Abstract : Thirty-four major river systems were compared in terms of the morphology and process environments of their drainage basins, alluvial valleys, receiving basins, and delta plains. Data for a multitude of variables, were generated and compiled for each of the 34 systems. These data were stored in a systematic hierarchical arrangement in a comprehensive information-storage-and-retrieval computer system. For purposes of comparisons between river and delta systems, optimum combinations of salinent variables were selected and were subjected to multivariate statistical procedures, including factor analysis, cluster analysis, and discriminant analysis. The procedures established the existence of some discrete groups of river systems and facilitated quantitative assessment of the degrees of mutual similarity or dissimilarity between individual river systems and between groups of two or more systems.
