    A Copula-based Method for River Ecological Flow Quantification and Algal Bloom Risk Assessment in the Hanjiang River by NONG Xi-zhi, LAI Cheng, JING Zheng, YE Ye

    Published 2025-05-01
    “…The results from Copula functions were compared with those from the Tennant method and Hydrological Inflection-Point (HIP) analysis for validation. [Results] (1) The joint distribution model based on Gaussian Copula function passed the K-S test and effectively captured the significant negative dependence structure between flow and algal density.(2) During the 2018 algal bloom outbreak in Hanjiang River, when the flow exceeded 728.00 m3/s and 1 096.30 m3/s, there was over an 80% probability that algal density would exceed 2 561.10×104 cells/L and 902.93×104 cells/L, respectively. (3) The hydrological inflection point method calculated the initial flow of algal bloom with an error within 100 m3/s, demonstrating higher accuracy than the Tennant method. …”
