MORPHOLOGY CHARACTERISTICS OF THE FLUVIAL LANDSCAPES FOUND IN MADRID
Abstract
The quantitative approach to landscape deseription has been a point of growing concem in the area of fluvial geomorphology, as a tool to use in land use planning. Following this line, we try to group the fluvial landscapes found in Madrid in morphologically homogeneous sets, on the basis of morphometric indexes and variables commonly used to study fluviallandforms, dealt with through multivariate analysis techniques. Another objective of the study is to find out which variables provide more relevant information in order to describe landscape geometry. Data were collected for 35 watersheds and measured at two different scales, 1:50.000 and 1:25.000. Five morphological sets of watersheds are defined, following three main gradients of variability, namely relief, watershed size and drainage network composition; the influence of the scale of maps from which data are collected is also analyzed.Downloads
