Abstract: A generalized mathematical model for the determination of morphological features of stable alluvial channels is presented in this paper. The model allows for the analytical treatment of extromal hypotheses, such as Minimun Strecm Power, Maximun Sediment Transport Rate and Maximun Friction Factor. The applicability of several transport and friction functions for the proposed approach is appraised, and its limitations are exposed. Furthermore, two sets of computer-based, regime-type, morphological equations are proposed for design purposes. Comparison of theoretical results with aivailable field and laboratory data is satisfactory, and shows the reliability of the approach.
