WATERMAN TILTING WEIR (OVERSHOT) GATESare an overflow-type gate used to control levels in canals, basins and other agricultural, municipal and industrial applications.

The basic gate design uses a rectangular panel mild steel panel that is mounted to a piano hinge at the forward bottom edge of the gate leaf.    This leaf is raised and lowered using a cable drum hoist to control the upstream water level.

Overshot gates (also known as pivoting weir gates) are used to control upstream water levels. Versatility, efficiency, and safety are the primary reasons the Fresno Overshot Gate is the method of choice for municipal, agricultural, and industrial canal water control.

Auke Water’s parent company Fuda Group have serviced the water industry in China for 20 years constructing large dam gates in their Jiangsu factory. To expand their product line Fuda created Auke Water, a company who would be dedicated to providing intelligent irrigation solutions within China and East Asia. Auke realised that it did not have the technical experience to produce high quality irrigation solutions, although it had sufficient manufacturing experience to produce quality gates.

After licensing the initial gates designs from a well-known international irrigation gate manufacturer ICS worked with the Auke engineers to produce a range ofhigh qualityaluminium gates that are capable of serving all the typical irrigation canal operations. The range of gates includes overshot regulators capable of accurate in channel flow measurement, undershot regulators and metered farm offtakes.

ICS worked with the electrical engineers to develop standard control systems that are installed on the gates to facilitate the automatic operation, telemetry, local user interface, and power supply. The control systems use all commercially available off the shelf hardware and software which is important to ensure the clients can support and maintain their system economically.

ICS worked with Auke to develop two methods of internet connectivity for their automated gate systems. Two systems were developed so Aukeisable to provide their clients with commercial competitive IoT communication systems for both small projects (e.g less than 40 sites) and large projects. Having every site remotely connected to the internet provides Auke and their clients with a massive advantage when it comes to commissioning, supportandmaintenance. Any updates or troubleshooting that the sites require after installation are easily completed by Aukes engineers without the need to travel tosite, which significantly reduces the maintenance cost and reduces downtime.

ICS’s experience with designing and manufacturinghigh qualityaluminium and stainless steel water gates allowed Auke Water to fast track their in-house design and manufacturing capabilities. ICS trained the engineers and factory personnel on the details of quality water gate design including design principals, material selection and manufacturing procedures.

ICS produced a comprehensive training manual and conducted a series of training sessions with Auke’s salesmen and engineers to train the staff on the fundamental and advanced aspects of canal modernisation. The sessions covered a range of topics from canal evaluation, gate selection, control system development and customisation, canal control algorithm specification and commissioning, SCADA development and cloud computing fundamentals. The comprehensive training sessions enabled the Auke staff to better understand theirclient"sneeds and to effectively turn those needs intohigh qualityproject solutions.

During the first 6 years, all the business I did was based in the United States. I did gates in California; Central Florida; Idaho; Port Arthur, Texas; and Utah. There’s one gate that we do, and that nobody else really got into, called the overshot gate.

Frank Stang: We just completed the largest single project that I’ve ever done in my 35 years in the business at Bassano Dam, which is one of the biggest reservoirs in southern Alberta for the storage of irrigation water. It is about 21⁄2 hours from our plant. We built 10 epoxy-coated gates, each 35 feet wide and 14 feet high, complete with electric cable-driven hoist systems, stainless-steel embedments, 10 emergency stop logs, and the lifting device. We just completed the installation of all these components. The owner, Eastern Irrigation District, commissioned them in April of this year. The total investment cost was in the $50 million range.

Trevor Hazell: The front skin plate was 3/8 plate—that’s probably the most significant measurement for a radial gate. There are also some really large I-beams that reinforce the back side of the gate, which is 18 inches deep. It involved a massive amount of steel.

Trevor Hazell: The radial gate itself was actually built in one piece. Two arms are bolted onto that, and those two arms are bolted onto the trunnion beams that are attached to the wall. Instream completed everything from the fabrication of the components to their installation, commissioning, and testing. I was on site as the supervisor for the installation of all 10 gates. From start to finish, each gate took 10 days, including all the bottom sills and side-rubbing plates that were embedded in the concrete structure, all the secondary concrete, and the lifting in of the gates, hoists, and hoist decks. It took us about 100 days in total.

Frank Stang: These gates are a part of the emergency spillway for the dam. About 5 years ago, there was a lot of rain and a lot of flooding. They just about lost this dam because they couldn’t spill enough water through the ordinary gates, of which there are about 25. After this emergency, Eastern Irrigation District, which is one of the biggest irrigation districts in this area, along with the Alberta-based irrigation consultant MPE Engineering, decided that it needed to incorporate another structure. The district built this emergency spillway for that reason.

Kris Polly: I understand that you’ve done a lot of work on similar gates for the U.S. Bureau of Reclamation and the Army Corps of Engineers in the United States. Is that correct?

The two types of adjustable sluice gate, undershot and overshot, are widely used for the control of water in canal systems. In the absence of more accurate devices they may be used for the approximation of flow rates.Sluice gates are made from stainless steel and plastic and are designed to fit in a rectangular section channel 450mm wide.

Automatic control gates are used extensively in canal systems for regulating water levels and discharge. They are usually float operated and are designed to maintain constant levels in the canal so that discharges from off takes can be kept at a constant known rate.

This is a counterbalanced radial-type gate which is controlled by means of a displacer located in a chamber. The displacer chamber is fed with upstream water via a vee notch weir and water is discharged from the chamber downstream through a circular orifice. The flow through this orifice may be adjusted by means of a throttle valve, altering the characteristics of the gate as required. The gate, of the undershot type, provides upstream level control and is designed to fit in a rectangular channel section 450mm wide.

This consists of a gate flap which is hinged at the base, The position of the gate is controlled by means of a displacer housed in a chamber. Water is fed to the chamber from the upstream side over a vee notch weir and discharged downstream through an orifice. A throttle valve allows the orifice flow to be controlled and the gate characteristics to be modified as required. The gate, of the overshot type, provides a further method of control of upstream level and is designed to fit in a rectangular channel section 450mm wide. This is a radial-type gate incorporating bouyancy tanks.

This is a radial-type gate incorporating bouyancy tanks. The gate floats at a constant depth so the head of water over the gate crest therefore the flow, remains constant despite variations in upstream level. The gate is suitable for applications where constant flow is required, for example in irrigation canal off takes and is designed to fit in a rectangular channel section 450 mm wide
