                         objetivos deste trabalho foram: (I) estabelecer o significado da 
                         recente modifica{\c{c}}{\~a}o da legisla{\c{c}}{\~a}o 
                         florestal ocorrida em 2012, por meio da Lei n\$^{o}\$ 12.651, em 
                         rela{\c{c}}{\~a}o aos topos das eleva{\c{c}}{\~o}es; (II) 
                         desenvolver cen{\'a}rios de cobertura pret{\'e}ritos e futuros 
                         com diferentes n{\'{\i}}veis de degrada{\c{c}}{\~a}o 
                         florestal; e (III) analisar e comparar as respostas 
                         hidrol{\'o}gicas destes cen{\'a}rios de cobertura aplicando o 
                         modelo \emph{Distributed Hydrology Soil Vegetation Model} 
                         (DHSVM). No total, foram desenvolvidos seis cen{\'a}rios de 
                         cobertura, que s{\~a}o, em ordem decrescente de 
                         preserva{\c{c}}{\~a}o: (i) apresentando a vegeta{\c{c}}{\~a}o 
                         pristina; (ii) obedecendo as regras da Resolu{\c{c}}{\~a}o 
                         CONAMA 303/2002, conforme o aqui denominado Antigo C{\'o}digo 
                         Florestal (ACF); (iii) combinando as regras da 
                         legisla{\c{c}}{\~a}o anterior e da nova legisla{\c{c}}{\~a}o; 
                         (iv) obedecendo as regras da legisla{\c{c}}{\~a}o atual, 
                         denominada aqui de Novo C{\'o}digo Florestal (NCF); e dois 
                         cen{\'a}rios futuros consequentes desta nova 
                         legisla{\c{c}}{\~a}o, (v) um predominado por pasto e (vi) o 
                         outro por agricultura. Para isso, foram delimitadas as {\'A}reas 
                         de Preserva{\c{c}}{\~a}o Permanente (APPs) de topo de morro e 
                         montanha segundo o ACF (Lei n\$^{o}\$ 4.771 de 1965 - revogada), 
                         e tamb{\'e}m as APPs de topo de eleva{\c{c}}{\~o}es segundo os 
                         crit{\'e}rios do NCF, para a Bacia do Rio Verde, localizada no 
                         sul de Minas Gerais. Os mapas resultantes foram comparados e uma 
                         an{\'a}lise de adequa{\c{c}}{\~a}o foi realizada para verificar 
                         a vegeta{\c{c}}{\~a}o atual, cruzando um mapa de cobertura de 
                         2006 baseado em classifica{\c{c}}{\~a}o de imagem TM/Landsat com 
                         o mapa de APPs do ACF. O modelo DHSVM foi calibrado e validado com 
                         o mapa de 2006, que foi considerado como experimento Controle, e 
                         ent{\~a}o as respostas hidrol{\'o}gicas deste e dos 
                         cen{\'a}rios de cobertura foram comparadas. Foi observada uma 
                         rela{\c{c}}{\~a}o proporcional inversa entre a mudan{\c{c}}a da 
                         {\'a}rea florestada e a vaz{\~a}o no exut{\'o}rio da bacia, e o 
                         cen{\'a}rio predominado por agricultura apresentou vaz{\~a}o 
                         maior (por{\'e}m n{\~a}o significativa) que o cen{\'a}rio 
                         predominado por pasto, apesar de ambos possu{\'{\i}}rem a mesma 
                         extens{\~a}o de floresta. Diferen{\c{c}}as significativas nos 
                         processos hidrol{\'o}gicos em rela{\c{c}}{\~a}o ao Controle 
                         foram observadas apenas para o cen{\'a}rio de 
                         vegeta{\c{c}}{\~a}o pristina e o cen{\'a}rio baseado no ACF. 
                         Foi conclu{\'{\i}}do que o NCF diminuiu em 99,98\% a 
                         prote{\c{c}}{\~a}o dos topos de eleva{\c{c}}{\~o}es em 
                         rela{\c{c}}{\~a}o ao ACF e que as consequ{\^e}ncias 
                         hidrol{\'o}gicas podem ser detectadas pelo DHSVM numa bacia de 
                         mesoescala. ABSTRACT: There are currently many studies of 
                         distributed hydrological modeling that use land use/cover 
                         scenarios in an attempted to understand the influence of land use 
                         and cover changes on the watershed hydrology. There is still a gap 
                         on the hydrological consequences of the modification or 
                         non-fulfillment of forest legislation in Brazil, particularly in 
                         relation to hilltops at the mesoscale. The main objectives of this 
                         work were: (I) to establish the meaning of the recent alteration 
                         of hilltops protection status, caused by the change in forestry 
                         legislation that followed the review of the Federal Law number 
                         12651 that passed in 2012; (II) to develop past and future land 
                         cover scenarios with different levels of forest cover integrity; 
                         and (III) to analyze and compare the hydrological responses of 
                         these land cover scenarios with the application of the Distributed 
                         Hydrology Soil Vegetation Model (DHSVM). Six coverage scenarios 
                         were made, which are, in descending order of preservation: (i) 
                         presenting the pristine vegetation; (ii) complying with the rules 
                         of CONAMA Resolution 303/2002, called here as Old Forest Code 
                         (ACF); (iii) combining the rules of the previous legislation and 
                         new legislation; (iv) obeying the rules of the current 
                         legislation, called here the New Forest Code (NCF); and two future 
                         scenarios resulting from this new legislation, (v) one 
                         predominated by pasture and (vi) the other, by agriculture. For 
                         this, the Permanent Preservation Areas (APPs) of tops of hill and 
                         mountain were delineated according to ACF (Federal law number 
                         4771/1965 - repealed), and also the APPs of hilltops under NCF 
                         rules, for the Verde River Basin, located in southern Minas Gerais 
                         State. The resulting maps were compared and an adequacy analysis 
                         was conducted to verify the present vegetation, represented by a 
                         TM/Landsat based land cover map of 2006 as compared to the 
                         ACF\${'}\$s APPs map. The DHSVM model was calibrated and 
                         validated with the 2006 map, considered as the control experiment, 
                         and then the hydrological responses for the control and the land 
                         cover scenarios were compared. An inverse proportional 
                         relationship between the change of the forested area and the flow 
                         in outlet basin was observed, and the agriculture dominated 
                         scenario showed greater flow (but not significant) than the 
                         pasture dominated scenario, despite having the same forest extent. 
                         Significant differences in hydrological processes in relation to 
                         the control were observed only for the pristine vegetation and the 
                         ACF based scenarios. It was concluded that the current Forest Code 
                         decreased hilltop protection by 99.98\% in relation to the 
                         previous Forest Code, and the hydrological consequences can be 
                         detected by DHSVM in the considered mesoscale basin.",
