The purpose of highway drainage channels is to transport
excess water from the highway surface and surrounding
area to places of disposal, such as natural streams or other
declivities. Such channels constructed through local natural
materials must be designed to convey the prescribed
discharges without serious erosion of the boundaries. It is
the purpose of this report to discuss the characteristics of
flow in open channels and the means by which erosion resistant
channels may be designed. The suggested design
procedure as outlined is based on information and practices
that have been reported in the literature and on limited
experimentation in areas where the literature appeared to
be deficient in some respect. Stable channels represent a
special case of the sediment transport problem and much of
the data come from this discipline. A number of papers
(1, 2) on this and related aspects have been helpful in
organizing the data and developing the procedure.
