Abstract: Disclosed is a method for determining a sediment regulation scheme of a cascade reservoir under water storage/discharge conditions, which includes: acquiring basic information and measured information of each associated reservoir in a target cascade reservoir system; where the target cascade reservoir system is a cascade reservoir system requiring sediment regulation, and the target cascade reservoir system includes at least two target reservoirs cascaded along an associated river system; predicting, based on the preset water storage/discharge sequence scheduling mode, the basic information and the measured information, a cumulative siltation amount and a regulated siltation amount within reservoir capacity of the target cascade reservoir system within a future preset time period by utilizing a preset reservoir sediment scouring and silting calculation model; and determining, based on the cumulative siltation amount and the regulated siltation amount within reservoir capacity, a target water storage/discharge

Abstract: A method and device for optimizing regulation of reservoir sediment discharging, comprises: determining a relation curve between a dam front water depth and a reservoir capacity; determining a time length by which a sediment peak is propagated to the front of a dam and a time length by which the sediment peak lags behind a flood peak at the front of the dam based on the relation curve and the hydrologic features; determining another relation curve between a sediment peak attenuation rate and a sediment concentration of the sediment peak, and a time length by which the sediment peak subjected to a man-made flood wave is propagated to the front of the dam; and acquiring a real-time sediment concentration, and generating the man-made flood wave based on the time length by which the sediment peak is propagated to the front of the dam and the another relation curve.

Abstract: An 8-dihalomethyl berberine-type quaternary ammonium salt compound represented by general formula (I) or (II) and an application thereof in preparing a drug. The compound shows hydrophilicity and has antimicrobial, anti-inflammatory, anti-ulcerative colitis, and antitumor activities, while having no or low toxicity.

Abstract: Provided is a lateral water intake structure for preventing silting of bed load and floating debris, which is provided at a river bank. The lateral water intake structure includes: a diversion canal, a guiding wall structure, a shaft-shaped water intaking space, and a trash rack. The lateral water intake structure functions to prevent the floating debris from gathering at the surface of the trash rack and reduce a risk that the trash rack is damaged by water pressure and hitting of the floating debris. Meanwhile, by using a water flow in the watercourse to continuously wash the floating debris near the trash rack, maintenance costs of removing the floating debris at the trash rack manually or mechanically can be reduced.
