A 1-dimensional hydrodynamic model is developed for model establishment, rating, and verification of the scope from Huizhong of Dongjinag River to Dongjiang River Estuary, calculating and analyzing the influence of 6 regulation schemes to the water stage and flow speed of Boluo shallow reach under design minimum anvigation discharge, regulation discharge and all flood discharge, and determining the recommended scheme. The verification result shows that the model well simulates the real situation of the chan...
