SECTION 111 - OPEN CHANNELS

Critical depth, dc - the depth of flow at which the specific energy is a minimum for a given flow rate and channel cross shape, and a unique relationship exists between depth and specific energy. Normal depth, dn - the depth at which uniform flow occurs when the discharge rate is constant. Friction and gravity forces are in balance.
