Natural Hazard Analysis in the Rivadavia Department, San Juan, Argentina

Abstract

The purpose of this research is to evaluate and zone the sectors exposed to various natural
hazards in the Rivadavia department, in order to support the bases for preventive and
corrective planning of natural threats, in favor of achieving sustainable urban development. To achieve these objectives, the methodological aspects initially involved direct contact with the Earth's surface through field reconnaissance; inventory and measurement of various geoforms and processes, through the comparison and evaluation of the natural conditions of the study area. To carry out the evaluation and cartographic digitization of the area, the implementation of a combination of variables was resorted to through Geographic Information Systems. To obtain significant results, analytical cartography was carried out that allowed, in successive stages, to specify a general synthesis-type cartography. The preparation of the analytical charts allowed the various variables to be captured and thus characterize the main spatial units of the study area, indicating a series of qualities manifest in the territory in relation to the dangers analyzed. Through the interrelation of the various variables, it was established that the department of Rivadavia presents two well-defined areas of global natural danger: a medium global natural danger in the eastern sector and high natural danger or high threat, in the western sector of the department
