    Optimal Allocation of Water Resources Based on GWAS Model in Handan,China by LIU Guanghui, SUN Jianwei, LUO Yun, ZHAO Xian, REN Shuai, LIU Ruiting, WANG Jixuan

    Published 2024-01-01
    “…In recent years,the inflow of upstream rivers in Handan City has decreased,and the total amount of groundwater exploitation has become more limited,which fails to meet the rising water demand of different industries.In addition,due to the replacement of water supply sources for some industries after the construction of the South-to-North Water Diversion Project,the Yellow River Diversion Project,and the Yinwei River Water Diversion Project,the shortage and the contradiction between supply and demand of water resources in Handan City are becoming acute and complex.By analyzing the characteristics of water resources and the distribution characteristics of water conservancy projects in Handan City,the water supply and demand of each district and county in Handan City are predicted,and a multi-source,multi-user,and multi-objective optimal allocation model of water resources in Handan City is constructed based on GWAS.The results show that the total water demand in Handan City with a guarantee rate of P=50% in 2025 is 3 013.01×10<sup>6</sup> m<sup>3</sup>;the total water allocation is 2 473.97×10<sup>6</sup> m<sup>3</sup>,and the water shortage rate is 17.89%.The total water demand with a guarantee rate of P=75% is 3 434.90×10<sup>6</sup> m<sup>3</sup>;the total water distribution is 2 498.22×10<sup>6</sup> m<sup>3</sup>,and the water shortage rate is 27.27%.The water shortage is mainly concentrated in the primary industry.The allocation results are in line with the actual water consumption situation in Handan City,and the research results can provide a technical reference for water resources management in Handan City.…”

    Study on Anisotropic Petrophysical Modeling of Shale: A Case Study of Shale Oil in Qingshankou Formation in Sanzhao Sag, Songliao Basin, China by Ang Li, Liyan Zhang, Jianguo Yang, Shichao Li, Fei Xiao, Yulai Yao, Yiming Huang, Bo Liu, Longsheng Li

    Published 2023-01-01
    “…Based on the petrological and microstructure characteristics of shale in the Qingshankou formation of Sanzhao sag in the north of Songliao Basin, this paper presents an anisotropy petrophysical model with complex pore structure suitable for organic shale constructed with the use of the Voigt-Reuss-Hill average model, an anisotropy self-consistent approximation+differential effective medium model, and the layering of clay and kerogen is simulated by using the Voigt-Reuss-Hill average and bond transform to achieve the simulation of shale anisotropy. …”

    A Hybrid Short-Term Traffic Flow Multistep Prediction Method Based on Variational Mode Decomposition and Long Short-Term Memory Model by Qichun Bing, Fuxin Shen, Xiufeng Chen, Weijian Zhang, Yanran Hu, Dayi Qu

    Published 2021-01-01
    “…The prediction performance of the proposed hybrid model is investigated using inductive loop data measured from the north-south viaduct expressway in Shanghai. The experiment results show that (1) VMD algorithm could effectively avoid the problems of endpoint effects and modal aliasing, and the decomposition effect is better than empirical mode decomposition algorithm and wavelet decomposition algorithm; (2) among all the involved methods, the proposed hybrid model is more effective and robust in extracting the trend information, which has the best multistep prediction performance.…”
