The invention discloses a measurement system and an observation method for the sediment transport rate at the bottom of the Yangtze River Estuary. The system includes a sand collection bucket, which is used to bury the bottom sand at the position of the observation point; Sand weight; dynamic balance module, used to keep the sand collection bucket in the set state; pressure gauge, used to obtain the water pressure in the sand collection bucket; waterproof collection module, used to collect the data of weight measuring instrument, dynamic balance module and pressure gauge ; Wireless transmission module, to send measurement data to the host computer; power supply module, to provide electrical energy to components; high-voltage waterproof box, to protect all electrical components from being damaged and wet by water pressure. The invention uses the combination of the sand collection bucket and the sand quilt skirt, combined with the weight measuring instrument, dynamic balance module, data acquisition instrument, wireless transmission module, and power supply module, to solve the problem of the poor measurement accuracy of the traditional sand delivery measurement system, which is greatly affected by the terrain and cannot The problem of real-time observation of sediment load is better applied to scientific research projects related to hydrological measurement.
Description
technical field [0001] The invention belongs to the technical field of on-site hydrological measurement, and in particular relates to a measurement system and an observation method for the sediment transport rate at the bottom of the Yangtze River Estuary. Background technique [0002] In the Yangtze River Estuary area, suspended sediment and bottom sediment are often referred to as sediment moving in the form of suspended matter and sediment moving in the form of drifting matter. Compared with the upstream rivers, the sediment particle size in the Yangtze Estuary area is relatively fine Most of the sediment can be lifted to become suspended sediment under certain water flow conditions. Suspended sediment transport is the decisive factor for the long-term evolution of the riverbed in the estuary. Affected by the tidal reciprocating flow, the exchange of suspended and transported mass in the estuary area is frequent. The Changjiang Estuary Bottom sediment movement generally r...
