Testing of Bulletin 17C Hydrology Procedures

The Subcommittee on Hydrology of the Advisory Committee on Water Information is proposing an update to Bulletin 17B, Guidelines for Determining Flood Flow Frequency, which was published in March 1982.

WWE’s Julia Traylor, Brik Zivkovich and Shannon Tillack were pleased to test the new Bulletin 17C procedures on actual stream gauge station records for evaluating the ease of use of the software and the clarity of the procedures.

Four gauge records with varying scenarios were tested using both the U.S. Geological Survey (USGS) PeakFQ and U.S. Army Corps of Engineers (USACE) HEC-SSP software. WWE would like to thank Will Thomas Jr., P.E., of Michael Baker International for the opportunity to conduct testing.
