I. Astronomical factors of tides
The cham tong river is formed mainly by the sun, the moon and the earth's gravity, as well as by the spread and overlap of tidal waves. The gravity of the sun and the moon has caused the sea to rise and fall up and down in the coastal zone, forming tides, which are larger than the tides of the sun and can reach a few metres apart, which is one of the reasons for the currents of the chandong river。
Ii. The estuary terrain
Another factor affecting the chai tong river is the estuary terrain. The topography of the estuaries affects tidal changes, such as the size, depth and degree of twist of the estuaries. The narrowness of the estuary will affect the change of tides, which will become larger if the estuaries are narrower, and smaller if the estuaries are wider。
Iii. Deep in the estuary
Deep estuary waters are also important factors affecting the chandong river tide, which, if deeper, becomes larger and, in turn, smaller。
Iv. Water temperature in the estuary
The estuary water temperature is also an important factor affecting the chai tong river. The higher the temperature, the greater the tide, the lower the temperature, the smaller the tide。
V. The effect of tides on the chandong river basin
Changes in the chandong river can have important implications for the chandong river basin, for example, changes in the tide can affect river flows, changes in river beds and sedimentation of estuaries. Tidal changes also affect navigation and fishing activities in coastal areas, thereby affecting their economic development。
Vi. Interesting contexts
The change in the chandong river is also a landscape, and the change in the tide every year is also the focus of attention. Every year, a large number of tourists travel to the chandong river to observe the tide and to enjoy the natural beauty of the river, which is also an interesting part of it。
