Abstract:
Construction of hydraulic structures like barrage, dam, weir etc. across rivers for the purpose of flood control, irrigation, power generation, recreation etc. are very common. The gates are used in these hydraulic structures-to control and regulate the flow of water. They are also known as water regulating equipment.
Many type of gates are in successful operation. However, few of these may be suitable or economical for a specific situation. The tough job is to select and design the most appropriate type and size of gate, which will meet the hydraulic, operational, site condition and economic requirement:. The conditions like water head which could be low, medium or high, the lotations 'like spillway, barrage, intake, navigation channels etc., frequency and mode of operational requirement etc. are some of the basic considerations for the selection and successful installation of gates.
The failure of a gate may cause serious hazard and terrible situations, which may not only result in loss of life but may necessitate closing of project requiring high expenditure in rehabilitation and replacement of damaged gates. Therefore, the gates are the most important components on any water resources project. So, it needs specialization and expertise for selection, planning, designing, erection as well as maintenance....
