Abstract: Abstract: This study was conducted in response to a problem definition workshop held in April 1984 for the Repair, Evaluation, Maintenance, and Rehabilitation (REMR) Research Program Work Unit No. 32274, "Rehabilitation Alternatives to Control Adverse Effects of Levee Underseepage." The following research need was determined to have one of the highest priorities: Emergency flood fight guidance for observing underseepage and employing remedial actions. Documented in this report are the basic levee inspection responsibilities and flood fighting techniques of the Mississippi River Valley Districts (Rock Island, St. Louis, Memphis, and Vicksburg) and the Levee Boards. The need for a consistent terminology for the severity of underseepage, better flood fight training for young engineers, and better mobility for inspection were the main problems identified in this report. The following terminology is recommended as a standard to describe the severity of underseepage: Light - area is wet.; Moderate - running water is observed.; Heavy - pin boils (small pipe openings without sand cones) with running water.; Sand boils - any pipe opening with sand cones.; Large boils - sand boils with pipe openings 12 inches or more in diameter (size described by diameter of pipe opening). Personnel interviewed, documents collected from CE District offices, and a list of questions related to inspection for underseepage during floods are included in Appendices A, B, and C, respectively.
