Question

Quizplus · Accepted Answer

Planting native trees in the flood fringe actually helps to stabilize stream banks and protects against erosion by slowing down flood waters and promoting infiltration of water into the ground. The other options all involve human activities that can lead to increased erosion in a stream channel. Building a dam can alter flow patterns and sediment transport. Mining gravel removes sediment and alters the stream bed. Building a bridge with roadway fill can alter flow patterns and increase sediment transport. Channelizing the stream upstream can increase the velocity of water, leading to increased erosion downstream.
