Time Units

•Sized by maximum depth of flume

•Approach is preferably rectangular, matching width and depth for distance 3 to 5 times the depth of the flume

•May be installed in channels under partial submergence (ratio of downstream level to head). Typical errors are:

•1% @ 30% submergence

•3% @ 50% submergence

•For rated flows under free flow conditions, the head is measured at a point downstream from the flume entrance
