    Reliability Analysis of Water Intake Based on MIKE Model by LIANG Zhihong, ZHENG Jiangli, CHEN Xiuhong, LIU Xia

    Published 2021-01-01
    “…The reliability of water intake is one of the main factors affecting the operation of the project,and is a prerequisite for the project to be put into use.Taking the 10 million-ton-level metallurgical new material industrial base in Wuzhou as the research object,based on the MIKE21 module in the MIKE software,this paper establishes a hydrodynamic model for verifying the reliability of the existing water intake scheme,as well as puts forward the corresponding countermeasures for the scheme with water intake risk.The results show that:①During the dry season,the water level of the Changzhou Water Control Project is relatively high,and the reservoir storage can meet the design water intake quantity of the project;②During the normal water period,the gates of Changzhou Water Control Project need to be opened to ensure the safety of flood control.If the inflow of the Shangxiaohe tributary of Xunjiang River is abundant,the project is guaranteed with water intake.If the inflow of the Shangxiaohe tributary is small,the project will have water intake risk;③Countermeasures such as dredging the river channel and lowering the water intake can effectively increase the water intake of the project,thereby avoiding the water intake risk of the project during the normal water period.The research results are of guiding significance for the construction of the 10 million-ton-level metallurgical new material industrial base in Wuzhou,and of theoretical significance for water intake reliability analysis through MIKE21.…”

    Study on the Dispatching of Key Reservoirs in the Xijiang River Basin for Saltwater Resistance and Freshwater Supplement by LIU Xia, BAI Tao, WU Yunchen, HUANG Qiang

    Published 2020-01-01
    “…Taking the eight key reservoirs in the Xijiang River Basin as theresearch object, this paper formulates the real-time dispatching simulation schemes of singlereservoir, two reservoirs and eight reservoirs in dry season respectively, and aiming at the low-water conditions of 95% and 99% incoming water frequency, establishes and applies the real-timedispatching simulation model of key reservoirs in the Xijiang River Basin to meet the saltwaterresistance and freshwater supplement demand of Wuzhou section at the downstream of Xijiang RiverBasin. …”

    Research on Medium and Long-Term Runoff Forecast of Xijiang River in Dry Season Based on Statistical Model by LAN Yuxi, ZHANG Yin, NONG Zhenchang, WEI Yongjiang

    Published 2022-01-01
    “…Accurate medium and long-term runoff forecast is of great guiding significance to the development and utilization of water resources,allocation optimization,and water dispatch.Based on the three statistical models of mean generating function,periodic analysis,and multiple stepwise regression,this paper studied the medium and long-term runoff forecast of the Longtan Reservoir in the upper reaches of the Xijiang River and the Wuzhou hydrological station in the lower reaches from October to March of the following year and during the entire dry season (six months,from October to March of the following year).The results show that the three models all present positive forecast results.In the calibration and verification periods,the average pass rate exceeds 75%,and the mean absolute percentage error is basically within 30%.The forecast accuracy of the mean generating function and the multiple stepwise regression is significantly higher than that of the periodic analysis,with smaller forecast errors in larger values.Multiple stepwise regression is more stable than the other two models.Furthermore,affected by the consistency of data,the forecast accuracy of the Longtan Reservoir is significantly higher than that of the Wuzhou hydrological station.On the whole,multiple stepwise regression has the optimal forecast effect in the Xijiang River Basin.In addition,it can maintain high forecast accuracy at all levels and stages and provide a valuable reference for water dispatch decisions in the basin.In the future,multi-model fusion can be used to further improve the forecast effect.…”

    Application of a DEM-based Distributed Rainfall-Runoff Model Considering Karst Landform in the Xijiang River Basin by CHEN Shilei, XIONG Lihua, ZHA Xini, SHU Peng

    Published 2020-01-01
    “…Based on the hydrologicalcharacteristics and variability of karst landform, this paper improves a DEM-based distributedrainfall-runoff model (DDRM) for karst basins by considering the effects of epi-karst zone on waterstorage capacity and underground river system on runoff yield, and applies both the original andimproved DDRM in the Xijiang River Basin to simulate the daily runoff at the Wuzhou Station duringthe period of 2010 to 2016. The comparison of the simulation results of the two DDRM models showesthat the improved DDRM model remarkably enhances the simulation accuracy of the daily runoff andhas better simulation performance in both flood season and dry season for karst basin.…”
