The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with flat and irregular topography. There is an apparent widespread misunderstanding of the concept of effective flow and its application especially in those situations that are not simple bridges. Examples are included to illustrate the proper application of the basic principles.
