Application of Harris Hawks Optimization Algorithm in Optimization of Generalized Nonlinear Muskingum Parameters ——A Case Study of the Luohe River
Published 2024-01-01“…The Muskingum model plays an important role in river flood simulation,and its simulation accuracy relies on the optimal selection of parameters.To address the current challenges in parameter calibration for the Muskingum model,such as complex solution processes and low accuracy,the use of the Harris Hawks optimization (HHO) algorithm was proposed to optimize its parameters.HHO algorithm has a wide range of global search capabilities,with fewer parameters to be adjusted.Taking Luohe River,a tributary of the Yellow River,as the research object,the generalized nonlinear Muskingum model was used to simulate the flood in the Yiyang-Baimasi section of the river.The parameters were optimized by employing the HHO algorithm,particle swarm optimization (PSO) algorithm,and ant colony optimization (ACO) algorithm,respectively.The results show that the generalized nonlinear Muskingum model based on the HHO algorithm achieved high simulation accuracy in the Yiyang-Baimasi section of the Luohe River,with a Min.SSD of 1 237 and the flood peak error (DPO) of only 5,outperforming those obtained through optimization using PSO algorithm and ACO algorithm.The results are suitable for application in flood forecasting in the Yiyang-Baimasi section of the Luohe River.…”

Spatial Difference Analysis of Water Resources Carrying Capacity in Henan Province
Published 2022-01-01“…Taking 18 cities in Henan Province as the research objects,this paper selects 16 indicators from the water resources-society-economy-ecology composite system.Utilizing the entropy weight TOPSIS method,it conducts the spatial difference analysis and comprehensive evaluation of water resources carrying capacity on 18 cities in Henan Province in 2018.The evaluation results show that the water resources carrying capacity of Henan Province in 2018 is weak.From the perspective of spatial difference,the water resources carrying capacity is the strongest in the southern region,followed by the western region,and the northern and eastern regions are the weakest.Cities with descending water resources carrying capacity are as follows: Xinyang, Zhumadian, Nanyang, Zhengzhou, Sanmenxia, Luoyang, Pingdingshan, Shangqiu, Luohe, Jiyuan, Xuchang, Zhoukou, Anyang, Kaifeng,Hebi,Xinxiang,Jiaozuo,Puyang.The water resources subsystem and the economic subsystem have great influences on water resources carrying capacity in different cities.GDP,water production modulus,and precipitation affect the water resources carrying capacity most in 2018.…”
