To research the environmental problems of estuaries and coastal seas, we must learn the tidal flow field in detail firstly.
所以在近海工程及环境问题的研究中，必须首先要对潮流场有一个详细的了解。
A 2-d tidal flow mathematical model of Xinghua Bay based on irregular triangular grid finite difference method was set up and numerical simulation of tidal flow field was carried out.
建立了基于不规则三角形网格有限差分法的兴化湾二维潮流数学模型，对兴化湾潮流场进行了数值模拟。
The calculation and its verification show that the calculated processes of tidal level and current fairly well coincide with field data, and the flow field of calculation is reasonable.
实例计算和验证表明：计算的潮位和潮流过程与实测过程吻合较好，计算的流场合理。
