Dam Shutters

The dams are provided with vertical or circular gates to release the extra water that could be accumulated. The gates are designed to release maximum discharge to safeguard the dams. If the gates/shutters are not opened, after maximum storage is reached, water overflows from dam proper, earthen flanks/saddle dams/ earthen embankments. Gradually these earthen dams breach and even the main dam portion may also get damaged. To avoid such worst situations, gates operation schedules are prepared well in advance and looking at the inflow and predicted rainfall, the dam gates are operated. This project is executed for Public Works Department in the year 2021 at Ramanathapuram.
