The Highway Drainage Guidelines provides a consolidated overview of highway hydraulic design and discusses possible hydrology problems in the following areas: Hydraulic Considerations in Highway Planning and Location; Hydrology; Erosion and Sediment Control in Highway Construction; Hydraulic Design of Highway Culverts; The Legal Aspects of Highway Drainage; Hydraulic Analysis and Design of Open Channels; Hydraulic Analysis for the Location and Design of Bridges; Hydraulic Aspects in Restoration and Upgrading of Highways; Storm Drain Systems; Evaluating Highway Effects on Surface Water Environments; Highways Along Coastal Zones and Lakeshores; Stormwater Management; Training and Career Development of Hydraulics Engineers; Culvert Inspection, Material Selection, and Rehabilitation; Guidelines for Selecting and Utilizing Hydraulics Engineering Consultants.

External Works Roads and Drainage: A Practical Guide bridges the gap between theory and practice in building, construction and civil engineering, providing practical guidance, and the knowledge required 'on the job'. This comprehensive book includes sections on legislation, environmental issues, surface water, highway and foul drainage design, road and pavement design, and external works.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

This circular provides a comprehensive and practical guide for the design of storm drainage systems associated with transportation facilities. Design guidance is provided for the design of storm drainage systems which collect, convey, and discharge stormwater flowing within and along the highway right-of-way. Methods and procedures are given for the hydraulic design of storm drainage systems. Design methods are presented for evaluating rainfall and runoff magnitude, pavement drainage, gutter flow, inlet design, median and roadside ditch flow, structure design, and storm drain piping. Procedures for the design of detention facilities are also presented, along with an overview of storm water pumping stations and urban water quality practices. This edition presents a major change in the methodology discussed in Chapter 5 for designing channels and in Chapter 7 for calculating energy losses in storm drain access holes.

This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."
