The county council says that "...a bridge this long [going across the width of stream] will be too expensive...", so you have been given the job of making the width of the stream smaller. You have learned about streams and know that if you decrease the width, then the velocity will increase under the bridge, possibly destablilizing the bridge abutments.

You live near a stream and your uphill neighbor didn't like the wet area near the stream and brought in fill to raise it up and make it drier. He's thinking that he might sell it to his cousin to build a house on. Because you live downstream from him, you are worried, because you know that "the wet area" was part of the floodplain for the stream. Based on what you know about streams and floodplains, what is likely to happen to the stream near your property now that he filled in his floodplain area? 5.

3. In this next situation, you work for the county and you are planning a bridge for this arid braided stream.
The county council says that "...a bridge this long [going across the width of stream] will be too
