What you’ll learn

  1. Storm arrives at a landscapeExplain how wind, pressure, tide, surge, waves, and local geography create uneven storm exposure.Storm arrives at a landscape maps the physical drivers that determine where coastal flooding and wave energy travel.
  2. Wetlands change waves and waterExplain how vegetation, roots, reefs, and shoreline design alter some water and wave pathways.Wetlands change waves and water tests the conditional benefits and limits of living coastal buffers.
  3. Sediment and elevation record impactExplain how deposition, erosion, compaction, and vegetation change the wetland surface after storms.Sediment and elevation record impact follows mixed physical signals through repeated measurement.
  4. Living communities recover unevenlyConnect storm exposure with plant, animal, food-web, and habitat recovery on different timescales.Living communities recover unevenly distinguishes appearance, connectivity, function, and lasting ecological change.
  5. Resilience is managed and measuredEvaluate protection, restoration, baselines, field evidence, remote sensing, and adaptive management.Resilience is managed and measured turns storm response into an evidence-led cycle of decisions and revision.

Questions this course answers

Why can the same storm flood nearby wetlands differently?

Storm forcing interacts with local elevation, pathways, and coastal shape.

Put the storm pathway in order.

Forcing becomes flooding through the landscape before it becomes biological exposure.

What does wetland vegetation mainly add to moving water?

Stems, trunks, roots, and uneven surfaces increase friction, with effects that depend on conditions.

Why are living shorelines not universal storm barriers?

Nature-based protection is conditional and must be matched to a site and hazard.

Why is a storm sediment deposit not automatically a lasting gain?

Elevation depends on deposition, settling, erosion, and biological production through time.

Match each observation with its likely process.

Different field signals point to different parts of the elevation budget.
