Imagine you could fill your school's classroom,
auditorium or other enclosed space with a river of water.
Use flow information from a local river or stream to figure
out how long it would take to fill your space with water.
This activity also helps students visualize a common unit of
flow, the cfs or cubic feet per second.
1) Find the volume of the space to be filled with water. Measure the width, length and height of the space in feet and multiply. This is the number of cubic feet that would fit in the space. 2) Click on the United States Geologic Survey's Water resources page. This link will take you to real-time flow data. You may want to find a source of flowing water near your school Click here to go to the USGS real-time water data. 3) Read the chart or graph on the real-time water data page. This is how many cubic feet of water pass by a gauging station each second. 4) To figure out how long it would take this amount of water, if diverted, to fill your enclosed space, divide the cubic feet of the space you measured by the cubic feet per second of water flow.
