A Compound Weir is a combination rectangular weir with a V-notch cut in it. This permits good measurements for stream with a wide range of flows. The V-notch is sized for low flow conditions while larger flows are measured with the rectangular weir. The discharge over a compound weir is calculated by simply applying the standard discharge equation for each segment of the weir to the head on that segment of the weir. The total discharge is then the sum of the discharges of each to the two segments of the weir.
