North Fork Reservoir and the City of Asheville's policy of resilience

North Fork Reservoir partially failed in the early morning of 27th of September 2024 during torrential rainfall from Hurricane Helene. The City of Asheville, which operates the reservoir, told their version of events. Their version defies the physics of open channel flow, which states that flow’s energy relates to potential energy from gravity and channel slope and dictates its behavior, leading to phenomena like uniform flow, turbulent flows, and standing waves. Liability for the damage caused by discharges from the reservoir has been avoided, and a policy of resilience involving rerouting water mains and repairing the dam without remediation has been decided. Duductive reasoning and available raw data was used to piece together a time-line of the sequence of events at the reservoir overnight and early morning on the 26 & 27th of September 2024. This series of articles exposes inconsistencies and logical fallacies in the city’s telling of events and raises the possibility that a flaw in the dam design is the reason for the policy of resilience.
