/ 84 办法0 是安徽省水利部门在中小流域( 10~ 300 km2 ) 洪峰流量计算中的常用方法, 但在特小流域中( < 10 km2 ) 的应用较少。以安徽省马鞍山市雨山现代农业示范园内的防洪渠设计洪水分析计算为例, 将/ 84 办法0 与特小 流域中计算洪峰流量常用的两种方法即中国水科院1958 年推理公式法和中国公路科学研究所经验公式法进行比 较、分析与讨论, 认为/ 84 办法0 在特小流域洪峰流量计算中的应用是合理可行的。

The 84 metho d is commo nly used in the ca lculatio n o f peak dischar ge in medium and small w atersheds ( 10~ 300 squar e kilometers) by the water conserv ancy depar tment o f Anhui, but it is seldom used in the extr a small w atershed ( less than 10 squar e kilometer s) . In this paper, the design f loo d of the floo d contr ol channels in Yushan modern ag ricultural demonst ratio n par k o f Ma. anshan in Anhui w as calculat ed using the 84 Method and t wo ot her commo n fo rmulas, including the 1958 hydro log y reasoning fo rmula o f the China Inst itute of Water Resources and Hy dr opow er Research Institut e and t he ex per ience fo rmula of the Scientific Resear ch Institute of H ig hway . The r esults sugg ested that applicatio n o f the 84 method in the calculation of peak discharg e of ex tra small w atersheds is reasonable and feasible.
