Diffusive processes such as creep, rain splash, and biogenic transport play a major role in controlling the development of convex hilltops on soil‐mantled landscapes. Although many diffusion‐based models have been proposed, little attention has given to effects changing rates boundary conditions. We use numerical analytical solutions one‐dimensional diffusion equation explore whether hilltop convexities can be equilibrium with contemporary climate local channel incision rates. The results...
Abstract. Various methods are currently used in order to predict shallow landslides within the catchment scale. Among them, physically based models present advantages associated with physical description of processes by means mathematical equations. The main objective this research is prediction using TRIGRS model, a pilot located at Serra do Mar mountain range, São Paulo State, southeastern Brazil. Susceptibility scenarios have been simulated taking into account different mechanical and...
Mass movements in Brazil are common phenomena, especially during strong rainfall events that occur frequently the summer season. These phenomena cause losses of lives and serious damage to roads, bridges, properties. Moreover, illegal occupation by slums on slopes around cities intensifies effect mass movement. This study aimed develop a methodology combines models shallow landslides debris-flows order create map with initiation volume runout distance. The area comprised two catchments Rio...
Soil ecosystem service (SES) approaches evidence the importance of soil for human well-being, contribute to improving dialogue between science and decision-making encourage translation scientific results into public policies. Herein, through systematic review, we assess state art SES in tropical regions. Through this 41 publications were identified; while most these studies considered SES, a lack consistent framework define was apparent. Most measured natural capital processes, only three...
Abstract Landslides are natural processes triggered by complex relationships between many conditioning factors. In Rio de Janeiro city, intense rainstorms combined with steep slopes, usually occupied slums, create favourable conditions for landslide generation. general, slope failures related to high positive pore‐pressures inside soil mantles, which associated topographic hollows and hydraulic discontinuities the deep weathered profile. This study aims characterize role played spatial...
Accurate mapping is a main challenge for endangered small-sized terrestrial species. Freely available spatio-temporal data at high resolution from multispectral satellite offer excellent opportunities improving predictive distribution models of such species based on fine-scale habitat features, thus making it easier to achieve comprehensive biodiversity conservation goals. However, there are still few examples showing the utility remote-sensing-based products in microhabitat suitability...
Deslizamentos são episódios de extrema importância, resultantes da atuação processos geomorfológicos nas mais diversas escalas temporais causando, em geral, enormes prejuízos à sociedade. Dentre os diversos fatores condicionantes destacam-se parâmetros morfológicos do terreno, quais controlam diretamente o equilíbrio das forças e, indiretamente, a dinâmica hidrológica dos solos. Embora muitos estudos tenham voltado atenção para descrição eventos e monitoramento campo, pouco ainda se sabe...
Abstract The effects of subsurface hydrology on the evolution erosive processes inside layered colluvium mantles in unchannelled valleys are investigated. Tensiometer nests installed different morphological conditions with their specific depths controlled by structure mantle. Daily readings (during one year) and physical mechanical analyses layers carried out. In spite a highly discontinuous structure, present topography is major factor controlling flow this landscape. Paleotopographic...
Inúmeras metodologias vêm sendo desenvolvidas com o intuito de entender os fatores que condicionam processo movimento massa. Neste propósito foi desenvolvido modelo SHALSTAB objetiva identificar e mapear as áreas instabilidade nas encostas. Essa metodologia tem como referencial a modelagem matemática baseada na combinação um hidrológico estabilidade Recentemente ela escrita em linguagem Avenue, implementada para utilização no Software ArcView. aplicada região do Quadrilátero Ferrífero (MG)...
Anthropogenic infrastructures and land-use changes are major threats to animal movements across heterogeneous landscapes. Yet, the behavioural consequences of such constraints remain poorly understood. We investigated relationship between behaviour Common genet ( Genetta genetta ) road proximity, within a dominant mixed forest-agricultural landscape in southern Portugal, fragmented by roads. Specifically, we aimed to: (i) identify characterise states displayed genets related movement...
