Excerpt from Studies of the Use of Pervious Fence for Streambank RevetmentThe design of a pervious stream bank revetment has been made generally by cut-and-try methods during at least the cuarter century of its active use. This pragmatic solution is reflected in the older composite revet ments in Los Angeles County, California, which show the original fence with the attachments and modifications that have been made as the result of flood damage.To obtain data on the construction and behavior of a pervious fence, many field installations in Los Angeles and Orange Counties were inspected in the dry season and during the small run-off period of the 1946-47 water year. The process of maintenance of a revetted channel of this type is a continuous one so that in many cases the flood damage of previous storms had long been repaired and the evidence of its behavior obliterated. Thus it was necessary to study some of the records and pictures taken of the channel control operations and to talk with the engineers, foreman, and patrolman who worked and observed during the periods of flow. 'projects under construction were visited to obtain an understanding of the current construction methods and machines used.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
