Abstract: This paper shows how the critical flow section in a collector channel can be located by solving the dynamic equation of spatially varied flow, Manning's equation, and making use of the singular-point concept. In addition ...

Abstract: The current design procedure for sizing a single-unit curb opening inlet has been expanded to multiple-unit inlet designs. The decay function derived in this study can consistently convert a single-unit clogging factor to ...

Abstract: The street hydraulic capacity to convey storm water is dictated by the street gutter geometry and hydraulic characteristics. With the consideration of traffic safety, the street hydraulic conveyance capacity (SHCC) is also ...

Abstract: The operational cycle of a stormwater quality control basin can be divided into the waiting period between events and the filling and draining period during an event. In this study, an inherent overflow risk is defined as ...

Abstract: In this study, the rational method is expanded into the rational hydrograph method in which the time of concentration is considered as the system memory and the contributing rainfall depth to the present runoff rate is ...

Abstract: The design of a storm water detention basin requires both hydrologic and hydraulic information. The basic hydrologic data include the inflow hydrograph and the allowable release. The hydraulic information of a basin requires ...

Abstract: Low-impact development (LID) allows for greater development potential with less environmental impacts using on-site distributed storm-water controls that achieve a good balance among conservation, growth, ecosystem protection, ...

Abstract: Most storm water numerical models assume that the entire watershed area is covered by the design storm and shall be considered as the tributary area to the design point. Care must be taken when simulating storm runoff ...
