Brazil has a semiarid, considered the most problematic of the world, either by pressure from physical factors, whether as a result of misguided public policies, has over time been suffering from the consequences of a deterioration that expands over the years. Methodologies, that amidst the problems of semi-arid, come against the deteriorating local, have a good chance to be reapplied in other contexts around the world. This research, based on methodological model for analyzing environmental deterioration, introduced and examined the applicability of the methodology in the semi-arid region of Rio Grande do Norte - Brazil. Although the results provide guidelines for the introduction of underground dams, the application of the methodology was ineffective, given the high rates of forest cover that gave low values for the physical diagnosis conservationist / No mundo contempor?neo a deteriora??o das ?reas semi-?ridas do planeta tem sido foco da aten??o da m?dia e da comunidade cient?fica. O Brasil possuindo um semi-?rido, considerado o mais problem?tico do mundo, seja por press?es dos fatores f?sicos, seja como conseq??ncia de pol?ticas p?blicas equivocadas, tem ao longo do tempo sido v?tima das conseq??ncias de uma deteriora??o que se amplia com o passar dos anos. Metodologias, que em meio ? problem?tica do semi-?rido brasileiro, venham de encontro a deteriora??o local, t?m boas probabilidades de serem reaplicadas em outros contextos ao redor do mundo. A presente pesquisa, tendo como base modelo metodol?gico de an?lise de deteriora??o ambiental, introduziu e analisou a aplicabilidade da metodologia no semi-?rido do Rio Grande do Norte Brasil. Embora os resultados encontrados fornecerem diretrizes para introdu??o de barragem subterr?nea, a aplica??o da metodologia se mostrou ineficaz, haja vista os altos ?ndices de cobertura florestal que proporcionaram valores baixos para o diagn?stico f?sico-conservacionista
