How deep is the water in the Yangtze River?

The water depth of the Yangtze River varies, generally only refers to the water depth of the main channel. Refer to the following table:

Yibin - Lanjiatuo 1.8 meters

Lanjiatuo - Louxigou 2.5 meters

Louxigou - Yangjiaotan 2.7 meters

Yangjiaotan - Baiwei 2.9 meters

Baiwei - Wuqiao 3.2 meters< /p>

Wuqiao - 4.0 meters at the mouth of the Wanhe River

4.5 meters at the mouth of the Wanhe River - Yanziji

Yanziji - 10.5 meters at the Longzhao Rock

< p> The navigation capacity of the Yangtze River first depends on the channel water depth. From the barrier sand at the Yangtze River Estuary to the navigation channels in the middle and upper reaches, all must be improved. The natural water depth of the Yangtze River Estuary is only 6 meters. After the 1970s, it was maintained at 7 meters by artificial adjustments. In 1998 After the first phase of renovation, the water depth reached 8.5 meters. After the completion of the second phase of the project in 2004, the water depth only reached 10 meters. The water depth of the Wuhu River Channel did not reach 6.5 meters until 2005 from 4.5 meters. According to the national "Ten Measures" In the 1st Five-Year Plan, the Ministry of Transport formulated the "Yangtze River Trunk Channel Development Plan." According to this plan, the country will invest more than 16 billion yuan to improve the Yangtze River Channel during the 11th Five-Year Plan. By 2010, the throughput capacity of the Yangtze River Mainstream will reach the following standards :

Nanjing Port and below can navigate 25,000-ton sea-going vessels all year round and a 20,000-40,000-ton fleet consisting of 2,000-5,000-ton barges;

From Nanjing to The water depth in Anqing reaches 6 meters, and it can navigate 5,000-10,000-ton sea vessels or 20,000-40,000-ton fleets composed of 2,000-ton barges;

The water depth from Anqing to Wuhan reaches 4.5 meters. The navigation period of 5,000-ton sea-going ships can be significantly extended;

The water depth from Wuhan to Chenglingji reaches 3.7 meters, and 10,000-ton oil tankers composed of 3,500-ton oil barges can be navigable. The water depth from Chongqing to Yibin reaches 2.7 meters, and 1,000-ton ships can be navigable by utilizing the natural water depth.
