#3 H&H Essentials: Flow Routing

Australian Water School Develop design hydrographs and calibrate model results to observed flow records

Target Audience

The course is designed to cater for engineers and non-engineers alike, with a range of provided background materials that make the course suitable for both beginners and experienced professionals seeking a refresher for the underlying concepts behind hydrologic and hydraulic modelling applications.


Hydrologic and hydraulic modelling software packages are becoming increasingly powerful, with impressive abilities to run countless iterations and display realistic flood inundation scenarios; however, a basic understanding of the underlying concepts is key in correctly interpreting, applying and presenting results. Working in collaboration with industry and academic experts the Australian Water School (AWS) has created the Hydrology and Hydraulics (H&H) Essentials training series, comprised of 8 individual intensive 3-hour courses with each course flowing into the next enabling attendees to build their skills piece by piece through every course. This course is part of the H&H Essentials series (click here to register for the ENTIRE series).

Throughout the course attendees will be shown practical working examples, learning hands-on how to use and apply different rainfall-runoff approaches, leading to an increased understanding of confidence limits, probability, and uncertainty in the analysis and application of flow routing.

Take sessions anytime, at your own pace, with unlimited course access for 4 months. Attendees earn CPD hours/points with professional organisations for at least 5 hours per course (therefore 40+ hours for the series).

Key Concepts/Topics

  • Types of hydrologic models: rainfall-runoff routing vs rain-on-grid/direct precipitation
  • Transform methods vs routing methods
  • Unit hydrographs and kinematic wave models
  • Lag, modified Puls, and Muskingum-Cunge flow routing
  • Modelling and designing detention and storage systems for flow attenuation
  • Generating a probable maximum flood from the probable maximum precipitation

Learning Objectives

In this 3-hour intensive training course attendees will increase their knowledge of rainfall-runoff techniques for generating and routing flow, including the sensitivity of peak flow results to the selected parameters. On completion of the course attendees will understand:

  • How to select a rainfall-runoff model
  • Calibrating peak flow rate, lag time, and flow volume to observed results
  • How to apply ensemble and Monte Carlo approaches
  • How to conduct and interpret sensitivity analyses
