What is a wetland and why is it important?

Why are wetlands important? Wetlands associated with streams and rivers slow down floodwaters by acting as giant shallow pans. Water flowing into these pans loses speed and spreads out. Plants in the wetland play an important role in holding back the water.

What is a wetland test? WETLAND WATER TESTING. Summary. Using card games, hands-on activities, computer activities, and water quality vocabulary, students understand some different properties that affect water quality, and learn to measure one chemical characteristic that helps determine water quality. Objectives. Objectives.
