Question

Which scenario is LEAST likely to cause sedimentation?A - fast-moving river slowing down at bends in the riverB- a river increasing speed as it moves down a steep watershedC- storm surge from the coastline traveling inland at sea levelD- flood waters moving over their riverbanks during storms

Answer 1

The scenario least likely to cause sedimentation is the one which wouldn´t allow sediments that are being transported by the water to accumulate. In this examples, the answer is a river increasing speed as it moves down a steep watershed. As the speed increases, the sediments are going to travel faster down the river so they won't accumulate.
