| titleOfInvention | METHOD FOR MEASURING SPEED OF A WATER FLOW ALONG A RIVER |
| abstract | 1. A method of measuring the speed of a watercourse along a river, including the use of a floating ruler with divisions, and during the measurements, the floating ruler is released along the course of the watercourse, characterized in that a section with hydrometric gauges is planned along the river, the average watercourse speed is measured in each hydrometric gauge, and the width of the river, its maximum depth and slope of the watercourse, after which statistical modeling reveals a three-factor regularity in the dynamics of the average speed of the watercourse along the river section. ! 2. The method of measuring the flow velocity along a river according to claim 1, characterized in that at least five hydrometric sections are planned on a selected section of the river. ! 3. The method for measuring the flow velocity along a river according to claim 1, characterized in that the average flow velocity is measured using floats of at least 10 measurements. ! 4. The method for measuring the speed of a watercourse along a river according to claim 1, characterized in that to increase the accuracy of the picture of changes in the speed of a watercourse along a section of a river, the measurement times of each value of the speed of a watercourse are synchronized in time, and for this, measurements are carried out simultaneously on all hydrometric sections of a river section. ! 5. The method of measuring the flow velocity along the river according to claim 1, characterized in that statistical modeling reveals a three-factor regularity in the dynamics of the average flow velocity along the river section using the formula:! ! ,,,! where ν is the average velocity of the watercourse in the gauge, m / s; ! νλ - regularity component showing the influence of the slope of the watercourse, m / s; ! νB is the relative component showing the influence of the width of the river on the change in the flow velocity along the river section |
