This 3-hour interactive online course provides procedures for the design of riprap revetments to be used as channel bank protection and channel linings on larger streams and rivers (i.e., having design discharges generally greater than 50 cfs). Procedures are also presented for riprap protection at bridge piers and abutments.
The emphasis in this course is on the design of rock riprap revetments. Other portions of the course cover the recognition of erosion potential, and erosion mechanisms, and riprap failure modes. It includes several design examples of use of the procedures. The course is based on current guidance from the Federal Highway Administration.
It will be necessary to download the pdf file from the FHWA website to view some of the figures and charts referenced in this course, and to view the photographs.
Vector Solutions has a long history of providing industry-specific content for its customers. While this course and its content remain accurate and functional within our systems, the look and feel may not match our more modern offerings.
At the conclusion of the course, you will:
- Be able to identify the four different failure modes for riprap and will understand what causes each failure mode.
- Understand the different types of riprap, including rock riprap, rubble riprap, wire-enclosed rock, pre-formed block and grouted rock, including the advantages and disadvantages of each type.
- Understand how flow type, section geometry, channel bends and flow resistance affect the design of riprap revetments.
- Understand how to determine the longitudinal and vertical extent of riprap revetments and the necessary toe depth.
- Understand how to compute the necessary size of rock, gradation and layer thickness to use for riprap revetments.
- Understand how to compute whether a filter is necessary under the riprap and how to design a filter.
This course includes a test at the end of each section to gauge your understanding of the material.
