🌊 How do coastal wetlands recover from storms?

Follow surge, waves, erosion, sediment, surviving roots, and restoration to see why one storm can damage a wetland and also reshape its path to recovery.

What you’ll learn

  1. A storm changes the water's speed and heightExplain how surge, waves, vegetation, and coastal geometry combine to shape storm impacts.Storm damage depends on the storm's water level and energy as they meet a particular wetland landscape.
  2. Damage is a process, not just a photographDistinguish erosion, plant stress, sediment deposition, and belowground recovery after a storm.Visible damage becomes understandable when repeated measurements connect shoreline change with soil, sediment, and plant processes.
  3. Resilience depends on what happens between stormsEvaluate process-based restoration, habitat networks, and monitoring as parts of wetland storm resilience.Recovery is more durable when connected habitats and interventions repair the process that limits a wetland, then test the result.

Questions this course answers

What makes storm surge different from an ordinary high tide?

Storm surge is an abnormal rise in coastal water driven mainly by storm winds and air pressure, added to the tide already occurring.

Why can storm sediment sometimes help a marsh later?

Storm deposits can contribute to elevation, but their effect depends on thickness, location, grain size, and plant survival.

Put a process-based storm-recovery study in order.

A credible recovery study establishes a starting point, diagnoses the mechanism, tests a matched response, and follows the result over time.
