This publication adopts a whole-life approach to the design and operation of culverts, with a focus on asset management, reflecting changes that have occurred in the business of asset management over the past 10 to 15 years. It also addresses the management of culverts.

A new guide by the Environment Agency, this text offers information and advice on the design and management of trash and security screens upstream of culverts in England and Wales.

This publication contains clear and consise guidelines for the hydraulic design of culverts and describes the hydraulic behaviour of culverts in as simple a form as is consistent with the complexities of their actual behaviour.

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.

The manual provides information that will enable users to conduct field test and relate the data to the design, and also to design a range of types of infiltration system.
