What is a dammed river and what is a dammed lake?

Wudalianchi volcanic group is a famous modern volcanic group in China, they are formed by intermittent eruption in the Quaternary Period, the volcanic lava area reaches more than 80 kilometers, among which the old black mountain and the fire mountain erupted in 1719-1721, it is the latest volcano in China, retains the traces of various lava flows, and forms five lakes by the lava dam river, Wudalianchi gets its name from this.

The original name of Xiaonanhai"Small win sea"It is a dammed river formed by a level 5** that occurred in the 6th year of Xianfeng in the Qing Dynasty (1856 AD), causing a large mountain to collapse and block the river.

Jingpo Lake was formed in the Cretaceous period on the basis of a faulted lake basin and a volcanic lava dam on the riverbed. Wudalianchi is the largest volcanic landform landscape in China.

Once the landslide group becomes a disaster, it will also block the river at the front edge of the mountain, and it is easy to form a dammed river, and the embankment of this river is very soft, which is particularly easy to cause debris flow, which poses a serious threat to the life and property safety of 6,000 people on both sides of the river at the front edge of the landslide and downstream.

** Or volcanic eruptions cause landslides or collapses, or magma flows out to block the original river channel to form a dammed river or dammed lake, this kind of river or lake is unstable, and the flood accumulation is serious, which may cause the "dam" to collapse and form a flood.

In 1933, the dam collapse of the dammed river in Sichuan caused a flood that killed 20,000 people, and the dam itself was only 500 people, which shows that the harm of the dammed river (lake) is very serious.

** After causing landslides or collapses or magma outflows, blocking the original river channel to form a dammed river or dammed lake, this river or lake is unstable, and the flood accumulation is serious, causing the "dam" to collapse and form a flood.

A dammed lake is a lake formed by blocking a river valley or riverbed after a landslide caused by a volcanic lava flow or a landslide caused by ** activity. Lakes formed by the interception of volcanic lava flows are also known as lava dam lakes.

There are four processes in the formation of a dammed lake: first, the original water system; Second, the original water system is blocked by blockages. Third, after the river valley and riverbed are blocked, the flowing water gathers and overflows in all directions. Fourth, when the water is stored to a certain extent, a dammed lake is formed.

Once the dammed lake bursts, it will form a flood peak downstream, and if it is not properly disposed of, it will cause major disasters.
