Water Conservation and Management Questions

Multiple choice

Which of the following is a positive impact of river meandering?

  1. Creation of diverse habitats for aquatic species

  2. Improved water quality

  3. Flood control

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

River meandering can have several positive impacts, including the creation of diverse habitats for aquatic species, improved water quality, and flood control. Meandering rivers create a variety of habitats, including pools, riffles, and point bars, which support a diverse array of aquatic species. The sinuous course of a meandering river also slows down the flow of water, which allows sediment and pollutants to settle out, improving water quality. Additionally, meandering rivers can help to control flooding by storing floodwaters in their floodplain.

Multiple choice

Which of the following is NOT a characteristic of an abandoned channel?

  1. It is a former river channel

  2. It is no longer actively carrying water
