runoff formula 中文意思是什麼
runoff formula
解釋
徑流計算公式-
However, it lacks runoff data in absolutely most areas where culvert and small bridge locate. some traditional design method, such as the methods of statistic zone parameter, modification by catchment area, rainfall - runoff, reasoning formula and empiric equation et al, are used to estimate flood flow through culvert or bridge
然而，絕大多數中小橋涵所在地卻沒有可利用的徑流資料，通常採用統計分區法，面積改正法、暴雨徑流法、推理公式和經驗公式等傳統設計方法，這些方法一般比較繁瑣、精度較低、設計的流量偏大，導致工程造價偏高而浪費資金。 -
Based on theory of water travel in catchment and reasoning formula, a new calculation model for flood flow design of culvert and small bridge in sichuan hilly area where is no runoff data is derived in the paper
因此，本文以著名的流域匯流公式為主，引入推理公式的思想，進行合理的概化導出了適合於四川丘陵地區無徑流資料的中小橋涵設計洪水計算的新模型。
