Consequently, calculating the intercepted runoff depth has become a problem that must be resolved immediately for initial stormwater pollution management. The accurate calculation of intercepted runoff depth provides a solid foundation for selecting the appropriate size of intercepting facilities in drainage ...

How does the Stormwater Utility fee calculation and billing work? The City has developed a rate schedule to ensure equity is reflected in the bills. All residential customers will be divided into six tiers based on the amount of runoff area on their property. Approximately, 50% of residential ...
Then, we summarize the characteristics of storm-runoff-typed disaster chains in Minjiang basin. 本文以闽江流域为研究对象,将GIS等现代地理研究手段运用于灾害研究,分析了闽江流域洪涝灾害的形成条件,分解出闽江各河段的灾害链的形成与类型,并总结出闽江流域暴雨径流型灾害链的基本特征,即:第一,上、下游分带性...
Provides complete TR20, TR55 runoff compatibility, Rational and Modified Rational methods. Create runoff hydrographs, combine, route and divert hydrographs. Interactive detention pond design. Best-in-class reports. Learn more about Hydrology Studio ...
The C3 guides have a calculation requirement of taking the total project areas and ensuring 4% of the impervious square footage flows to the treatment area. In an effort to store, treat, and collect all runoff, water was piped under the street, sent to a catch basin area, and then pu...
In the future, as part of a sustainable transportation system, it is expected that some transportation agencies may adapt the use of FDPPs for highway shoulders; especially for a more efficient and cost-effective methods of stormwater runoff management for highways. Under FDPP shoulder design ...
and P concentrations and ratios were then calculated as the mean of all sections in that core. Pond sediment C, N, and P concentration and ratios were calculated as the mean of all core concentrations from that pond. This method of calculation was used to prevent biasing pond values toward ...
runoff-producing events in their entirety or approximately a “two-year storm,” defined as a stormwater event that occurs on average once every two-years, or statistically has a 50% chance on average of occurring in a given year. Other methods for determining the capture volume can similarly...
However, little is known about the abundance or temporal variation of major ions in urban runoff. This study explores the spatio-temporal variation of major dissolved ions (Na, K, Ca, Mg, Cl, NO3, SO4) and total dissolved solids (TDS) in cold climate urban stormwater. Three watersheds ...
