Course Description

This course enables the participant to make technically sound and efficient discharge-frequency estimates. The course focuses on the theoretical basis for frequency analysis, application of techniques contained in the "Guidelines for Determining Flood Flow Frequency," Bulletin 17C, and application of the computer program HEC-SSP. The course is intended for engineers, hydrologists, and others involved in developing discharge-frequency estimates at gaged and ungaged locations.
