Southwest Water and Wastewater, 2005, 27(5): 19-22. (in Chi-nese) [10] 周丽. 浅谈广东省暴雨推求洪水计算方法及其实际运用[J]. 民营科技, 2008, 14(4): 19-20. ZHOU Li. The storm flood calculation method for Guangdong province and its practical application. Private Technology, 2008, 14(4...
The method determines a storm velocity and then checks the speed of storm features passing recording stations so deduced against the speed measured directly from hyetographs. Optimisation facilities are discussed by which machine processing time may be significantly reduced. The calculation of storm ...
A connection chamber for waste water and storm water collection, the connection chamber including an arch-shaped cut out in a side thereof, the arch-shaped cut out sized to receive an arch-shaped row connector, which is provided to couple rows of chambers to each other. The coupling of vari...
but the calculation results of flood peak and reservoir flood regulating are close to that out of Naci instantaneous unit hydrograph method which is not subject to limit of θ value.Therefore,calculating storm flood for special small watershed in Guangxi with reasoning formula is able to break the...
Select from a library of standard culvert shapes, materials, and entrance conditions, then compute culvert headwater and tailwater elevations using calculation methodologies outlined in Hydraulic Design Series Number 5 from the U.S. Federal Highway Administration. Design stormwater systemsMinimize capital ...

坡面汇流法计算小河流域暴雨洪水(第二部分)%Calculation of Storm Flood in Small River Basin by the Overland Flow Method(Part Two) 喜欢 0 阅读量: 52 作者: 关仲 摘要: 系统地介绍了一维水动力学(运动波)与水文学方法相结合的数学模型的算法原理.利用已知任意雨型的净雨时程分配,可以随之求出洪水流量...
For storm sewer hydraulic design, the design storm water runoff flow rate, Qdes, is usually calculated with therational method, based on adesign rainfall intensity. Also, a minimum flow velocity, Vmin, is typically specified for the case where the storm sewer is flowing f...
{Br}^{-}\)in macropores. However, since the PV of the individual soil columns are only rough estimates, they are subject to uncertainty. Therefore, the deviation from 50% solute breakthrough at a PV equals one could also be partly explained by the uncertainties in the calculation of the...
