Orifice vs weir flow

WitrynaBentley SewerGEMS can also treat an orifice as one of the controlling elements in a detention pond composite control structure; other controlling elements within a composite control structure include weirs, risers and culverts. Orifices are treated the same as weirs to be internal boundaries except that the flow equation of an orifice is used ... Witrynathe volume of stormwater it treats for between 12 and 48 hours. Designing dry ponds with a high length -towidth ratio (i.e., at least 1.5:1) and incorporating other design features to maximize the flow path effectively increases the detention time in the system by keeping flow from short-circuiting the pond. Designing ponds with relatively
