Interaction between GIS and hydrologic model: a preliminary approach using ArcHydro Framework Data Model

In different regions of Brazil, population growth and economic development can degrade water quality, compromising watershed health and human supply. Because of its ability to combine spatial and temporal data in the same environment and to create water resources management (WRM) models, the Geographical Information System (GIS) is a powerful tool for managing water resources, preventing floods and estimating water supply. This paper discusses the integration between GIS and hydrological models and presents a case study relating to the upper section of the Paraíba do Sul Basin (Sao Paulo State portion), situated in the Southeast of Brazil. The case study presented in this paper has a database suitable for the basin's dimensions, including digitized topographic maps at a 50,000 scale. From an ArcGIS®/ArcHydro Framework Data Model, a geometric network was created to produce different raster products. This first grid derived from the digital elevation model grid (DEM) is the flow direction map followed by flow accumulation, stream and catchment maps. The next steps in this research are to include the different multipurpose reservoirs situated along the Paraíba do Sul River and to incorporate rainfall time series data in ArcHydro to build a hydrologic data model within a GIS environment in order to produce a comprehensive spatial-temporal model.

Estratégias para disseminação do conhecimento organizacional: o papel da arquitetura da informação

Introduction: Organizations are expending more and more, the spaces electronic / digital (Internet / intranet / extranet) as a way to efficiently manage information and knowledge in the organizational environment. The management of inputs informational and intellectual belongings ranges from the strategic level to the operational level; the results demonstrate the strength of the socialization of organizational strategies. Objective: To reflect on the role of information architecture for the development of electronic spaces / digital in organizational environments. Methodology: Analytical study supported by specialized literature, based on three aspects emphasized by Morville and Rosenfeld (2006) and applied to information architecture: context, content and user studies beyond the search and use of information Choo (2006) which also highlights three aspects: situational dimensions, cognitive needs and emotional reactions. Results: In the context of the Web environment organizations have a large number of sites for brands / products that have mostly no organizational structure or shared navigation. The results show that when a department needs to contact another department must do so in order offline. Conclusion: The information architecture has become essential for the development of management information systems that makes possible to easily find and access data and information, as well as helps in developing distinct hierarchies to structure the distribution of content, promoting developed quality and effectiveness of the management systems.

Identificação de áreas potenciais para implantação de aterro sanitário no distrito de floresta do sul em Presidente Prudente/SP

O crescimento das sociedades urbanas tem gerado um aumento significativo na produção dos resíduos sólidos urbanos, tornando o tema de disposição final amplamente discutido nas gestões públicas. Recentemente, a partir da criação da Lei Federal nº 12.305/2010, que institui a Política Nacional dos Resíduos Sólidos, foi estabelecido que a disposição final ambientalmente adequada dos rejeitos deve ser feita exclusivamente em aterros. O presente trabalho teve então como objetivo a avaliação de áreas potenciais para instalação de aterro sanitário no Distrito de Floresta do Sul no município de Presidente Prudente/SP. Para tanto, utilizou-se o SIG, como ferramenta do geoprocessamento, para análise espacial. Inicialmente, construiu-se um banco de dados geográficos da região de estudo com os dados de geomorfologia, hidrologia, declividade, malha urbana e rede viária. Em seguida, foram geradas representações na categoria MNT, onde os valores foram normalizados em intervalos [0,1] através da lógica booleana e fuzzy...

Caracterização e mapeamento da cultura da cana-de-açúcar no município de Rio Claro (SP) por meio de técnicas de sensoriamento remoto e sistemas de informações geográficas

This paper discusses about the use of remote sensing image and processing digital images tools for mapping and assessing the effect on the biomass of the culture of sugar cane in the city of Rio Claro. We used satellite images from CBERS in the passages of 19/04/2009 and 23/09/08, which correspond respectively to the stages where the sugar cane appeared in growing and adult pre-harvest stage. In these images, we applied procedures of digital processing, as the application of the procedures for extending linear contrast, radiometric normalization, Normalized Vegetation Index (NDVI) and pixel by pixel classification by ISOSEG through of the software SPRING. As a result we obtained mapping of the distribution and development stages of the culture of sugar cane in the city of Rio Claro and the mapping of the existing biomass of this culture, showing that the method used to assess the relative effect on biomass in culture of sugar cane was efficient, and that images of low-medium resolution are not the most suitable for the mapping of this culture

Caracterização do grau de impermeabilização relativa das vertentes de uma bacia hidrográfica urbanizada: o exemplo do Córrego da Servidão - Rio Claro (SP)

The expansion and growth of towns affect the hydrology of watersheds included in the urban environment, impacting mainly the slopes and river channels. This interference can be in soil waterproofing, the runoff of rainwater, the extinction of surface drainage, the dynamics of flooding processes, etc. For studies concerning the hydrological behavior of watersheds, Remote Sensing techniques have been used to support the acquisition and analysis of data and also to generate new information from the integration of these data. In this context, the study aimed to characterize scenarios and conduct comparative analysis of urban occupation of parts of watershed the Córrego da Servidão, in Rio Claro (SP) and analyze the degree of waterproofing on the ground. With the support of the soil categories of waterproofing listed in Soil Conservation Service (S.C.S / USDA) this analysis was conducted, considering the scenarios of 1958 and 2006, through processes of interpretative analysis of panchromatic and color images aerofotogramétricas. The analysis, data integration and mapping of the watershed area were conducted in an environment of a Geographic Information System (GIS). Maps were obtained to characterize land cover in the watershed, showing the evolution of urban occupation, as well as indicating the densely built and waterproofed

Aplicação de técnicas de geoprocessamento para a avaliação da expansão urbana no municípo de Duque de Caxias (RJ) como subsídio ao monitoramento de dutos: trecho da faixa de dutos Rio de Janeiro - Belo Horizonte

Different forms of human pressure may occur in the pipeline ranges, due to the large extensions and various configurations of land use, which can pass through the pipelines. Due to the dynamics of these pressures, it is necessary to monitor temporal changes of land use and cover the surface. Under this theme, appears as extremely important to use products and techniques of remote sensing, as they allow the identification of objects of the land surface that may compromise the security and monitoring of the pipeline, and allows the extraction of information conditions on land use at different periods of time. Based on the above, this paper aims to examine in a temporal approach, the process of urban expansion in the municipality of Duque de Caxias, located on the outskirts of the metropolitan area of the state of Rio de Janeiro, as well as settlement patterns characteristic of areas that the changes occurred in the period 1987 to 2010. We used the technique of visual analysis to perform the change detection and the technique of image classification, aimed at monitoring human pressure over a stretch of track pipeline Rio de Janeiro - Belo Horizonte, located in the state of Rio de Janeiro. The stages of work involved the characterization of the study area, urban sprawl and the existing settlement patterns, through the analysis of bibliographic data. The processing of Landsat 5 images and the application of the technique of change detection were performed in three scenes for the years 1987, 1998 and 2010, while the classification process was performed on the image RapidEye for the year 2010. Can be noted an increase in urban area of approximately 22.38% and the change of land cover from natural to built. This growth is concentrated outside to the area of direct influence of the duct, occurring in the area of indirect influence of the enterprise. Regarding the settlement patterns of growth areas, it was observed that these are predominantly

SIG e álgebra de mapas na elaboração de um mapa de potencial de erosão em áreas de silvicultura

Cette étude visait à générer une carte du potentiel d'érosion pour la Ferme Santa Edwirges, située à Lorena /SP. Les résultats ont etés classifiés en faible, modéré, élève et très élève potentiel d'érosion et la carte obtenue a été comparé par rapport aux autres cartes existantes pour la zone d'étude. La méthodologie proposée se basant sur une application qualitative simple L’équation Universelle de Perte de Sol (USLE ou EUPS), en considérant les parties de l'équation: érodibilité, la topographie et l'utilisation des terres. Les donnés ont etés intégrés par l'algèbre de carte dans l’environnement SIG de ArcGIS. Pour la représentation de chacune de ces parcelles, nous avons utilisé une carte des formations superficielles de la ferme, généré à partir d'une ré-interprétation de la carte géologique, une carte de la pente et une carte d'utilisation des terres, attribuant un poids d’important pour chaque catégorie de ces cartes dans le processus d'érosion et dans l'algèbre proposée. Les résultats obtenus sont compatibles avec les zones identifiées comme les plus critiques sur terrain. La ferme a été identifiée comme de potentiel d'érosion modérée et la partie sud de la ferme le plus critique, suivi du groupe conduit par la zone de cisaillement, par contre les plaines proches des rivières ont eté identifié comme la zone plus stable avec moins de potentiel d'érosionDe la comparaison des résultats de ce travail et d'autres qui ont fait antérieurement dans la zone d’intéresse, qui ont utilisé les paramètres géotechniques dans la représentation de l'érosivité des sols, nous avons pu voir des résultats similaires, en particulier dans les zones à potentiel élevé et faible pour l'érosion. De la discussion et analyse des résultats, la méthodologie proposée à eté validée
