The toe of Leshan Giant Buddha was flooded. Why hasn't there been a big flood since it was built?

The toe of Leshan Giant Buddha was flooded, and Xichuan suffered the biggest flood since 1984. Sichuan has launched a Class I emergency response to flood control. Because there was no such continuous heavy rainfall after the completion of Leshan Giant Buddha, there was no major flood.

Due to the continuous heavy rainfall, the giant Buddha at the intersection of Minjiang River, Qingyi River and Dadu River in Leshan suffered a rare flood disaster. This is the first time that Leshan Giant Buddha has been flooded to its toes since 1949. At present, Leshan Giant Buddha has closed the scenic spot, and all aspects of the scenic spot are investigating potential safety hazards. Relevant departments have taken relevant emergency measures to transfer tourists to safe areas and solve the problem of food and clothing for tourists.

Flood refers to the phenomenon that the water level of rivers, seas and lakes rises sharply due to a large amount of precipitation, melting of ice and snow, storm surge and other reasons. The flood in Sichuan was caused by heavy precipitation. Due to the westward movement of tropical high, rich water vapor conditions are brought, and water vapor continuously moves eastward to the basin. Due to the topography of Sichuan basin, the airflow was forced to rise continuously, which led to heavy precipitation in Xichuan basin. The precipitation intensity is large, the duration is long, and the precipitation is large. There has never been such a strong precipitation since the Leshan Giant Buddha was built. Heavy rainfall caused the river water level to rise beyond the safe area, causing floods and causing floods in the Giant Buddha.

This heavy precipitation weather may continue, so it is necessary for all relevant departments to prepare for flood control, do a good job in emergency rescue of dikes, dams and gates in flood season, and dispatch nearby reservoirs. Residents in Xichuan area pay attention to weather forecast and early warning, prepare for flood control, pay close attention to flood information during flood season and obey the unified arrangement of flood control headquarters; First aid measures such as life jackets can be prepared at home, and sandbags can be placed in low-lying places. Residents who are not at home should not go into the water in person and avoid disasters in high mountains and canyons. Pay attention to the low-lying areas of the road, which may be deep water.
