MENDOZA MEJIA, Jesús Baruch  and  OROZCO HERNANDEZ, María Estela. BIOPHYSICS VULNERABILITY ANALYSIS TO FLOODING RISK IN THE METROPOLITAN AREA OF TOLUCA, MEXICO. Luna Azul [online]. 2014, n.38, pp.86-104. ISSN 1909-2474.

A multicriteria analysis of natural physical factors of the Toluca Metropolitan Area (ZMT) was performed in order to define the biophysical index of exposure to flood risk. Institutional information and field information was used for carrying out the work and it was processed through statistical and multi-criteria methods with the support of GIS and remote sensing. The results showed that the rate of high risk, with a 52.41% value includes the municipalities of Lerma, Toluca, San Mateo Atenco and Metepec, and covers an area of 1032.73 km². The low rate covers 13.71 % of the territory and an area of 13.71 km², and finally the average biophysical risk covers 687.20 km² or 33.88% of the metropolitan area. It is intended that the research results contribute to decision making in the fields of civil protection, regional development and public safety, as well as incorporation into urban development plans and land use planning with a view of risk, and be useful in the fields of civil protection, metropolitan development, public safety and land use planning.
