    METHODOLOGY FOR TAKING INTO ACCOUNT THE MORPHOLOGICAL FEATURES OF RIVER CHANNELS AND DANKFULL DISCHARGES HEN ESTABLISHING THE PLANNED POSITION OF THE WATERCOURSE COASTLINES by Viktor M. Katolikov, Nataliya I. Katolikova, Vladimir Y. Georgiyevskiy

    Published 2021-04-01
    “…Based on the analysis of a large volume of data of hydrological regime observations, as well as of field hydro/morphological studies, it is shown that, due to the ambiguity of the definitions of certain provisions of the Water Code of the Russian Federation, related to the establishment of the planned position of the coastline (boundary) of the watercourse, in some cases the implementation of these provisions is practically impracticable. …”

    Study of Bed Deformation Trend of Wakouzi-Majiazui Section in the Upper Jingjiang Reach of Yangtze River by ZHANG Hong, LIU Qihang

    Published 2021-01-01
    “…The riverbed scour and deposition of sandy section in Jingjiang reach of Yangtze River deforms dramatically since the operation of the Three Georges Reservoir.Taking the Wakouzi-Majiazui section as the example,based on recent channel topography and hydrological data,this paper simulates and predicts the bed deformation trend of the section for the next 20 years through a two-dimensional flow-sediment numerical model.The results indicate that:The river regime of Wakouzi-Majiazui section is generally stable for the next 20 years,and the main channel erosion will continue and develop downstream.The Jincheng sandbar shows no significantly variation,and the evolution of Tuqi sandbar is characterized by the sedimentation of left branch and scouring of right branch,with the right branch in dominant position continuously,which offer an important reference for channel and waterway regulation.…”

    Analysis of Reservoir Regulation Capacity Based on Cascade POA Optimal Scheduling Model by HOU Jiaqi, CHEN Cong, TIAN Yuanyang, XIONG Yicheng

    Published 2021-01-01
    “…Due to the completion of the cascade reservoirs,the hydrological process of the basin has changed significantly,and the scheduling of the existing reservoirs has changed.The assessment of the regulation capacity of the existing reservoirs will help to re-define the role of the reservoirs in the runoff regulation.Taking Menkantan hydropower station and Datankou reservoir on Modaoxi Basin as examples,this paper proposes the concept of “virtual regulating storage”,and constructs a cascade POA optimal scheduling model to verify the regulation capacity of small hydropower stations.According to the calculated results,the amount of discarded water is reduced compared to that in the original operation mode,and the downstream reservoir's ability to regulate incoming water is effectively improved.The research results provide a reference for the verification of reservoir regulation capacity,and a mode to improve the power generation efficiency of small hydropower stations.…”
