HEC-HMS with Application to Dam Safety participants will gain a practical knowledge of methods for simulation of runoff from storm rainfall. The methods covered relate to the processing of historical and hypothetical (design-storm) rainfall data; estimation of losses (infiltration); transformation of rainfall excess to direct runoff with unit hydrographs; routing of flood waves; calibration of model parameters; and modeling of runoff from watersheds. Experience will be gained in applying the methods with the program Hydrologic Modeling System (HEC-HMS). Where possible, applications will emphasize hydrologic computations for dam safety.

Key takeaways attendees will receive from this course:

  • Methods to simulate runoff from storm rainfall.
  • Estimating hydrologic abstractions and transforming excess rainfall using unit hydrograph theory.
  • Evaluating dam and reservoir performance during flood events.
  • Running the HMS model on several real-world problems.
  • Estimating uncertainty in modeling runoff.

Up to 20 PDHs are available for the completion of the course. NY licensed engineers please check back close to the course for details on the number of PDHs available.

For those with no background in Hydrology, it is highly recommended that you review the ASDSO Hydrology 101 for Dam Safety Webinar. This webinar will offer fundamentals of hydrology and is an introduction to the Hydrologic Processes. This is not required but should offer a good basis for the topic.

ASDSO members can register for only $900 and non-members can register for $1,000 (non-members can become a member before registering and save!).

Amanda J. Hess, P.E., CFM
H & H Group Manager
Gannett Fleming, Inc.

Ms. Hess is a Hydrology and Hydraulics Group Manager and Senior Project Engineer in the Dams and Hydraulics Section of Gannett Fleming, Inc. Amanda received her bachelor’s and master’s degrees in civil engineering from the Pennsylvania State University. She has about 20 years of experience working on dams, flood control projects, and water supply systems and performing a wide range of hydraulic and hydrologic analyses. She is responsible for leading a team of engineers to perform hydrologic and 1-, 2- and 3-D hydraulic analyses for water resources projects and design hydraulic structures related to flood control reservoirs, dams, bridges, and channel improvement construction, rehabilitation, and reconstruction projects, including the design of spillways, outlet works, and stilling basins. Amanda regularly instructs courses on hydrologic and hydraulic modeling.
