<br />Lesson 5 <br /> <br />Culvert Failures - Participant Workbook <br /> <br />CASE STUDY III <br /> <br />This study shows failures (or perhaps potential failures) that became evident in the <br />inspections following the flood. Some may have occurred during the flood while others <br />have been slowly becoming a problem over a longer time period. The culverts shown <br />are corrugated metal pipes, concrete pipes and concrete boxes. Each failure is rather <br />unique but seems to be related. Remember that the chief engineer will be meeting with <br />the govemor shortly. <br /> <br />Within the next twenty minutes, review the attached photographs, background material, <br />and <br /> <br />1. Establish the cause(s) of the failure. <br /> <br />2. Develop a way to prevent such failures in the future. <br /> <br />3. Select a spokesperson to summarize your findings to the "Chief Engineer." <br /> <br />5-12 <br /> <br />, <br />, <br />I <br />il <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />t <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
