Methods to Control Fine-Grained Sediments Resulting from Construction Activity,

摘要

Standard erosion and sediment control measures are usually effective for preventing the runoff of the total sediment load. The effectivenes of these standard techniques,however,has been found to be relatively poor with regard to preventing the runoff of the fine-grained fractions,such as the silts and clays. The objective of this study was to research practical,cost-effective methods which would help to reduce specifically the fine-grained sediment pollution derived from construction activities. The prime consideration during this study was the use or adaptation of existing technology,as described in the current literature or data,to the fine-grained sediment pollution problem.
