An open channel flow is a flow having a free surface subject to atmospheric pressure. Open channel design is to design a channel to carry a certain amount of flow from one location to another under any provided channel geometry and topographic conditions. Parameters to define channel geometry include channel shape, cross‐sectional area, wetted perimeter, hydraulic radius, top width, and hydraulic depth. Manning's equation computes channel discharge. For open channel design, channels should be classified as nonerodible and erodible channels. For lined (nonerodible) channel design, one typically designs the channel with the best hydraulic section, where the channel section has the least wetted perimeter for a given cross‐sectional area and the channel is most hydraulic efficient. If a channel is placed in erodible material, the permissible velocity method can assure channel stability. A freeboard is recommended to prevent overtopping by surface waves and surges.
