The first edition of the Model Drainage Manual was published in
1991. This second edition of the manual was produced in
cooperation with the Transportation Research Board, National
Cooperative Highway Research Program. This edition contains
updated procedures
and uses metric units.
This comprehensive
drainage manual provides guidance on most aspects of highway
drainage. Design theories, concepts, manuals, policies and
procedures are condensed and written for use by the designer.
Where appropriate, relevant existing AASHTO guidelines are
given and/or referenced. The manual has been developed to
give the designer a basic working knowledge of hydrology and
hydraulics complete with example problems. All basic design
elements are included so that the designer can design highway
drainage with minimal assistance.
The manual is organized in the
following chapters:
(1) Introduction; (2) Legal Aspects; (3) Policy;
(4) Documentation; (5) Planning and Location; (6) Data Collection;
(7) Hydrology; (8) Channels; (9) Culverts; (10) Bridges; (11)
Energy Dissipators; (12) Storage Facilities; (13) Storm Drainage
Systems; (14) Pump Stations; (15) Surface Water Environment;
(16) Erosion and Sediment Control; (17) Bank Protection; (18)
Coastal Zone; (19) Construction; (20) Maintenance of Drainage
Facilities; and (21) Restoration. The Appendix contains a
Glossary.
This new 2000 Metric Edition of the Model Drainage Manual combines the 1999 Metric Edition and Appendices 7-E on "Wetland Hydrology, the Water Budget" and 15-G on "Wetland Creation and Restoration."
