62 Dams Collapsed in a Single Night One After One | The Banqiao Dam Disaster

Описание: 62 Dams Collapsed in a Single Night — The Banqiao Dam Disaster

In August 1975, a catastrophic engineering failure resulted in the third-deadliest flood in recorded history. This investigation examines the structural and systemic collapse of the Banqiao Dam and 61 other reservoirs across China’s Henan Province following the impact of Typhoon Nina.

While official records initially suppressed the scale of the disaster, forensic analysis reveals a chain reaction of failures—from inadequate spillway design to the "domino effect" of cascading dam breaches. We analyze the data behind the 1-in-1,000-year storm that produced over 1,060mm of rain in just 24 hours, far exceeding the "Iron Dam’s" design specifications.

Investigation Overview:

The Design Flaw: An analysis of why these Soviet-style earthfill dams were optimized for irrigation storage over flood safety margins.
The Chain Reaction: The forensic sequence of how the Shimantan Dam breach triggered the collapse of 61 downstream structures.
The Data Gap: Examining the meteorological and communication failures that left 10 million people without an early warning system.
The Aftermath: A statistical review of independent fatality estimates and the total structural reconstruction of the Huai River basin.
Forensic Focus: This documentary tracks the transition from a "one-in-one-thousand-year" design standard to a total systemic breakdown. We examine the archival evidence of suppressed warnings and the engineering reality of earthen embankment overtopping.

About Mystery Axiom: We provide evidence-based investigations into historical failures, structural anomalies, and unexplained mysteries. Our focus is on archival evidence, logic, and forensic-style reporting.
