Rollin' on the River
I took the Dunn Middle School 8th grade to the Santa Ynez River last week with the assignment to measure the flow in gallons per second. With three dams upstream and our usual 6 month summer drought, the river is not large, only about 30 feet across and a foot deep. That's a far cry from last year's floods! Part of the assignment was to devise a method for the task. But first, the kids had to decide where to measure the flow. One section of the river was deep and barely moving. Another place was narrow and swift. Would that make a difference?
