Course Contents

The course will cover 3 main topics across 3 parts.

Part 1 

  • Introduction to HEC program architecture and overview of HEC-HMS program structure
  • Overview of the HEC-DSS data storage system, and how HEC programs interact with it.
  • Downloading and preparing terrain data for HEC-HMS and using HEC-HMS catchment delineation tools to create a hydrological model
  • Downloading and preparing meteorological data for HEC-HMS
  • Creating and computing a simulation run
  • Viewing model results

Part 2 

  • Downloading and preparing observed, gauge data
  • Applying gauge data to the hydrological model
  • Calibration using HEC-HMS parameter optimisation for storm events
  • Calibration using long term continuous simulation and flood frequency analysis using HEC-SSP
  • Overview of parameters (loss, transform, reach-routing)
  • Sensitivity analysis using HEC-HMS Monte-Carlo

Part 3

  • Downloading and preparing gridded rainfall data for an Australian catchment
  • Using ARR gridded data within HEC-HMS
  • Brief introduction to Storm Injector by Catchment Simulation Solutions for ARR 2019
    • Importing basin model into Storm Injector
    • Downloading point and gridded ARR 2019 data
    • Computing peak flow, volume, and time to peak
    • Interpreting box charts for adopted temporal pattern and critical duration
    • Plotting hydrographs and rainfall hyetographs
    • Post storm-injector modifications to hydrological model


  • 9+ hours of recordings with unlimited access for 30-days
  • Pre-and-post-course materials to go through via the AWS learning platform
  • Exercises between the 3 parts
  • Manual of the course and working model download/s
  • Ability to ask questions to the presenters at anytime through the learning platform
  • PDF manual of the course. The manual is recommended for ongoing use
  • Any working models/ software’s necessary as per instructions in individual course, downloaded from the learning platform before starting the recordings
  • Some courses have Exercises / homework to complete between courses
  • Pre-reading and viewing materials
  • Attendees earn CPD hours/points (ie with Engineers Australia) for at least 14 hours for the entire course.
