(1) Cyperus malaccensis is the indicator for tidal river freshwater species.

(2) The tidal river would push detritus into the most-used spots.

(3) By application to a certain tidal river showed that the computational method both in theory and practice were feasible.

(4) Current in tidal river shows a complex periodic characteristic, and it is unsteady flow moving alternately backward and forward.

(5) Use WASP5 to simulate the water quality of tidal river network controlled by gates. And optimize WASP5 model in accordance with the specific characteristics of tidal river network.

(6) Calculation of water environment capacity in the tidal river net controlled by gates is an important part of water environment management.

(7) At the estuary of tidal river, sedimentation occurs when sediments river by tidal flow.

(8) The serious non-point source pollution and cross-pollution in plain tidal river networks presented problems of environmental pollution and environmental safety.

(9) Introduces briefly the current situation of the research on the numerical simulation of water environmental capacity in tidal river and analyzes the main problems to be overcome.

(10) The paper has studied the characteristic and reason for flood in cities in tidal river area, and then has summed up the assignments faced with and existent problems in the area.

(11) The results show that the water quality at upstream and downstream in tidal river influences each other and the COD capacity of water environment is closely related to the fluctuation of tide.

(12) The achievements of this paper not only have provided gist for the flood prevention plan of NingBo City(Sentence dictionary), but also is applicable to other similar hydrological problems of cities in tidal river area.

(13) A depth-averaged two-dimensional unsteady flow with uniform non-equilibrium sediment transport model is proposed to simulate the riverbed deformation in a tidal river.

(14) EDSS is a comprehensive software system for water quality management in tidal river networks in general and for the Pearl River Delta in specific.

(15) A one-dimensional hydrodynamic and water quality model for river networks is developed, according to hydraulics and water quality features of water body within a tidal river network.

(16) Particularly, the solution for impermeable silt-layer can be used to describe the tidal fluctuation in a confined aquifer under a tidal river separated by an impermeable layer.

(17) The study of this paper is significant to solve the pollution in tidal river.

(18) Further, a coupling model of hydrodynamic model and water quality model was developed and it can be applied to simulate the water environment of a tidal river network controlled by gates.

(19) Bordered by tidal rocks on the left and a tidal river on the right, this cottage and its surrounding sandy beach are my sanctuary.
