潮汐通道 meaning in English

tidal intel

But , in some other water areas such as the narrow - deep tide channel , narrow - deep valley reservoir and narrow - deep estuary area , the vertical varies of parameters such as the velocity , temperature and concentration is far greater than that in the horizontal direction , so the two - dimension vertical numerical simulation technique should be adopted in these areas
而在另外一些水域，如窄深潮汐通道、窄深型河谷水库如三峡、窄深河口地区，有关参量(如流速、温度、浓度等)的垂向变化要比水平横向的变化为大，应采用垂向二维水流水质数值模拟技术。
