The research advances of fundamental theory and typical problems of engineering hydraulics,environmental hydraulics and riverside urban hydraulics about the Yellow River were summarized by this paper. On fundamental theory of hydraulics,the researches about the correction method of weir and sluice＇s flood discharging capacity for distorted physical model,the discharge coefficient of water release structure with hyper-concentrated flows and the similarity rate and simulation method of ice flow＇s impact force in the hydraulic model were stated. On engineering hydraulics,the problems of representative new orifice energy dissipator of Xiaolangdi and multiple-segment composite guide wall form and high submerged spillway tunnel of Xixiayuan Hydraulic Project were demonstrated. On environmental hydraulics,the research advances of adsorption capacity from suspended sediment to phosphorus and sediment ＇s group settling velocity laws affected by phosphorus under the hydrodynamic environment were included. On urban hydraulics,the studies of urban pipeline clogging mechanism in Zhengzhou and drainage capacity of Yunliang River system in Zhengdong New District were illustrated.
