Why don’t we channelize creeks to prevent flooding?

May 9, 2024

Creeks naturally meander to distribute energy, slow stormwater and prevent bank erosion. Channelization typically increases flow and prevents flooding in one area. However, with an increase in velocity, the stream compensates by eroding stream banks and depositing sediment in other areas to regain balance and its natural shape. Historically, channelization has caused habitat loss and water quality degradation.
