Which consequence arises when a coastal engineering project disrupts longshore drift?

💡 Explanation

Disrupting the natural longshore drift sediment transport causes down-drift starvation, because sediment deposition ceases downstream; therefore, increased erosion dominates, rather than the continued equilibrium that natural drift sustains through sediment replenishment.

• Which consequence results when rapid tectonic uplift occurs?
• Which outcome occurs when widespread destabilization of permafrost increases?
• Which outcome primarily occurs from long-term sediment displacement into a glacial lake?
• Which atmospheric effect results when the descending air from a Hadley cell warms adiabatically near 30 degrees latitude?
• Which coastal effect reduces dune formation when seawalls are erected on a sandy beach complex?
• Which increased occurrence accompanies divergence in upper-level air streams?
