Weirs are structures consisting of an obstruction such as a dam or bulkhead placed across the open channel with a specially shaped opening or notch. The flow rate over a weir is a function of the head on the weir. Common weir constructions are the rectangular weir, the triangular or v-notch weir, and the broad-crested weir.
The velocity profile of a Power-law fluid is given by this equation. r is the radial position i.e. distance from the center line (m) R is the pipe radius (m) u (r) is the axial velocity (m s -1) dp/dz is the axial pressure gradient (Pa m -1) K is the flow consistency index (Pa s n) n is the flow behavior index.

sheet flow, 2-shallow concentrated flow, and 3-channel flow. Sheet flow travel time is likely to be the dominant component of the time of concentration for small watersheds. At the same time sheet flow estimation procedure is the most subjective and theoretically questionable of the three.
The term pipe flow in this course is being taken to mean flow under pressure in a pipe, piping system, or closed conduit with a non-circular cross-section. Calculations for gravity flow in a circular pipe, such as a storm sewer, are done with open channel flow equations, and will not be discussed in this course.
Time of Concentration and Travel Time Sheet flow Sheet flow is flow over plane surfaces. It usually occurs in the headwater of streams. With sheet flow, the friction value (Manning's n) is an effective rough-ness coefficient that includes the effect of raindrop impact; drag over the plane surface; obstacles such as
