一、引言 渤海是我国重点保护水系之一。为了控制水域污染,制定废水排海标准,首要步骤须查明入海污染物质的扩散过程。在渤海,潮流是形成污染扩散的主要营力之一,为此首先计算渤海的潮流及潮余流场。 近二十年来,随着电子计算机的迅速发展和计算技术的进步,潮汐动力学进入了数值研究的新阶段。这一新方向的特点,是以求解自然条件下长波方程的初值——边值问题为出发点,研究以往所不能解决的许多复杂现象。
I. Introduction Bohai Sea is one of the key protected water systems in China. In order to control the pollution of the water area and formulate the standard for wastewater discharge, the first step must be to identify the diffusion process of pollutants into the sea. In the Bohai Sea, the tide is one of the major camping forces that form the basis for the spread of pollution. To do this, we first calculate the tidal current and the tidal current over the Bohai Sea. In recent two decades, with the rapid development of electronic computers and advances in computing technology, tidal dynamics have entered a new phase of numerical research. The new direction is characterized by the solution of the initial value-boundary value problem of long wave equations under natural conditions and the study of many complicated phenomena that can not be solved in the past.
