O processo de ocupação por favelas e sua relação com os eventos de deslizamentos no Maciço da Tijuca/RJ
AbstractTijuca massif is marked by mountainous relief which can be devided into five great hydrographic sub-systems (sectors), with They have a different abiotic, biotic and occupation arrangement. This structure is consequence of massif's condition in Rio de Janeiro occupation process. This way, the study to searched understand the importance of slums ocupation in the city expansion in massif direction, and your relation with hydrological and erosive dynamic in study area and lowlands. The results show that slums ocupation in massif's slopes started in the end of last century. Nowadays, slums ocupation is large in sectors which are most degraded with regard to forest coverage substitution (1 and 2), showing the potentiality of this direct vector. Another problem in this kind of occupation is that generally slums location are in the base of hollows, where occour water subsuperficial recharge and increasing landslides probability. About landslides were noted an proportional increasing with regard to enlargementing or appearing of slums.
