Stream discharge is a fundamental measure of water supply in stream systems. Low discharge may cause problems with water supply and fish passage, while high discharge may mean flooding. In this module, students explore real-time stream discharge data available from the United States Geologic Survey. Students use this data to assess changes in discharge with time, calculate flood frequency, and see the effects of urbanization and flood control. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

This module can be completed in a single 3-hour lab period with upper-level undergraduate students, especially if the last part of activity C is given as a homework assignment. It is not necessary to do all of the activities. You may wish to skip Activity A for advanced students or Activity C.2 for beginning students. Students will need 1-2 hours outside of class to read the assigned readings, and will need 1-2 additional hours after the exercise if C.2 is assigned as homework.
This module has been used in courses in introductory geology, environmental geology, and surface water hydrology. However, we believe the module could be successful in many courses. Instructors should look over the material to decide how to best tailor these activities to their courses.
