Unidades de Landforms na Bacia do Arroio Cadena, Santa Maria - RS

Abstract

This work uses the methodology proposal by Lollo (1996) to define in the basin of the stream cadena two landforms systems based on the geomorfological process, denominated as dissection and of accumulation areas. These systems were divided in smaller portions of the land, that for its time they are characterized by seven units, described in terms of morphologic features, types of you are worth, characteristic of the relief (altitude, amplitude, declivity), drainage, substratum geologic/pedological, use and occupation of the soil. We has for objective to give a contribution for the scientific knowledge of to how planning the use and occupation of the soil. Lhe analyzing data were integrated with relationship into the natural and anthropic way, identifying the main geomorphological processes.

Proposal Methodology for Analysis of Population Vulnerability at Hazard Areas

“…The cartographic base was created by the Geotechnical Units of Santa Maria, on the scale 1: 25,000 (Maciel Filho, 1990); political-administrative maps of the city on the scale 1: 15,000; as well as thematic zonings carried out in previous works (Avila & Robaina, 2014;Oliveira, 2004;Robaina et al, 2002).…”
