Abstract

The research area of tthiis diisserttattiion iis representted by tthe area of iindiirectt iinflluence of Cana Brava Power Pllantt reservoiir tthatt presentts whiich exttends iittsellf for 1,,970,, 807 Km2.. Itt iis llocatted bettween tthe ciittiies of iin tthe ciittiies of Miinaçu and Cavallcantte iin tthe Sttatte of Goiiás.. The aiim of such research iis tto esttablliish tthe suscepttiibiilliitty tto llamiinatte erosiion iin tthe area from Cana Brava UHE,, and correllatted iitt allong tto enviironmenttall iimpactts and publliic healltth.. For tthe accomplliishmentt of tthe research,, iitt was made a dettached cutt iin tthe area of iindiirectt iinflluence from tthe reservoiir,, for whiich we have esttablliished 6 (siix) cattegoriies for tthe confecttiion of tthe suscepttiibiilliitty map based work CREPANI ett all..,, (2000).. The suscepttiibiilliitty map from tthe iindiirectt iinflluence area was generatted wiitth tthe iinttersecttiion of tthe geollogy,, geomorphollogy,, soiill,, and soiill use chartts,, and wiitth tthe I assiistt from declliiviitty chartt of tthe area,, by usiing geographiic iinformattiion systtem (SIG s ) and tthe SPRING 4..2 programs and ttheiir softtware compllementtary (Scartta and Ipllott ).. We fiind tthatt accordiing tto tthe declliiviitty chartts 35,,2% of tthe area presentts needs tto preservattiion acttiions case tthe soiill shoulld be used iin diisagreementt tto abiilliitty,, and around 47,,71% of tthe area presentts suscepttiibiilliitty tto llamiinatte erosiion neediing tto a riigiid conttrolls accordiing tto iitts use.. Itt s iimporttantt tto underlliine tthatt tthere iis iin tthe iindiirectt iinflluence area an area of enviironmenttall conservattiion,, and tthatt tthe regiion iis nott an iimporttantt centtre of cattttlle brewiing iin Goiiás.. The resulltts obttaiined sttands outt from tthe iimporttance of projjectts aiimiing tthe susttaiinablle devellopmentt tto tthe area,, tturniing iitt fundamenttall tto iitt preservattiion
