Abstract: Channelization and navigation training project of reservoir areas is an effective path for mountainous rivers navigation development． However，mountainous rivers have large variation range of water level and poor water flow patterns，therefore it is very difficult to determine the design parameters of navigable water level，flow and amplitude level． With navigation design of mountainous rivers channelization，e． g． in Wujiang River，the calculation of navigation discharge and water level were studied; management measures for meeting demands of navigation of downstream channel and ports were proposed．

Key words: mountainous rivers, cascade canalization, navigation discharge, amplitude level, Wujiang River

摘要： 梯级渠化结合库区航道整治工程，是山区河流航道建设的有效途径。但由于山区河流洪水期陡涨陡落、水流 形态较差，梯级电站通航设计中通航水位、流量、水位变幅等参数的合理确定较为困难。结合山区河流通航设计实 践，以乌江为例，研究了枢纽通航流量及相应水位计算方法，提出了满足枢纽下游航道及港口要求的对策措施。
