Book Description
An empirical method for scour depth estimation is developed based on radius/width and aspect ratio. The thickness of the before-launch section controls the rate at which rock is released and should be 2.5 to 4.0 times the thickness of the bank protection revetment Tau for gradual scour and 2.5 to 3.0 Tau for rapid scour found in impinged flow environments. Riprap size for gradual scour is the same for both launched riprap and riprap placed by standard construction methods. Stone volume requirements are presented as a function of scour depth and whether the launch section is placed in the dry or underwater. Gradations having D85/D15> 2 are recommended for launched riprap sections to prevent leaching of bank material through the launched riprap. (MM).

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 822: Evaluation and Assessment of Environmentally Sensitive Stream Bank Protection Measures evaluates and assesses existing guidelines for the design, installation, monitoring, and maintenance of environmentally sensitive stream bank stabilization and protection measures, and develops quantitative engineering design guidance for selected treatments. Updated design guidelines for three widely used treatments are presented: live siltation and live staking with a rock toe, vegetated mechanically stabilized earth, and vegetated rip rap. A compendium of field data, documentation, and photographs complement the report. The compendium is available as a DVD and available for download from TRB’s website as an ISO image."--Publisher’s description.

Book Description
The purpose of this document is to identify and provide design guidelines for bridge scour and stream instability countermeasures that have been implemented by various State departments of transportation (DOTs) in the United States. Countermeasure experience, selection, and design guidance are consolidated from other FHWA publications in this document to support a comprehensive analysis of scour and stream instability problems and provide a range of solutions to those problems. The results of recently completed National Cooperative Highway Research Program (NCHRP) projects are incorporated in the design guidance, including: countermeasures to protect bridge piers and abutments from scour; riprap design criteria, specifications, and quality control, and environmentally sensitive channel and bank protection measures. Selected innovative countermeasure concepts and guidance derived from practice outside the United States are introduced. In addition, guidance for the preparation of Plans of Action ...
