Sumario:We evaluated and discussed alternatives to erosion susceptibility chart production according to different weights for physical environment attributes. Four techniques were used: landform, terrain steepness, soil, rock, land use and occupation. The following combinations of attributes were discussed: equal weights for physical environment attributes, different weights according to an expert in Prosa Basin, different weights according to other researchers, and different weights obtained through an analytical hierarchical process (AHP). The studied area comprises Prosa Basin in Campo Grande (Mato Grosso do Sul, Brazil). Results show that the considered alternatives can be used as a group or in different stages to support urban planning.
