Organizing and summarizing search results for youCurb opening inlets are used in highway and city drainage systems. They have the advantage of being self-cleansing and hydraulic efficient. Here are some key points about curb opening inlets:- They are placed outside the travel way, posing less risk to motorists and bicycle traffic.
- Their capacity depends on water depth at the curb, curb opening length, and curb opening height.
- They are typically rectangular or trapezoidal in shape and fit within the curb line.

See more on learn.hydrologystudio.comThe capacity of a curb-opening inlet in a sag depends on water depth at the curb, the curb opening length, and the height of the curb opening. Curb inlets operate as weirs to depths equal to the curb opening height and as orifices at depths greater than 1.4 times the throat height. At depths in between, flow is in a transition stage.Storm Sewer Inlets – Learn Stormwater Studio
