The Morvi dam failure was a dam-related flood disaster which occurred on August 11, 1979 in India. The Machchu-2 dam, situated on the Machhu river burst sending a wall of water through the town of Morvi in Indian state of Gujarat.[1] Estimates of the number of people killed vary greatly ranging from 1800 to 15000 people.[2][3]

The failure was caused by excessive rain and massive flooding.[citation needed] The spillway capacity provided for 5663 m³/s. But the actual observed flood during intense rainfall became 16307 m³/s, 3 times what was designed - that caused the collapse of the dam. Within 20 minutes the floods of 12 to 30 ft (3.7 to 9.1 m) height inundated the low-lying areas of Morvi industrial town located 5 km below the dam. During reconstruction of the dam the capacity of the spillway was increased by 4 times and fixed at about 21,000 m³/s. [4]
