中文摘要：

内河航运是综合运输体系中的重要组成部分，然而由于受季节性等影响，内河航道变化较大，容易导致碍航现象发生，影响内河航运安全畅通和运行效率。针对枯水期内河航运特点，研究了内河航道建模及航行仿真方法。提出了一套内河航道建模、水面生成和船舶随机产生方法，为研究枯水期提高内河航道通行效率、保障安全畅通提供了一个有效的平台。

英文摘要：

Inland water transport is an important part of the integrated transportation system; however, congestion and obstruction often occur due to seasonal changes in inland waterways, which affect the safety and efficiency of inland transport. Specific to the characteristics of dry season inland transport, this paper proposes a set of approaches on inland channel modeling, water surface generating and random vessel generating, which provide an effective platform for efficiency and safety improvement studies of dry season inland transoort.
