Online Course: HEC-HMS Modelling

Use hydrological data to provide realistic simulations of the rainfall-runoff process

The Hydrologic Modeling System (HEC-HMS) is a free program developed by the U.S. Army Corps of Engineers. HEC-HMS simulates the complete hydrologic processes of dendritic watershed systems including infiltration, unit hydrographs, and hydrologic routing. Applicable and designed for almost all regions of the world, HEC-HMS offers flexibility so that each hydrologic process has multiple modelling techniques to create a fully customised end model.

This live and interactive course will introduce the purpose, features and limitations of HEC-HMS, by running and creating a basic model case study, with your expert presenter describing the software structure and menus of HEC-HMS.

Date: Thursday, 7 November 2019 - Thursday, 14 November 2019

Time: 10:30am (Australia/Sydney; find your local time)

Cost: AUD$295 (about $200 US dollars)

Please join us for this interactive online course (see dates below), covering HEC-HMS, a free rainfall-runoff program developed by the U.S. Army Corps of Engineers. HEC-HMS also accounts for evapo-transpiration, snowmelt, and soil moisture and can be used in conjunction with other software for studies of water availability, urban drainage, flow forecasting, urbanisation impacts, reservoir spillway design, flood damage reduction, floodplain regulation, and systems operation.

Course Format: 

2 live and interactive sessions of two hours each

  • Thursday, 7 November, 10:30am -12.30pm (Sydney Time)
  • Thursday, 14 November, 10:30am – 12.30pm (Sydney Time)
  • Sessions are recorded & uploaded to the learning platform (within 24hrs after session) if you cannot attend live.

Session 1, Thursday, 7 November, 10:30am -12.30pm (Sydney Time)

  • Background to HEC-HMS software– what can it do and limitations
  • Explain the software structure, where to find menus, input data, run model and read the results.
  • Develop a simple case study to demonstrate from the beginning to end how to generate a flow hydrograph for multiple basins and extract them to reports or to other software for hydraulics or similar.

Homework to complete before session 2. Follow the recording for review of session 1.

Session 2, Thursday, 14 November, 10:30am – 12.30pm (Sydney Time)

  • Discuss any issues faced from homework case study or session one.
  • Explain some advanced menus and elements to utilise features such as storage ponds, soakage losses and pipes.
  • Further develop a case study to include features to do after the session.

A short quiz will be on the learning platform, to cement attendees understanding.

This course covers:

  • Overview of Precipitation-Runoff Processes
  • Rainfall Loss Rates Computation
  • Channel Routing
  • Basin Model Manager
  • Meteorologic Model Manager
  • Control specifications and time-series data
  • Conducting simulation runs
  • Data interpretation and calibration
  • Exporting results for use in HEC-RAS

Outcome: On completion of the course attendees will be issued with a Certificate of Participation.
