SummaryStudents build on their understanding and feel for flow rates, as gained from the associated Faucet Flow Rate activity, to estimate the flow rate of a local river. The objective is to be able to relate laboratory experiment results to the environment. They use the U.S. Geological Survey website (https://waterdata.usgs.gov/nwis/rt) to determine the actual flow rate data for their river, and compare their estimates to the actual flow rate. For this activity to be successful, choose a nearby river and take a field trip or show a video so students gain a visual feel for the flow of the nearby river.
Civil engineers design the systems that bring water from natural resources, such as rivers or lakes, to the communities where that water is needed. Civil engineers also oversee natural systems, such as river basins and watersheds, for flood control and drought mitigation. Completing this activity gives students a greater understanding for what civil engineers who design water systems do, as well as the skills they use.
After this activity, students should be able to:
- Use experimental data to formulate hypotheses.
- Use the Internet to find the flow rate of a specific river.
- Analyze discrepancies between estimated and actual data.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.

Understanding flow rate and determining the flow rate of rivers is important in engineering analysis and design so that our infrastructure provides sufficient amounts of water when and where it is needed. Now that you have first-hand experience with flow rates from water faucets, let's extend your flow rate knowledge to rivers and streams.
Before beginning the activity with students, use the data on the USGS website to locate the flow rates for rivers in your geographical area.
- Hand out the River Flow Rate handouts.
- Introduce and explain the activity to students.
- Have students assemble into their groups, and write down their hypotheses (best estimates) about the flow rate of a local river. For greatest benefit, choose a nearby river that students are familiar with, or take a field trip.
- Have each student group assemble at a computer with Internet access. If computers are limited, do this portion of the activity as a class. Bring up the Daily Streamflow Conditions page at the USGS Current Water Data for the Nation website at https://waterdata.usgs.gov/nwis/rt.
- If students have never used the USGS website, walk through the process to find the flow rate for an example river.
- Have student teams complete the worksheets.
- As a class, compare estimates and real-world flow rate data.
At activity end, compare estimates and real-world data. Collect and review worksheet answers to gauge students' comprehension of the subject matter.
