 Provides land/space on which to live  Provides necessary resources required for survival, like food and fuel.

The Coast temporary junctions between land and sea are subject to change –waves, currents, tides, biological processes, tectonic activity position changes.

Coasts. Wave erosion coasts formed by the force of waves as they strike the land the waves strike the land and pieces of rock are broken off the wave.

Sand Migration and the Impact of Infrastructures

Types of infrastructures

Types of infrastructures

“newjerseyization” seawalls, groins, and jetties impacted the coast

Impacts of jetties

Impact of seawalls

Impacts of groins

Dangerous waters for swimmers produced by groins

Scuba steve and marine life affected by dredging for beach renourishment

Dangerous currents, but good waves

Impacts of infrastructures Stabilize beach Build-up sand Create dredging problems Create rip tides and dangerous currents Cause more $ to be spent on renourishment Leads to indirect problems ( sand harvesting=destruction of marine habitats, etc.) Cause us to believe coastal areas are safe for development (only temporary)
