天山北坡中小流域设计暴雨洪水及自动化计算

Automatic Computing of Design Storm and Flood in North Slopes of Tianshan Mountains

天山北坡玛纳斯河以东地区的设计暴雨洪水计算主要采用《中小流域设计暴雨洪水图集》中的调蓄经验单位线法,经历查算设计暴雨、试算产流历时、得出净雨过程、使用调蓄经验单位线进行汇流计算,最终得到设计洪水过程。计算过程比较复杂,且带有主观随意性,计算结果缺乏唯一性。为了解决这些问题,更高效地进行设计洪水计算,现使用Visual Basic软件编程,实现了设计洪水的自动化计算,减少了设计洪水计算的工作量,提高了设计洪水计算速度和精度。

The design storm and flood calculation for East region of Manasi River in North Slopes of Tianshan Mountains mainly depends on Pondage Empirical Unit Hydrograph Method, which comes from Atlas of Design Storm and Flood tor Medium and Small Basins. The process of design storm and flood derives from the calculation of design rainstorm, the tentative calculation of runoff duration time, the estimation of net rainfall process and concentration calculation by using Pondage Empirical Unit Hydrograph. The calculation process is quite complex and subjective, and the calculation results lack of uniqueness. In order to solve these problems and to calculate design flood more efficiently, the automatic flood computing is implied by compiling program in Visual Basic, which reduces workloads of computing and thus improves the speed and accuracy of design flood calculation.
