The geometric characteristics of a basin can influence the runoff and drainage, which justifies its evaluation based on correlation between measurements (morphometry). Rounded Watershed can be fully covered by rainfall and concentrate water in less time, the branching may suffer peaks between flow and concentration and may present elongated profile and balance between flood flows. We carried out the delimitation and morphometric characterization of the Cobiça Stream watershed by applications of Geographic Information System (ArcGIS 9.1\uae), followed by the correlation between the data and parameters identified with the history of flooding in the area. The digital database used consisted of hydrography and contour mapped and orbital images (HRC-CBERS 2B). The geometry and the morphometric indexes ...

These are areas defined by specific criteria, forming a barrier against potential natural vegetation changes to natural resources. The anthropic causes imbalance in environmental systems, due disruption their dynamic balance, making them vulnerable to external factors. The vulnerability study of environmental systems can be accomplished from inferences from the occurrences of your surroundings (multicriteria analysis), whether by proximity or by their proportion of the spatial distribution. The Geographic Information Systems (GIS) software to specific generation, processing and storage spatial data from different formats (vector and matrix) capable of automatically identifying or defining factors interest. In this work, we carried out the demarcation PPA (buffer) of Lake Guanandi environment in ...

Due to the complexity of processes related to occurrences of erosion, several proposals have been adopted to find a suitable modeling, with the intention of generating a physical description and mathematical loss of soil by erosion. The Universal Soil Loss Equation (USLE) expresses the action of the main physical and geographical factors (PS = R * K * L * S * C * P) that influence water erosion. Delimitation of Permanent Preservation Areas (APP) aims to protect natural resources and the isolation of overgrowth, so that they perform their ecological and environmental functions. This paper presents an estimate of the potential impact of APP on water erosion in the catchment of the Rio da Prata, Castelo (ES). For this, we used the USLE in a Geographic Information System (GIS) environment, considering two scenarios: the actual land use and adoptio...

Anthropogenic activities in the surroundings of conservation units can proffer its risks physical area and ecosystem species, making these vulnerable by border effect.

Water erosion is the most common, caused by effective precipitation basin, since its potential is the main agent of reshaping the land. Universal Equation Soil Loss (USLE) show great applicability to estimate erosion in watersheds from their physical and geographical elements (PS = R*K*L*S*C*P). The intensity of erosion can be influenced by the profile of the slope, measured by the length (L) and grade of slope (S). The topographic factor (LS) of the USLE is the most difficult to obtain for large and/or diverse relief areas. We calculated the spatial map of the LS factor Silver watershed (Castelo-ES) from the processing of cartographic data in environment Geographic Information Systems (GIS). The relief of the study area was represented by interpolation from contour lines supported mapped hydrography, give the digital elevation model h...

Correlaciona as atribuições do geógrafo com outras categorias profissionais, evidencia sua baixa representatividade no mercado e fatores que limitam seu reconhecimento e desempenho profissional. No cenário de constantes e intensas transformações, que priorizam as tecnologias e profissionais técnicos e pragmáticos, é notória a ascensão dos cursos de engenharias. A proposta da engenharia geográfica não é vista como mais uma tendência, e sim como opção para promover autonomia, superar crises, capacitação tecnológica e um eficiente desempenho profissional.

Nele são abordados fundamentos, conceitos e métodos. Delimitam sua história os períodos de uso de sistemas fotográficos, a evolução e a multiplicidade dos sistemas imageadores. Descrevem-se princípios e métodos necessários para correção, tratamento, interpretação visual, avaliação de parâmetros das imagens e cruzamento de dados aplicados a estudos de índices de vegetação (NDVI) e de paisagens. A eficácia dos estudos da vegetação via sensoriamento remoto é embasada pelos resultados e pelas considerações obtidas por revisão conceitual, que priorizou a consulta a periódicos especializados.

A erosão hídrica é a mais comum, ocasionada pela precipitação efetiva em bacias, que devido ao seu potencial erosivo é o principal agente de remodelagem do terreno. A Equação Universal de Perdas de Solos (EUPS) mostra-se de grande aplicabilidade para estimar a erosão de bacias hidrográficas a partir de seus elementos físicos e geográficos (PS=R*K*L*S*C*P). A intensidade da erosão pode sofrer influência do perfil da encosta, avaliada pelo comprimento (L) e grau do declive (S). O fator topográfico (LS) da EUPS é o de mais difícil obtenção para áreas grandes e/ou de relevo diversificado. Realizou-se a espacialização do mapa de fator LS da bacia da Prata (Castelo-ES) a partir do processamento de dados cartográficos em ambiente de Sistemas de Informação Geográfica (SIG). O relevo da área de estudos foi representado via interpo...

Planning guided by the occupation and mitigate the impacts of flooding can avoid disasters and losses, the example of unconventional measures by engineering works.

As mandated by state law, water-use data are reported by ground-water withdrawers annually to the Arkansas Soil and Water Conservation Commission, and stored in the Arkansas Site-Specific Water-Use Data System provided and supported by the U.S. Geological Survey. Although most withdrawers are able to provide the amount of water withdrawn and the depth of their wells, very few are able to provide the name of the aquifer from which they withdraw water. GIS software was used to develop an automated procedure for identifying the primary aquifers supplying ground water to individual wells in eastern Arkansas. The software was used to generate a spatial representation of the bottom boundary for the Mississippi River Valley alluvial aquifer (the shallowest aquifer) in eastern Arkansas from well log-data collected by the U.S. Geological Survey. The software was then used to determine the depth of the aquifer bottom at reported well locations to ascertain whether the Mississippi River Valley alluvial aquifer or a deeper aquifer was the primary aquifer providing water to each well. The alluvial aquifer was identified as the primary aquifer for about 23,500 wells.
