River training for flood protection (also known as 'high water training' or 'training for discharge') [...]
Most commonly used methods for stream gauging are: 1. Area-Velocity Method 2. Area Slope Method 3. Discharge Measuring Structures. 1. Area-Velocity Method: It should be noted that depth of flow varies in a section of a stream across the main flow direction. Likewise, the velocity of flow too varies from point to point within a cross-sectional area of the stream. [...]
This article throws light upon the four regulating devices generally used for controlling water reservoirs. The regulating devices are: 1. Flashboards and Stop-Logs 2. Vertical Lift Gates 3. Radial Gates 4. Drum Gates. 1. Flashboards and Stop Logs: Flashboards and stop logs raise the reservoir storage level above a fixed spillway crest level when the spillway is not required to [...]
