76 CHAPTER ELEVEN STATE OF RESEARCH AND CONCLUSIONS Historical learning is essential to advancing our knowledge relevant to minimizing roadway embankment damage resulting from flooding. However, adequate documenting the flooding event occurrences and their effects is not commonly done as a part of DOT practice.
