Office of Structures Manual for Hydrologic and Hydraulic Design
The Manual for Hydrologic and Hydraulic Design was prepared by the State Highway Administration (SHA) Office of Structures(OOS) Structure Hydrology and Hydraulics Division (SHHD), to guide and direct engineers involved in locating, analyzing and designing bridges and culverts in Maryland.
This SHHD Manual consists of two volumes. The chapters in Volume I (Chapters1-6) provide an overview of SHHD design and project development procedures. Revisions to Volume I were completed in 2020 and will be further updated in 2025.
The chapters in Volume II provide detailed design guidelines and analysis procedures for the various aspects of the design of hydraulic structures. These chapters (Chapters 7-14 and 19) were revised between 2007-2016. SHHD is updating and revising the Volume II chapters ,and the documents will be posted as they are completed. In the meantime, check this website regularly to verify that you are using the current version of each chapter and contact OOS SHHD for any questions or clarifications.
