Outlet control is the opposite and happens when the inlet can … Webb5.3 Outlet Control Flow through a culvert is outlet controlled if the relationship between discharge and headwater is determined by the barrel characteristics and, sometimes, the tailwater level. In this case, the discharge is limited by the barrel and the inlet is larger than necessary. The culvert will therefore ﬂow either full or subcritical. sue harmony spa pawtucket hearing court
