    Study on Flood Simulation and Its Real-time Correction of Qinhuai River Basin Based on Grid-Xin'anjiang Model by SUN Wenyu, WANG Rong, YAO Cheng, HE Jian, LI Zhijia, GONG Junfu, HUANG Pengnian

    Published 2021-01-01
    “…There are many small and medium-sized rivers in China,with frequent floods and serious disasters,which are the key weak links in flood prevention and control.Qinhuai River system is one of the most important water bodies in Nanjing,and the possible flood disaster in the flood season poses a threat to the life and property safety in the whole city.Taking Qianhan Village in Qinhuai River basin as the research object,this paper conducts the flood simulation through the Xin'anjiang model and Grid-Xin'anjiang model,and corrects it in real time by the KNN method and feedback method,so as to realize fast and accurate flood forecasting calculation.The results show that without real-time correction,the simulation accuracy of the Grid-Xin'anjiang model is slightly better than that of the Xin'anjiang model,and the simulation results of the two models are generally good.After real-time correction,the simulation results of the Xin'anjiang model and the Grid-Xin'anjiang model are improved obviously,which can provide an important basis for the decision of flood control and disaster reduction in the Qinhuai River Basin.…”

    Analysis of Long-term Water Quality up to the Standard in Jinchuan River Basin Based on Hydrodynamic and Water Quality Model by CHEN Liming, YU Xin, JIN Zhe, CHEN Chen, CHEN Liangang, WANG Gaoxu

    Published 2023-01-01
    “…The water quality of the Jinchuan River Basin cannot reach the standard steadily all year round.Thus,after analyzing the pollution characteristics of the basin,this paper proposes three schemes for water quality that can reach the standard in the long term,considering the improvement in the treatment,water supplement,and sewage interception abilities in sewage treatment plans of this basin.Meanwhile,prediction and analysis are also conducted on the water quality improvement effects of each plan.The results are as follows.In current pollution source conditions,regarding the two schemes where sewage treatment efficiency is increased by 10% and the basin water supplement rises by 50% on this basis,the peak concentration of ammonia nitrogen decreases,whereas the concentration is still higher than the Class V water standard.In the third scheme where the inflow concentration can achieve the assessment objectives of a south sewage treatment plant,the pollution load of pollutants into the river is reduced by about 44.4%.Therefore,the ammonia nitrogen concentration in the river network is significantly decreased,and the ammonia nitrogen concentration in the Baotaqiao section of downstream is reduced to 1.85 mg/L.Its water quality can meet the long-term water quality up to the standard in the whole process.The results can provide an effective scientific basis for water pollution control and prevention in the Jinchuan River Basin.…”
