A debris jam is a blockage in a river or stream caused by accumulated materials such as fallen trees, branches, and other organic matter. This buildup can obstruct the flow of water, leading to localized flooding and changes in the river's course. Debris jams often occur during heavy rainfall or after storms when vegetation is uprooted. These jams can impact ecosystems by creating new habitats for wildlife, but they can also pose risks to human infrastructure. If not managed, a debris jam can lead to increased erosion, damage to bridges, and other structures, making it important for local authorities to monitor and address these situations promptly.
