The invention provides a sediment starting flow velocity measuring device. The sediment starting flow velocity measuring device comprises a sediment starting sensing component and a flow velocity vertical line distribution measuring component, a flow velocity measurement control circuit of the flow velocity vertical line distribution measurement part comprises an electromagnet control circuit and a flow velocity display circuit. The electromagnet control circuit comprises a water baffle, a spring coil and an iron core; the flow velocity display circuit comprises a permanent magnet, a spring, a slide rheostat and an ammeter. When the water baffle is impacted by water flow, after a spring coil is compressed, the number of electrified coils surrounding an iron core is increased, then the magnetic force of an electromagnet is increased, and a permanent magnet is pushed to compress a spring, so that the access resistance of a slide rheostat is reduced, and the current of a corresponding branch is increased; as the
