La sedimentation manual

urban design and erosion and sediment control at the same time, and as early as possible in the planning process. Major site drainage issues and topographic and hydrologic variables are similar for both phases of development, and have the same objective of waterway protection. This manual establishes the Los Angeles County Department of Public Works' sedimentation design criteria. The procedures and standards contained in this manual were developed mostly by the Hydraulic/Water Conservation Division of Los Angeles County Department of Public Works as the need arose to design erosion control structures, sediment retention.

A supplement to the classic Sedimentation Engineering (Manual 54), this new volume not only documents the evolution of the field over a year period, but also reports on the state of the practice. This manual addresses new topics in physical processes, measurements, modeling, and practice, mainly in the context of rivers and inland water bodies. According to the cut-off depth table in the Hydraulic Design Manual, levee toe- down is 15 ft (for a curved reach and a velocity of 12 fps), therefore, use 15 ft cut- off depth. 2.
