Abstract
A detailed geomorphological study of the Chilean coastal area of the Strait of Magellan aimed at the determination and description of different coastal environments and related processes. The survey data have been compiled in a map that outlines the influence of glacial history in the coastal landscape development. Sea-bed characteristics such as bathymetry and sedimentology, together with information on tides, direction and magnitude of currents are also presented in the map. A subdivision of the coastal area was carried out dividing the coastline into 40 homogeneous segments, each described by 15 representative morphological and physical variables. By means of multivariate analyses of the data matrix six coastal groups subdivision was obtained. Groups were reviewed and re-interpreted in order to highlight relationships between coastal landforms and variables. Three factors fully describe the main coastal types and constraints. First factor groups the inherited coastal landforms, that...I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
