钱塘江主源出自安微省休宁县大尖山岭北麓的板仓,往东北流贯浙江省北部,至澉浦经杭州湾入东海。澉浦以上河长约500公里,流域面积50100平方公里。流域来水丰沛,流清沙少。根据潮区界芦茨埠站资料统计,多年平均年径流总量为291亿立米,多年平均年输沙量500万吨。天然径流的年内分配很不均匀,4、5、6月份梅汛期水量约占年总量的50%;最大洪峰流量达29000立米/秒(1955年),枯季最小流量为15.4立米/秒(1934年);7～9月为台风雨季节,但产生较大洪水的机会不多。自新安江电站建
The main source of the Qiantang River comes from the Itakura warehouse at the northern foot of Dajianshanling, Xiuning County, Anwei Province. It runs northeast through the northern part of Zhejiang Province and reaches Xupu into Hangzhou Bay into the East China Sea. Tau Pu River about 500 kilometers above the river basin area of 50100 square kilometers. Watershed abundant water, clean sand less. According to the data of statistics of the station of Luzbu Port in the tidal zone, the average annual runoff for many years totaled 29.1 billion cubic meters, with an average annual sediment discharge of 5 million tons for many years. The distribution of natural runoff during the year is very uneven. The water volume in May, June and May is about 50% of the annual total; the maximum peak flow reaches 29,000 cubic meters per second (1955) and the minimum flow rate in dry season is 15.4 cubic meters per second 1934); July-September is the typhoon rainy season, but there are few opportunities for greater floods. Since the new Anjiang power station built
