RT Journal Article T1 Análisis cuantitativo preliminar de la cuenca hidrográfica del Río Grande (Málaga) mediante la utilización de sistemas de información geográfica T1 Preliminary quantitative analysis of the Grande river basin (Málaga) by GIS A1 Cobos Rodríguez, A. A1 Andreo Navarro, Bartolomé A1 Perles Roselló, M. J. AB This paper shows a preliminary quantitative analysis of the hydrological basin of Grande river (Málaga) using a Geography Information System (GIS). The analysis takes into account a description of the natural conditions and mainly spatial and form variables which are used to characterize the stream network and fluvial morphometry. A critical analysis of the results obtained in this work demonstrates that floods of Grande River represent a natural hazard basin because of its physical characteristics (i.e. form, altitude, slope and stream network) and the lithologies (the permeable carbonate rocl
