This webinar was co-sponsored by ASCE's Environmental & Water Resources Institute and ASCE Continuing Education.
Instructor Information: Rollin Hotchkiss, Ph.D., P.E., D.WRE
Course Length: 1 Hour
Purpose and Background
State Departments of Transportation are in the midst of rehabilitating or replacing a majority of their culverts. Engineers now have available tools that will allow them to design culverts that will meet traditional requirements while also providing for upstream fish passage. Providing for fish passage will help restore ecosystem connectivity in the watershed, reduce downstream scour and maintenance needs, and improve overall hydraulic conditions in our nation’s smaller streams and rivers.
Participant will gain an understanding of the procedures available for prioritizing and assessing culverts for rehabilitation and/or replacement considering fish passage, know how to decide which alternative is most appropriate, and be able to access current design manuals for both cases.
- Understand the need and current objectives for providing fish passage through culverts
- Learn the terminology and design approaches currently in use to better communicate with Federal and State agencies
- Learn how culverts are prioritized and assessed for rehabilitation or replacement when considering fish passage
Civil and environmental engineers and engineering managers tasked with evaluating, designing, and installing culverts, and those involved in identifying and implementing stream mitigation projects to address construction impacts will benefit from this webinar.
Both state Departments of Transportation (DOTs) and consulting firms that support DOT design activities for fish passage and stream restoration will find this webinar beneficial.
- The fish passage picture – needs and requirements
- Prioritizing and assessing culverts for rehabilitation or replacement considering fish passage needs
