Abstract

HENRIQUEZ, Cristián  and  AZOCAR, Gerardo. Cambio de uso del suelo y escorrentía superficial: aplicación de un modelo de simulación espacial en Los Ángeles, VIII Región del Biobío, Chile. Rev. geogr. Norte Gd. [online]. 2006, n.36, pp.61-74. ISSN 0718-3402.  http://dx.doi.org/10.4067/S0718-34022006000200004.

Through development of a spatial simulation model of the land use change it is evaluated and predicted the increase of the surface runoff coefficient in Los Angeles city, Biobío region, between years 1998 and 2022. The model has been developed in the SIG Idrisi Kilimanjaro integrating Markov Chains, Multi-Criteria Evaluation and Cellular Automata. The assessment of the surface runoff coefficient is based on the method of USSCS. The use of spatial models represents a powerful tool to analyze the environmental effects of the urban development, from a geographic approach.

Keywords : environmental assessment; spatial simulation; Geographic Information Systems.
