What you’ll learn

Storms arrive as several forcesExplain how wind, waves, surge, rainfall, tides, and timing combine to expose coastal wetlands.Storms deliver multiple forces whose effects depend on local elevation, shape, and timing.
Storms reshape wetland formTrace erosion, deposition, channels, barriers, and roots as storms redistribute wetland sediment and water.Storms can remove, deposit, and redirect material, changing the wetland's future drainage and stability.
Life continues after disturbanceCompare vegetation, wildlife, debris, salinity, and recovery time after storm disturbance.Living systems recover at different speeds, and visible greening does not prove that every function has returned.
Recovery can cross a thresholdEvaluate elevation, living shorelines, restoration pathways, and landscape-scale limits on storm protection.Recovery depends on elevation, sediment, connectivity, space, and interventions that fit local processes.
Evidence guides the next decisionDesign before-and-after, satellite, field, and adaptive monitoring for coastal-wetland storm response.Resilience claims become useful when they identify a function, a place, a time scale, and evidence that can revise the plan.

Questions this course answers

Why can the same storm affect two wetlands differently?

Storm response depends on several interacting forces and local conditions.

What is storm surge?

Surge is a storm-driven water-level rise that can combine with the astronomical tide.

Put a storm-erosion assessment in order.

A baseline, post-storm survey, comparison, and follow-up establish change and persistence.

Why can sediment be both helpful and harmful?

The effect depends on deposit thickness, grain size, chemistry, and the organisms underneath.

What does a quick return of green color prove?

Appearance can improve before belowground structure and ecological functions recover.

Why should debris cleanup be planned carefully?

Cleanup can solve one problem while creating another if machinery damages the wetland.
