Controlled surface hydrology

Controlled surface hydrology refers to the addition of activities and/or structures (e.g., bunds, pumps, etc.) consistent with water storage usage where surface hydrological flows are controlled. Typically, wetlands with controlled surface hydrology are semi-enclosed structures with pump facilities.

• Controlled surface hydrology creating an artificial wetland
• Controlled surface hydrology in a channel
• Controlled surface hydrology outside a channel

Controlled surface hydrology observed in a channel converts the wetland to a palustrine or lacustrine system. Typically, these are used for water storage and flows into and out of the wetland are mechanically controlled.
