    Deep characteristic learning model for real-time flow monitoring based on H-ADCP by Yu Li, Xin Zhao, Yibo Wang, Ling Zeng

    Published 2025-02-01
    “…Study focus: Real-time flow monitoring based on horizontal-acoustic Doppler current profiler (H-ADCP), which remains insufficient to deal with low monitoring accuracy, complex flow characteristics, and large data volumes caused by the construction and operation of hydraulic engineering, backwater, tides, siltation changes, and high-frequency monitoring. This study proposed a deep characteristic learning (DCL) model to identify and extract the nonlinear characteristics between flow velocity of H-ADCP cell and river cross section by incorporating multiple intelligent algorithms. …”

    Modelling of Chain Process of Debris Flow Blocking River and Induced Flood Disaster in Meizoseismal Area ——A Case of Xiazhuang Gully in Wenchuan County by LUO Yuting, WANG Lijuan, MA Song, TANG Yao

    Published 2023-01-01
    “…After the Wenchuan earthquake,there has been a sharp increase in the frequency of debris flow activity,which is featured by low rainfall threshold,frequent occurrence,wide impact and strong destruction.The hazards mainly include siltation,impact,river blocking and inundation.Among them,the mudslide blocking river shows particularly prominent disaster effect,seriously threatening the improvement of mountain infrastructure,and residents' life and property safety.The research of the dynamic process of river blocking disaster chain of debris flow can provide scientific reference for debris flow hazard prevention and early warning.Based on field surveys,physical tests,remote sensing images and rainfall data for a typical watershed,a numerical simulation was conducted to study the dynamic process of the river blocking disaster chain of debris flow in Xiazhuang Gully.The simulation results show that the debris flow reaches the outlet of the basin at t=120 step;and at t=130 step the debris flow pushes forward and blocks part of the main river;at t=140 and 150 step the debris flow completely blocks the main river,forming a debris-dam with a length,width and thickness of 236.0 m,74.0 m,6.2 m and 312.0 m,79.0 m,and 7.1 m,respectively,which causes the upstream water level to rise,with an inundation depth of the upstream residential area of 3-5 m.By comparing the simulation results with the field measured data,the accuracy of the simulation reaches up to 84.9%,which indicates that the model is of good applicability to simulating the disaster chain process of landslide-debris flow-flood.…”

    Experimental Study on Dewatering of Hydraulic Silts by Horizontal Electroosmosis Combined with Surcharge Preloading by YANG Yang, CHEN Renyuan, QIU Zhenfeng, WU Liqing

    Published 2021-01-01
    “…A large amount of dredging silt will be produced in the urban water environment treatment project.With high water content and large volume,the silt will occupy a lot of land resources after being dumped in the storage yard directly.This paper designs a model test for the treatment of hydraulic silts by the horizontal electroosmosis method,performs the dewatering of hydraulic silts through the horizontal electroosmosis combined with surcharge preloading,verifies the feasibility and advantages of horizontal electroosmosis for silt dewatering.The test results show that:The upper load can limit the crack width of silt.The larger the upper load is,the smaller the crack width of silt is,the bigger the silt settlement is,the larger the silt displacement is,and the lower the moisture content is.The upper load can delay the attenuation of electric flow and the reduction of the effective electric potential,which is conducive to the dewatering and consolidation of silt.At the final stage of electroosmosis,the energy consumption is high and the dewatering is small.Therefore,in practical application,electroosmosis should be stopped before this stage.…”
