Forum tackles a tidal problem

HOW to combat the salt tides at the mouth of the Yangtze River was one of the main items discussed at the Yangtze Forum in the city yesterday.

The Qingcaosha Reservoir which will be operational next year is expected to reduce the influence of the salt tides on the city, experts said.

It will ensure 68 days of fresh water during salt tide periods, which usually occur in spring and summer.

Another way of fighting the salt tides will be by controlling the water from the northern branch of the Yangtze River estuary into the southern one, the forum heard.

Experts said one of the main reasons for the salt tide was the salt water flow into the southern branch from the northern branch.

The city has carried out a project to increase water inflow and decrease the salt content of the northern branches, Shen Jun, vice mayor of the city, said.

Experts also suggested improving the ecological environment of the river mouth area.

The forum also issued a "Shanghai Statement" yesterday in which the 11 provinces and cities along the Yangtze River, the central government and organizations on environment and water protection agreed to cooperate on the use of river resources in order to protect one of China's major rivers.
