摘要
进行长江长寿段示踪剂岸边有限时段连续投放试验,求得横向扩散系数及其与流速、水深、流量、污染物浓度等关系。以长寿湖大沙坝河段为类比试验,预测得到三峡库区在90％保证率的最枯月流量下典型江段的横向扩散系数,并可用于库区的污染带计算。
Through continuous tracer throun tests along changshou Reach of Cha ngjiang River, the lateral diffusion coefficient and its relation with water velocity, dcpth, flow rate and the concentration of polluants are gotten.Taking the Dashaba River Reach of changshou Reservoir as the analogue test site, lateral diffusion coefficienf of typical reach of river under the flow of the driest month (90% guarantee rate) in yangtze. Gorges Reservoir Region in estimated.And this coefficient can be usedto calculate the pouution tome in this region.
