FE Civil Exam Prep 53, Unit Hydrograph and Storm Hydrograph

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - A unit hydrograph represents the direct runoff from exactly one inch (or cm) of effective rainfall over a specific duration. - To calculate a storm hydrograph, you multiply the unit hydrograph's flow rates by the actual depth of effective rainfall. - The most frequent exam trap is using total rainfall instead of effective rainfall; always subtract infiltration and other losses first. - The principle of linear superposition requires that the storm's rainfall duration matches the specified duration of the unit hydrograph. - Total streamflow is the sum of direct runoff (from the storm hydrograph) and the baseflow present in the channel.
