松嫩低平原小流域面积坡地设计洪水计算方法研究

摘要

Small area slope calculation for no design flood data area is a frequently encountered problem in the design of water conservancy project planning .The design flood survey calculation is the main way to solve the problem.Taking Nen River left low plain as an example, by using regional flood survey data;the empirical formulas is established,and then calculate the design flood of small watershed slope. Through rational analysis and comparison,it is universal and has practical value.%无资料地区小面积坡地设计洪水计算是水利工程规划设计中常遇到的问题。利用洪水调查推求设计洪水是解决该问题的主要途径。文章根据黑龙江省嫩江左岸低平原地区、利用区域洪水调查资料、建立经验公式。推求小流域面积坡地设计洪水，经对比及合理性分析证明具有普遍性，有一定的使用价值。
