Which outcome increases following widespread dam construction, inhibiting sediment drift?

💡 Explanation

Increased coastal erosion happens because sediment supply diminishes, hindering deposition; this is shoreline retreat due to sediment starvation, rather than wetland expansion, which requires sediment accretion; increased storm surge, therefore increased erosion.

• Which outcome results from channel avulsion in braided streams?
• Which outcome occurs when nearshore wave refraction diminishes along a coastline exhibiting longshore drift?
• Which risk increases when rapidly rising floodwater overtops a natural levee along a major river?
• Which seafloor feature results where subduction arrests due buoyancy?
• Which process most directly inhibits crust formation around rhyolitic lava domes?
• Which mechanism causes increased stream meandering in regions where the jet stream weakens and becomes more zonal?
