unusual, it’s a prediction of what could be coming in the next few decades and scientists say long-term studies of the area are necessary.

California cliffs at risk of collapse identified

Danger – Unstable Cliffs – Stay Back: The yellow warning signs that pepper coastal cliffs from northern California to the US-Mexico border may seem overly dramatic to the casual observer. But actively eroding cliffs make up the majority of the California coastline.

Sand in the gears of climate change

For decades it’s been well understood that soft-sand beaches move — and that hard structures like concrete sea walls and stone jetties can in fact accelerate erosion. With climate change — rising sea levels and more frequent violent storms — the inevitable beach erosion and migration has only increased.

Protecting The Netherlands’ Vulnerable Coasts With A ‘Sand Motor’

But the peninsula is more than just a recreation spot. It’s also an experiment in coastal management: It keeps the sea away from nearby cities.
