Answer 2

Answer:

• Dams do not last forever because sun, wind, seepage, earth settlement and other natural erosion forces slowly weaken the dam structure.

• Spillway design error (near failure of Glen Canyon Dam) Lowering of dam crest height, which reduces spillway flow (South Fork Dam) Geological instability caused by changes to water levels during filling or poor surveying (Malpasset Dam).
