苏联疆域辽阔,水资源丰富,河川年平均径流量47,140亿米~3,人均年径流量约17,500米~3。地下水的每年可开采量估计有2,200亿米~3。苏联是世界上水能资源丰富的国家之一,可开发水能资源约为10,950亿度(据1974年世界能源会议资料,后经普查,又有所增加),约可装机2.7亿千瓦(不包括抽水蓄能电站),仅次于我国,居世界第二位。苏联在水利水电建设方面,也走过不少弯路,有不少教训。例如,德聂伯水电站建成时(有不少外籍专家参加建设工作),高压线路没有架设好,初期电送不出去,机组在厂房里停着,而水流只能通过溢洪道下泄,白白浪费水能。伏尔加河上的梯级电站工程艰巨,工期
The vast territory of the Soviet Union, rich in water resources, the annual average runoff of river 4714000000000 ~ 3, average annual runoff of 17,500 meters ~ 3. The annual recoverable groundwater is estimated at 2,200 billion m 3. The Soviet Union is one of the countries with abundant hydropower resources in the world. The hydropower resources that can be exploited are about 1095 billion kilowatt-hours (according to the World Energy Conference in 1974 and later increased by census), about 270 million kilowatts can be installed Including pumped storage power station), second only to China, ranking second in the world. The Soviet Union in the water conservancy and hydropower construction, has also gone through many detours, a lot of lessons. For example, when the Dneeb Hydropower Station is completed (many foreign experts participate in the construction work), the high-voltage lines are not erected and the initial electricity can not be sent out. The units are parked in the plant and the water flow can only be discharged through the spillways, thus wasting water . The cascade hydropower project on the Volga River is arduous and time-consuming
