Guide to the Inspection of Embankment Dams
Credits: 5 PDH
PDH Course Description:
This course will introduces the basic guidelines of dam inspection according to the FEMA. It is estimated that there are about 75,000 dams in the US, many of which are reaching the end of their expected useful lives. With the inventory of aging dams, maintenance and inspection become more critical. At the same time, the useful life of a many new dams may be extended by regular maintenance of deficiencies which are discovered during routine inspections.The content of this course is a workbook titled “Inspection of Embankment Dams” published by FEMA and a video intended to supplement the workbook. Engineers, dam owners, dam safety officials and maintenance contractors will gain an understanding from this course of the areas to be inspected on an embankment dam according to FEMA recommended practices. Additionally, this course could be useful as a guide for training to an embankment dam inspection.
If you are new to dam safety inspection, the material presented in this course will provide important background information. The discussion of the inspection process is designed to provide the inspector with guidance for conducting a comprehensive inspection of a dam embankment.
