Hydraulics and Hydrology training course manual

Highway Runoff Manual training workshop

The Highway Runoff Manual (HRM) is WSDOT’s primary source of stormwater planning and design requirements for highway-related work. The HRM Training Workshop is a certification course that is for WSDOT, local agencies, and consultants who do stormwater work on WSDOT Right of Way. It is targeted toward stormwater engineers, designers, and environmental professionals whose work on transportation-related stormwater issues requires use of WSDOT’s 2019 HRM.

As an obligation of WSDOT’s National Pollutant Discharge Elimination System (NPDES) Municipal Stormwater General Permit, this training is required for anyone that designs new stormwater Best Management Practices (BMPs) on WSDOT ROW, modifies an existing stormwater BMP on WSDOT ROW, or where a stormwater BMP is designed or modified and will be turned back to WSDOT for ownership. If you already have a 2014 HRM certificate number, there is a separate 2019 HRM Update Training so that you can receive your 2019 HRM certificate number.

Participants are required to attend every day of the training and pass the final exam to receive a 2019 HRM Certificate of Completion number. This certification number is valid until the next version of the HRM, which is expected in 2024. Any major HRM updates, supplements or trainings will be announced on the Highway Runoff Manual web page and through the HRM listserv.

WSDOT maintains a database of all professionals who have successfully completed the training. This database may be referred to by WSDOT when making future work assignments, when reviewing future requests for proposals, and it may be used in the proposal ranking criteria for future projects.

2022 Fish Passage and Stream Restoration design training (online)

In partnership with the WDFW and the Tulalip Tribe, WSDOT has put together the 2022 Fish Passage and Stream Restoration Training. This training is intended to inform water resource practitioners on the purpose and process of fish passage barrier corrections as they relate to WSDOT roadway crossings. Participants who complete the full training and pass the final exam will be issued a 2022 FPSRD certificate number. This certificate number will be required starting January 31, 2021 by all authors of the Preliminary and Final Hydraulic Design (PHD/FHD) reports written for WSDOT projects.

Training overview: This training is composed of 14 separate video modules, each of which focuses on a different aspect of the purpose and process of fish passage projects delivered by WSDOT. Participants must watch all module videos before seeking certification for this training. Links to these module videos and their descriptions are provided below.

Certification: In order to receive a FPSRD certificate number, a participant is required to view all 14 module videos, and pass a comprehensive exam. Once a participant has viewed all module videos, send an email to Fish Passage Training to receive a link to the exam. The exam consists of 50 questions with several from each of the modules, and a score of at least 70% is required to pass. After successful completion of the exam, the participant will receive a 2022 FPSRD certificate number. This certificate number will be required starting January 31, 2021 by all authors of the Preliminary and Final Hydraulic Design (PHD/FHD) reports written for WSDOT projects.

Training materials and resources: The resources listed here are intended to be used in conjunction with the training modules below. Please contact HQ Hydraulics to ensure you are using the most current version of these files for your project.

MGSFlood productivity training workshop for WSDOT projects

This training provides step-by-step instructions for stormwater modeling of flow control Best Management Practices (BMPs) and some runoff treatment BMPs for western Washington WSDOT projects. This training walks the participant through the setup and use of the continuous simulation model software MGSFlood. This training is targeted towards new and intermediate stormwater designers.

This training incorporates Highway Runoff Manual (HRM) stormwater policies and design checks into the stormwater modeling process. The training workshop really focusses more on how to do stormwater modeling for WSDOT projects and less on the “why”. The participant will also learn how to develop model inputs and how to read the model output to verify compliance with HRM stormwater policies.


Scheduled training dates TBD.

Please use the MGSFlood continuous simulation modeling software for this training if you want to do calculations as we work through the example problems. The training will not provide the participant with a license or copy of MGSFlood. WSDOT employees can download the MGSFlood software from the Software Center from their start menu. Other non-WSDOT participants can download a free trial version of the software from the MGSFlood website.

Please download a copy of the WSDOT Flow Control Inputs Spreadsheet (XLSX 67KB).

StormShed3G Beginner Training Workshop

WSDOT uses StormShed3G to design conveyance systems including pipe, storm sewer and ditches. The class will give students general knowledge of the StormShed3G software and its capabilities along with hands on experience. Examples are used to teach students how to set up basins, design ditches and networks, as well as how to determine the correct design storm events. BMP design guidance from the HRM is included in the training material. The StormShed3G Beginner Training Workshop will use GoToWebinar.  

Scheduled training dates 

Tuesday, December 6, 2022 from 8:00am – 4:30pm

Register here for the StormShed3G Beginner Training Workshop

Please note attendees using a WSDOT computer or WSDOT laptop need to contact WSDOT IT staff (360-705-7050) to get StormShed3G installed.

WSDOT will not provide StormShed3G for non-WSDOT computers or non-WSDOT laptops. Attendees not using a WSDOT computer or WSDOT laptop will have to contact the software vendor at Engineous.com to purchase a copy of StormShed3G. It is strongly recommended, but not required to have StormShed3G for the training.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
