Description
/ / / X Изобретение относитс к гидротехнике и мелиорации, в частности к способам измерени расхода воды. Цель изобретени - повышение точности измерени расхода воды. На чертеже схематически изображено гидротехническое сооружение, выполненное по типу водослива с широким порогом. Способ измерени расхода воды осуш ,ествл етс следующим образом. Две водомерные рейки устанавливают в верхнем бьефе 1, располага на рассто нии (4-5) Но от входа на водослив, и в нижнем бьефе 2 в створе схода воды с порога водослива 3. По рейкам фиксируютс уровни воды, а затем определ ютс глубины соответственно Но и hex. Величину расхода воды определ ют по формуле/// X The invention relates to hydraulic engineering and amelioration, in particular to methods for measuring water flow. The purpose of the invention is to improve the accuracy of measurement of water flow. The drawing shows schematically a hydraulic structure made according to the type of weir with a wide threshold. The method for measuring the flow of water is dried as follows. Two water gauges are installed in the upstream 1, located at a distance of (4-5) But from the entrance to the weir, and in the downstream 2 in the alignment of water from the weir threshold 3. The racks fix the water levels and then determine the depths respectively But also hex. The amount of water flow is determined by the formula

где b - ширина водосливного отверсти ; Но - глубина воды в верхнем бьефе перед сооружением;where b is the width of the water outlet; But - the depth of water in the upstream before the construction;
hex -глубина воды на сходе с водосливного порога; g-ускорение силы т жести.hex is the depth of water at the exit from the spillway; g-acceleration of body strength.
