The objectives of.this study were to investiga.e the possibility of.predicting soil depth using som. terra.n a.tributes derived f.om.digita. eleva.ion m.dels （DEm.） with geogra.hic inf.rm.1}ion system. （GIS） a.d to suggest a. a.proa.h to predict other soil a.tributes.

The results indica.ed tha. the use of.m.ltiple linea. regression m.dels within sm.1}l wa.ershed subdivisions ena.led the prediction of.soil depth with a.dif.erence of.50 cm.f.r 77% of.the f.eld observa.ions.

Gettering by induced m.cha.ica. da.a.e is one of.the m.thods used in neutra.izing these im.urities.
