Rock sizing resources

This website presents a compilation of background resources to accompany the 2021 Australian Water School webinar covering the ancestry of Australian rock sizing equations (3:21) and using the Riprap Calculator in HEC-RAS Version 6.1 (31:40).

Following are some additional resources highlighted in the webinar:


Our 2021 webinar builds on the Australian Water School’s 100th webinar, “Rocking It!” which was held in 2020 and covered using hydraulic modelling results for rock sizing, presenting a range of riprap sizing methods, including the application of the FHWA toolbox.

Here are some additional resources covered in the presentations and Q&A session:

  • List and links to FHWA HDS and HEC publications (Hydraulic Engineering Circulars) and HEC software documentation (Hydrologic Engineering Center)

 

 


Thanks to everyone who filled out the poll questions during the webinar. Here are the results:

Great to see that squashed cars (or “Detroit Riprap“) got a big fat goose-egg…perhaps we have made some improvements in environmental consciousness after all!

Finally, here’s an all-important poll question that we left out. Take the live poll and check the results to see the consensus…or lack thereof:


What’s the correct spelling?

Rip rap
Riprap

Thanks for your interest and for your feedback – you rock!
