Device for measuring the speed of selective threshold bedload transport in the river bed

摘要

device for measuring selective speed threshold having a superstructure is characterized by the fact that it is composed of a hanging device on the bottom of the test system for the river, tunnel measurement (4), filter system and controls the work device. the deposition device at the bottom has supports (2) controlled actuators.in the tunnel measuring (4) is a sensor (18) speed of water. tunnel measurement (4) in the front part has a cover (6) and prostownicu0119 water jet (5). tunnel measurement (4) is connected through a three way valve (7) and conductors with at least one filter. speed flowing through the measuring tunnel (4) water is regulated by the control system (20).speed flowing through the measuring tunnel (4) water, during a single measurement cycle is constant.
