Abstract: An optimizing program,including calculating and drawing,has been designed in this paper for thehydraulic calculations of waterway regulation projects. It is verified with the finished chuangjiang wa-terway regulation projects and can be broadly applied to the practical engineering.

Key words: waterway regulation, roughness, flow plan

摘要： 本文针对航道整治工程中所面临的复杂的、重复的、冗长的水力计算问题，采用数学模拟的方法，编制水力计算程序，并加以计算机绘图。该程序通过川江实测资料及河工模型试验的验证，具有广泛的应用价值。
