Abstract
The operation of hydraulic structures needs the presence of a number of specialists to make decisions to instantaneous takes actions at an appropriate time through controlling, monitoring, and giving a suitable warning for any undesirable cases like increasing water level higher than the normal level, stopping of any device. One of the monitoring tool is SCADA system which can allow the water manager to continuously compare the actual hydraulic state of the system with its optimal hydraulic state, and to take appropriate corrective steps as required .The proper application of the system in irrigation districts, can lead to improved water delivery service to farm, more effective operations, and in some cases a reduction in costs (less labor, less energy). In order to demonstrate the suitability of monitoring system such as the SCADA system, it was applied at Shatt Al-Hilla situates in Hilla city, 100 Km south of Baghdad city in Iraq. It is the main channel that is branched from the left side of Euphrates River, just upstream the Hindiya Barrage. The system was applied at a33 Km reach from station (0+000) to station (33+000) and simulating the controlling of the head regulator at station (0+000). SCADA system components consisted of a computer server as a master station, interface field data devices usually RTUs, or PLCs to allow interface between field sensing devices and local control switchboxes and gate actuators, communication system to transfer collected data and appropriate standards and or custom software. The hardware architecture of SCADA system was established for this reach and the controlling of the head regulator of Shatt Al-Hilla at sta. (0+000) is simulated. The head regulator of Shatt Al-Hillawas run for three cases with six scenarios. The first case is for the daily discharges supplied to the head regulator for the year 2011, the second case is for the monthly water demanded to the head regulator (2011), and the third case is for the daily discharges that can be supplied to the head regulator for 2012 summer season .All cases and scenarios simulation produced good results except scenario (6) for the three cases because there are deficits in supplying the discharges in many days through the year, Also for case (2) there are deficits of 1.57%, 16.67%, 18.46%, and 14.04% of the total demanded discharges for Mar., Apr., June, and July respectively.
