Affected by heavy rains, the flow of the three gorges reservoir, the rapid rise, 20 July 14, the three gorges flow 38000 cubic meters per second, outbound traffic fluctuation in about 23000 cubic meters per second, affected by reservoir detention, the three gorges reservoir water level rise gradually, 20, 20 when the water level rose to 156.85 meters.
Qingjiang, dongting lake lishui river, yuan river water increased rapidly and affected by the coming water from the river deltas, ensure the jianli ~ jiujiang Jiang Duan water levels rose, screw mountain, hankou railway station super alert again, a lotus pond water 21 will be the most high to 33 meters.
It is predicted that the flow of the three gorges reservoir, 21, 22, at 8 36000 cubic meters per second, 30000 cubic meters per second, respectively, in the future for a period of time, high temperature in most parts of the middle and lower reaches of the Yangtze river no rain.
Rainfall regime forecast, according to present situation of flood control and water by the participating experts for more than 10 a scheduling scheme are carefully compared, the office and the Yangtze river flood control decision, 21, 20 of the three gorges reservoir, the control analyzed 26000 cubic meters per second, when 22 at 8 control analyzed 28000 cubic meters per second, effective flood peak stagger the qingjiang river, dongting lake water system, reduce the pressure of downstream defense, at the same time to control the operation of the three gorges reservoir, the water level within a reasonable range, create favorable conditions for regulating water upstream. Late to strengthen consultation with the rolling forecast, at any time according to rainfall regime and water flood development, of the three gorges reservoir dispatching timely adjust.
