摘要
无资料小流域设计暴雨洪水是该区域开展工程建设等项目的重要依据,因此合理地进行设计暴雨洪水推求,进一步科学地评定该区域的防洪排涝能力现状至关重要。本文以新昌县合溪江及方口两个小流域为例,对真诏村、方口村进行设计暴雨洪水推求。结果表明,针对大于50 km^2的小流域,瞬时单位线法更为合理;而针对小于50 km^2的小流域,推理公式法更为适用,对于浙江省类似地区设计暴雨洪水推求具有一定的参考价值。
As an important basis for the construction projects, that is crucial to calculate the design floodreasonably and evaluate the present flood control capacity of some basin scientifically. After analysis anddiscussion on case of Zhenzhao and Fangkou in this paper, the design achievements offer a reference forother similar basins, which show that instantaneous unit hydrograph is more appropriate for somewheremore than 50 km2, while reasoning formula method more suitable for somewhere less than 50 km2.
