MORPHOMETRY OF FLUVIAL NETWORKS: CRITICAL REVIEW OF THE MOST COMMONLY USED PARAMETERS AND THEIR APPLICATION TO THE UPPER GUADALQUIVIR
Abstract
A critica1 review of the strength of each parameter commonly used in morphometric studies of drainage basins is presented. At the same time the most significant parameters, when studying the morphometry of the headwaters of the Rio Guadiana Menor in the Upper Guadalquivir, are presented. Following an initial study of 42 variables grouped under relief, length, geometry and fluvial intensity, and subjected to factor analysis, 9 variables were finally selected; confirming that these variables characterize well the drainage basin for which they were studied. Using nine variables the loss of information is minimal and the time needed to undertake the morphometric analysis is reduced considerably.Downloads
