#7 H&H Essentials: Pipe Flow and Hydraulic Structures

Australian Water School Learn hands-on how to compute pipe flow for culverts and storm drain networks

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 AWS H&H Essentials series (click here to view the ENTIRE series).

In this 3-hour intensive training course, the experts will guide attendees through the computation of pipe flow. Throughout the course attendees will be shown practical working examples, learning hands-on how to compute pipe flow for culverts and storm drain networks, leading to an increased understanding of the underlying principles governing flow in closed conduits.

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

  • Reynolds Number and Moody diagrams for pipe flow
  • Energy gradient, hydraulic gradient, and losses
  • Pipe networks, pumps, and turbines
  • Inlet and outlet control for culverts
  • Orifice flow and weir flow for bridges
  • Blockage of hydraulic structures
  • Empirical equations and nomographs for hydraulic structures

Learning Objectives

Attendees will increase their knowledge of modelling techniques for closed conduits and the sensitivity of predicted results to the selected parameters and learn:

  • How to determine pipe capacity
  • How to model storm drain networks vs individual culverts
  • How to compute inlet and outlet losses
