A Langemann gate that can be used as a check on the canal <br />and as a flow measurement structure as well. <br /> <br /> <br />Figure 8. A "duck bill" check structure is shown here. This type of check <br />is useful in maintaining a fairly constant upstream water surface <br />elevation and excess flows are accommodated by a long crested <br />weir. Although the screw gate is not automated with SCADA, the <br />wet wells upstream and downstream have been installed in <br />anticipation of future SCADA implementation. <br /> <br />Aqua Engineering, Inc. <br />November 17, 2004 <br /> <br />Canal Modernization Study <br />- 16- <br />
