Design of Urban Highway Drainage - The State-of-the-Art

摘要

This manual represents the state-of-the-art for the design of urban highway drainage. Historical practice has involved a philosophy of intersecting, collecting, and disposing of stormwater runoff as rapidly as possible. The cumulative effects of such past concepts of urban storm drainage have been a principal cause of increased frequency of downstream flooding, often accompanied by diminishing groundwater supplies as direct results of urbanization; or they have necessitated development of large-scale downstream engineering works to prevent flood damage. Stormwater management diminishes these problems by the use of integral and interrelated systems of collection, storage, treatment, and disposal of stormwater. This manual provides information necessary for the design of individual components as well as interrelated stormwater systems.
