Which outcome increases near groynes, because of longshore transport disruption?

💡 Explanation

Increased sediment deposition updrift occurs because the groyne obstructs longshore drift, promoting deposition on the updrift side. Consequently sediment starvation increases erosion downdrift, rather than a general reduction of erosion.

• Which mechanism leads to transverse dune formation when limited sediment is transported?
• Which consequence results when a jetty interrupts longshore transport pathways?
• Which risk increases when ephemeral desert streams overflow?
• Which risk increases following a large subduction-zone earthquake in coastal regions?
• Which risk sharply increases when hydraulic head rapidly decreases within karst aquifers supporting residential development?
• Which outcome occurs when disruption amplifies within Hadley cells?
