PROCESSOS EROSIVOS AVANÇADOS EM SÃO FRANCISCO DE ASSIS RS: ESTUDO DE CASO

Corrêa, Lourenço da Silveira Lima 29 June 2006 (has links)
The present paper analyses the erosive processes that have been developed in São Francisco de Assis county, between the peripheric depression and the Rio Grandense plateau. The studied area is located between the 55° 18'46"w and 55°16'00"w, 29°34'50"s and 29°32'55"s elose to, the new road RST 377. The study considers the drainage headcuts of a small hydrological basin connected to Ibicuí River, related to others in the neighborhood. The area is 357,72ha and the perimeter is 7929m. The purpose of this paper is to describe the gully and others erosive processes in different degrees of development, the factors that interfere in the origin and de evolution of the erosive processes in the region; to offer alternatives to stop the degradation of the erosive processes and the possible rehabilitation of the degraded areas, observing a restricted area. The identificated were elassified and maps were made. The erosive landforms have been studied by geomorphology alteration of the earth surface. l1's important to establish systems to observe the evolution of the erosive processes in arder to plan actions to preserve the productive areas and to stop the degradation of the environment in those areas and the around areas because processes like those are increasing in the whole region. / O presente estudo analisa feições erosivas que se desenvolvem em uma cabeceira de drenagem, no Município de São Francisco de Assis, entre a depressão periférica e o planalto Rio-Grandense. A área de estudo, localiza-se entre as coordenadas 55°18.46.w e 55°16.00.w e 29O34.50.s e 29O32.55.s, próxima a estrada nova (RST 377). O estudo avalia os processos erosivos em uma cabeceira de drenagem de uma bacia hidrográfica de pequena extensão associada ao Rio Ibicuí, comparada a outras bacias hidrográficas nas proximidades com área de 357,72ha e perímetro de 7929m. O objetivo do trabalho é descrever as voçorocas e outras feições em diferentes estágios de desenvolvimento, os fatores que intervém na gênese e a evolução dos processos erosivos na região; propor alternativas para contenção dos processos erosivos e possível reabilitação das áreas degradadas, observando uma área .modelo.. Foram identificadas, mapeadas e classificadas as voçorocas em vários estágios de desenvolvimento como também os areais e afloramentos rochosos. As feições erosivas são estudadas pela geomorfologia como as principais responsáveis pela modificação da superfície terrestre e como conseqüências do mau uso do solo. É importante implementar sistemas de informação que possam observar a evolução dos processos erosivos de modo a planejar ações para a preservação das áreas produtivas e conter a degradação ambiental na área e arredores, uma vez que processos semelhantes a esse se desenvolvem em toda a região.

Analysis of the Spatial Thinking of College Students in Traditional and Web-facilitated Introductory Geography Courses using Aerial Photography and Geo-visualization Technology

January 2014 (has links)
abstract: Recent advances in geo-visualization technologies, such as Google Earth, have the potential to enhance spatial thinking. Google Earth is especially suited to teaching landforms and geomorphological processes in traditional, online, or hybrid college classroom settings. The excitement for the technology as a learning tool, however, must be tempered by the need to develop sound and supportive pedagogies. A fundamental gap in the geoscience education literature exists because learning experiences with Google Earth, from the perspective of the student, are not completely understood. This dissertation analyzes three case studies in college introductory physical geography (Chapters 2 and 4) and teacher education (Chapter 3) courses at Arizona State University where students completed an online (Chapter 2 and 3) laboratory that used Google Earth as the main tool for landform identification and interpretation, and a hardcopy laboratory and in-field exercise (Chapter 4) that compared Google Earth oblique with traditional stereopair air photo and planimetric perspectives. Gauging student performance in these tasks, along with their formative and summative opinions for `what it was like to learn this way', provide information as part of a feedback loop to develop and improve instructional scaffolding and best practices so that the focus remains on the content-to-be-learned and not the tool. These case studies show that, in general, prior use of Google Earth is usually not a limiting factor; multiple perspectives and supplemental visualizations of landforms with Google Earth's may enhance the learning experience; the hands-on nature of structured Google Earth exploration in these labs are virtual field trips that increase enjoyment and fit within a learner-centered curriculum; scaffolding landform-learning exercises for aspiring elementary school teachers linked to children's literature assists the development of content knowledge for teaching physical geography and spatial thinking; and, finally, despite a virtual globe's high-quality visualizations and promising potential for learning, there is still a role for stereopair images in the geomorphology classroom. / Dissertation/Thesis / Doctoral Dissertation Geography 2014

The development and relative chronology of landforms at Kongsfjordhallet, Spitsbergen

Peterson, Gustaf January 2008 (has links)
Kongsfjordhallet is situated at 79° N on the North coast of Kongsfjorden, Spitsbergen.The landscape shows a large diversity of landforms and sediments and the aim of thisstudy has been to investigate the spatial distribution and temporal differences betweenthese landforms.The most prominent landform is interpreted as a lateral moraine dividing the area fromsoutheast to northwest. This is probably a sign of a standstill during the deglaciation ofan ice-sheet glacier tongue filling the fjord. The valley-glaciers at Kongsfjordhallet haveadvanced after this event and left end moraines on top of the lateral moraine. Largeamounts of meltwater have eroded parts of the Kongsfjordhallet, creating several fossilmeltwater channels that dissect the landscape. Erratic boulders of mainly gneiss type arescattered all over the landscape, as high up as 500 m a.s.l. In addition to the erraticboulders, a lot of allochthonous material is found incorporated in local material,especially as a diamict interpreted as till that covers large parts of Kongsfjordhallet.The till can likely be correlated to one of the diamict units in the cliff sections at theKongsfjordhallet coast. At present, two large ravines drain the area, moving water fromthe glaciers to the ocean and a beach is developing in the Southeast part of the area dueto ocean transgression. Landforms from two glacial events are found, one regional andone local. An episode of high sea-level as well as fluvial and mass-wasting activity afterthe deglaciation is also recorded. The formation of the landforms in the area is believedto be after the Last Glacial Maximum and into the Holocene, but no absolute dates areavailable. / SciencePub
