ARMAC (Automatic Reservoir Monitoring And Control)

The "Automatic Reservoir Monitoring and Control System", called ARMAC for short, is a computerised control system for the monitoring and control of dam gates and reservoirs. Today, ARMAC is successfully applied in numerous dams all over the world.

The ARMAC system measures the water level of a dam every 15 minutes. The system takes into consideration the geographical contours of each reservoir, the so called area volume curves, as well as decades of historical river-flow data and the outfall water levels.
The real-time data are compared with the stored data and the current local requirements. This way the optimum opening of the spillway gates is calculated.
Rising and sinking water levels are measured by means of water level sensors installed in upstream and downstream positions. The ARMAC software allows the exact monitoring and adjustment of the water flows to maintain specified water levels.

Water level measurements are used by the system to calculate the inflows and outflows. The system then re-calculates the combined opening of the gates to control the outflow of water as required by the project, and commands the gates to open or close. The software helps to maintain the optimum reservoir level for the season by balancing the inflows and outflows.

The PC based system allows flexible programming and to change the response of the gates by changing the programme. The ARMAC system gives you a visual readout of the operational and the positional status of each gate at all times.
Continuous data on water inflows into reservoir discharge calculations, gate positions and hydraulic system performance are stored by the system every 15 minutes and can be used for future analysis.

The spillway gates are opened by retracting the cylinders. With cylinders fully closed, the gates are wide open. The outflow through the gate is controlled while monitoring inflows at the same time. Once the desired water levels are reached, if the inflows are reduced, the gates close through a reverse process.

Several dams along the same river system can be perfectly synchronised by using ARMAC.
The established data can be transmitted in real time via OFC/PLCC, VSAT or GPRS.

this is the best dam ever thats animated can you tell me what website you went to and do you have to buy this i love dams and i never could make one like you and i ben throw alot of anamted dams and this is the one gread dam

[MrTowess]

Why not use floaters to open the gate???

[abhishekpatra]

can i know the dams in the world which are controlled by armac??

[teoscott]

I would like to know which software has been used for the simulations done in this video. Thanks
