Abstract
The specification of flow resistance is central to both simple and sophisticated hydraulic analyses. Yet it remains encumbered with the greatest level of uncertainty of all hydraulic parameters; despite over a century of field and flume experimentation. The selection of resistance coefficients for natural rivers remains more an empirical art than a matter of implementing robust scientifically verified procedures (Yen, 1991). The complexity and variety of boundary conditions are the principal impediments to developing reliable resistance estimation tools. A range of boundary features contribute to flow resistance and, of these, vegetation is the most potent (Cowan, 1956; Watson, 1987) but the..
