Integrated analysis of natural hazards in the coastal semiarid environment of Chile. La Serena, Coquimbo

Abstract

We identify the landscape units most prone to natural hazards that frequently strike the Coquimbo bay. The research was based on geomorphological processes and soil infiltration capacity. Also, some proxies realized by means of GIS techniques have been used. The highest marine terraces are not subject floods and debris flow hazard; the lowest marine terrace present he worst hazard conditions to floods due overflowing river and the low soil permeability
