Manual for Hydrologic and Hydraulic Design

The Manual for Hydrologic and Hydraulic Design has been prepared by the Maryland Department of Transportation, State Highway Administration (MDOT SHA), Office of Structures, Structure Hydrology and Hydraulics Division (SHHD), to provide guidance and direction to engineers involved in locating, analyzing, and designing bridges and culverts in Maryland. This SHHD Manual consists of two volumes. The chapters in Volume I provide an overview of SHHD design and project development procedures. Revisions to Volume I were completed in 2020. The chapters in Volume II provide detailed design guidelines and analysis procedures for the various aspects of the design of hydraulic structures. The chapters in Volume II were last revised in 2015. SHHD is planning to provide necessary updates and/or revisions to the Volume II chapters as soon as possible. In the meantime, SHHD should be contacted for any questions or clarifications.

Users should check this website regularly to verify that they are using the most current version of each chapter. A summary of any updates and edits is provided in Chapter 1 (Table 1-2). The SHHD Manual individual chapters (pdf files) are available here.

For reference, a previous version of Volume I is provided: Manual for Hydrologic and Hydraulic Design, Previous Revision
