The author together with Bochkarev V developed a hydraulic automatic water level controller with flexible working bodies. To determine the throughput and determine the optimal profile shape of the weir of its shutter, experimental studies were conducted. They were carried out by the method of physical modeling of the model and nature in an experimental setup, with the study of three types of shutter models with flexible working bodies with the shapes of a part of the spillway in the form of a board, non-vacuum and elliptical vacuum profile. Based on the results of these studies, without and with a side stream, formulas and dependency curves are obtained for determining the flow rates of the spillway with three forms of its part of the spillway. An analysis of the results of the study showed that the shutter with the spillway non-vacuum profile without has a slightly lower throughput than others, but is characterized by stable operation without vibration and is therefore recommended for use.

To eliminate the shortcomings of the known hydraulic autoregulators of the water level, together with Ya. V. Bochkarev, we developed a design of a hydraulic autoregulator of the level with flexible working bodies, combined with an automatic gate for washing sediments, which provides the discharge of floating bodies and bottom sediments in front of the partition structure. To ensure stable vibration-free operation of this hydro-automatic level controller, the task was set to justify the shape and size of the elements of its main gate and the gate-automatic washing of deposits and determine the throughput of the automatic gate washing of deposits. As a result of solving this problem, for the stable vibration-free operation of the hydro-automatic level controller, a non-vacuum shape of the profile of the spillway part of its main gate was adopted, the shapes and sizes of other gate elements were justified, and a theoretical formula for the throughput of the automatic gate for washing sediments was obtained, taking into account the lateral outflows.

To determine the throughput of the automatic gate of the flushing device, which is part of the hydraulic automatic water level controller with flexible working bodies, developed by the author together with Ya.V. Bochkarev, experimental studies were conducted. They were carried out by the method of physical modeling of the model and nature on an experimental installation, with the installation of two models of an automatic shutter: a) with a fixed angle of inclination of the pressure board, b) with an automatic shutter in the form of a container consisting of a rigid board under pressure in front of it and a rubberized fabric, as part of an automatic water level regulator. Based on the results of these studies, formulas and dependencies were obtained to determine the flow rates without taking into account and taking into account the lateral outflows and lateral compression coefficients and the water flows passing through the automatic gate.
