- Abstract
- This report deals with the development of probabilistic performance data on levees and levee systems subject to multiple natural hazards. Two types of levees are considered: dry levees, which are in use only when a river overbanks, and wet levees, which are almost continually holding back water, although the water level may vary considerably. A levee system fails when the protected area is flooded as a result either of water crossing the line of the levee from the riverside or water not being able to cross from the landside. Reasons for the two types of failure are examined and the development of the three-dimensional stability model and its use in studying the effects of different hazards are considered.
