New Results and Research Needs on Sediment Movement in Urban Drainage

Abstract

The Environmental and Water Resources Institute of ASCE has established a task committee to study the problem of sediment movements in urban drainage systems and to make recommendations for new research and for design and modeling improvements. This paper is an initial part of this effort; it addresses a review of related publications within the past 7 years. Sediments can cause sewer blockage, surcharge, early overflows, and large pollutant discharges; their removal is costly. The review of the recent literature shows that much progress on this problem has been made in Europe and that fundamental and applied research and development in the United States is urgently needed.
