ABSTRACT: The morphometric parameters are of fundamental importance for the good operation of models, among them, the area of the basin to amount determined for each pixel stands out for releases use in hydrologic models used for the definition of saturation areas in the landscape and predictive models of mass movements. In this work three different ways are compared of obtaining the delimitation of hydrologic basins starting from a digital elevation model: a) Directly of DEM without any treatment type, being used of different interpolators types; b) Starting from the elimination of the depressions inherent of the interpolator that doesn't correspond to the nature and; c) Making DEM being used of the corresponding vectors the drainage net and water bodies, being eliminated, also, the depressions. The results show that the values obtained by the different processes possess significant discrepancy amongst themselves. |

The experimental farm of Embrapa Grape and Wine in Bento Gonçalves, state of Rio Grande do Sul, Brazil is part of the Taquari-Antas watershed is included in the Biosphere Reserve of the Atlantic. In this place develops activities occupying an area of ninety-four hectares. 67.34% of this area is covered by native forest and secondary vegetation, which were established as Legal Reserve Area (ARL) and Permanent Preservation Area (APP). The establishment of the drainage framework generated from the high-resolution digital elevation model (DEM), and native forest, were drawn APP (for permanent preservation areas) and legal reserve of rural property. The land cover conflict in the area of this farm regards to buildings near the areas of preservation are being framed in accordance with a proposal for preservation and restoration with native species. Through software SPRING 5.0.1, it was possible to carry by construction of georeferencing maps through crossing vectors for the land use conflicts analysis, the limits and the related drainage framework with APPs and RL with the identification of the springs. These data had been produced from high resolution aerialphoto image analysis, DEM generated from the aerial restitution and it is part of the data base image of the Laboratory of Remote Sensing and Geoprocessing - Embrapa Grape and Wine. |
