Which effect causes increased coastal erosion when longshore transport is disrupted?

💡 Explanation

Increased coastal erosion occurs due to wave refraction amplification when structures obstruct longshore transport, because sediment starvation causes incident waves to focus energy onshore, therefore increasing erosion rates rather than distributing sediment more evenly.

• Which erosional outcome dominates when persistent winds encounter unconsolidated alluvial plains?
• Which primary outcome arises when Ekman transport concentrates floating plastics toward the center of an oceanic gyre system?
• Which long-term effect arises from carbonic acid presence?
• Which outcome increases as groundwater acidity rises during limestone dissolution, creating sinkholes?
• Which mechanism substantially deflects ocean currents flowing from the equator towards higher latitudes?
• Which risk rises when groundwater flow increases where fractured limestone underlies epikarst?
