Mosul Dam: Is it the Most Dangerous Dam in the World?

Mosul Dam is an earth fill dam, with a storage capacity of 11.11 km³ constructed on highly karstified gypsum beds alternating with marl and limestone. After impounding in 1986, seepage locations were recognized. The dam situation now indicates that it is in a state of extreme relative risk. If it fails, then 6 million people will be affected and 7202 km² area will be flooded. Grouting operations will elongate the life of the dam but will not solve the problem. Building a protection dam downstream will be the best measures to secure the safety of the downstream area and ist’ population.
