Methods for Steam Gauging | Hydrology
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. [...]
