Hydraulics Manual
The Hydraulics Manual (2011 version) is now available for use in highway design.  The manual is only available for viewing and printing at this website. 
 
The manual changes are effective beginning April 2, 2012.  These changes supersede all previous versions and apply to new designs projects as of the effective.  New ODOT designed projects are those that do not have an approved DAP by the effective date.  New outsourced projects are those that do not have an executed work order contract for PE by the effective date.  However, existing projects may make use of the new changes, if agreed to by the CPM or Project Team Leader.
 
Edits within existing chapters are shown in blue highlighting.  Chapter or appendix titles highlighted in blue are new. 
 
Changes were made to chapters 3, 4, 5, 6, 7, 8, 9, 10 11, 12, 13, and 15.

Technical Bulletins
Technical Bulletins may be issued between manual updates.  Bulletins are intended to provide immediate guidance on process, procedures and design information for users until the next manual update, at which time the bulletin may be incorporated into the Hydraulics Manual.
