Fragility Curves – Embankment Dam Overtopping • Often initially assume that any overtopping leads to dam breach • Fragility curves can be developed – Team should consider carefully and document reasoning behind curves – For a given depth of overtopping, a range of values and a best estimate should be developed – Many factors to consider: 31
