In this class activity, students determine the discharge of a 100-year flood for two human-impacted streams. This activity supports the quantitative concepts of recurrence intervals, floods and flooding, and probability. It is appropriate for a class of under 40 students. This assignment uses real data, asks students to graph and interpret data, examines the errors associated with that data and its analysis, and requires the students to look at societal impacts. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
