Semi-permeable: This land cover can soak up some water, but not as much as permeable surfaces. Examples: Farmland, soccer fields and lawns. a b "Water Resources Data-Washington Water Year 2005; Snohomish River Basin" (PDF). USGS . Retrieved 5 August 2009. Student are introduced to rivers, and to the components of the water cycle. They think about the effects of communities, sidewalks and roads on the natural flow of rainwater. Students also learn about the role of engineering in community planning and protecting our natural resources.

I’m on the River Severn at this point here on the map… But the river actually starts up in the Cambrian Mountains of mid-Wales here, and runs all the way into the Bristol Channel down here. The second longest river in the UK after the River Severn is the Thames, which stretches right across here and all the way through London. Close your eyes and think about when it rains on the school grounds. What happens to the water if it rains onto a grassy area? Right, the rain water soaks into the ground and plant roots "drink" the water. What happens if it rains onto the sidewalk or parking lot? Correct again! The rain water collects in puddles or runs off of the sidewalk into the grass or the street. Have you ever seen a really large puddle on the sidewalk or road where the rain has nowhere to go? Sometimes these puddles are so big that they make it hard to get to the other side (of the puddle, or the sidewalk!). Open your eyes.

Every river has a starting point called a ‘source’, most are on mountains because that is where rain often falls. Water collects and starts to flow down as a stream. Several of these small streams join together to form a river. At this stage the water is fast flowing and can create rapids, waterfalls, gorges and valleys.

The river begins in the valley formed by Rattlesnake Ridge to the east and Taylor Mountain to the west in the Raging River State Forest, managed by the Washington Department of Natural Resources. It flows northwest, crossing State Route 18, and then continues north past Tiger Mountain, crossing Interstate 90 near Preston, Washington, and joining the Snoqualmie River near Fall City, Washington. The Raging River watershed is part of the larger Puget Sound drainage basin. The average annual flow in the river is 149 cubic feet (4.2m 3) per second [4] and the drainage area is 32 square miles.

I’m in a place called Ironbridge where the River Severn runs through. And later locals Riley and Maisie will be joining me on the riverbank to explore. But first, let’s zoom out.

De-Graft: That is cool. When we talk about rivers, one word that comes up is ‘flooding’. Do either of you two know what it means?
