Atlas interativo do Pontal do Paranapanema : uma contribuição à educação ambiental /

Meneguette, Arlete Aparecida Correia. January 2001 (has links)
Resumo: A área do Pontal do Paranapanema está localizada no Extremo Oeste do Estado de São Paulo, na região sudeste do Brasil, em uma posição estratégica considerando tanto sua proximidade com os Estados de Mato Grosso do Sul e Paraná quanto o advento do Mercosul - o mercado comum do Cone Sul. No Estado de São Paulo há três áreas muito carentes, uma das quais é o Pontal do Paranapanema, onde têm havido muitos conflitos sociais relativos à posse e propriedade da terra, envolvendo disputas entre o Estado e os latifundiários. Nos últimos anos os trabalhadores rurais têm realizado ocupações nesta região e reivindicado terras - eles criaram um grupo denominado MST (Movimento dos Trabalhadores Rurais Sem Terra), que tem ganhado popularidade e apoio de vários segmentos da comunidade, estando diariamente na mídia (jornais, TV etc). A comunidade acadêmica tem estado consciente e preocupada com esta situação e, portanto, tem desenvolvido estudos e pesquisas sobre o assunto, tanto individualmente quanto através de grupos de pesquisa. Uma das mais importantes Universidades Brasileiras é a Universidade Estadual Paulista (unesp), que tem um de seus campus localizado no município de Presidente Prudente (o qual está localizado no Pontal do Paranapanema). Desde a década de 1960 diversos pesquisadores têm desenvolvido pesquisas técnico-científicas almejando produzir um Atlas do Pontal do Paranapanema em formato convencional. O principal objetivo seria o de reunir, através de mapas topográficos e temáticos, todas as informações geográficas sobre o Pontal do Paranapanema, a fim de servir de base para projetos e planejamentos governamentais (municipais ou estaduais), bem como para o setor privado. O Atlas seria também um produto de informação sobre os recursos naturais e as condições sócio-econômicas desta área, sendo voltado para estudos acadêmico...(Resumo completo, clicar acesso eletrônico abaixo) / Abstract: The Pontal do Paranapanema area is located in the western part of São Paulo State, in the southeast of Brazil, in a very strategic location considering both its proximity to the states of Mato Grosso do Sul and Paraná and the advent of Mercosul - a common market for the South. In São Paulo State there are three very poor areas, one of them is the Pontal do Paranapanema, where there have been many social conflicts concerning the ownership of land, involving disputes between the State and the farmers. In the last few years the rural workers have established temporary settlements in this region and are claiming for land - they created a group called MST (Landless Workers Movement), which has gained popularity and support from many segments of society, being in the media every day (newspapers, TV etc). The academic community has been aware of this situation and also concerned about it therefore studies and researches have been carried out about the subject, either individually or through research groups. One of the most important Brazilian universities is São Paulo State University (unesp) that has one of its campuses located in Presidente Prudente (which is in the Pontal do Paranapanema area). Since the 1960's many researchers have been carrying out technical and scientific activities, which aim at the production of a hardcopy version of the Pontal do Paranapanema Atlas. The main objective would be to bring together, through topographical and thematic maps, all the geographical information about the Pontal do Paranapanema, in order to serve as a basis for studies and planning of the government (at municipal and state level) as well as to the private sector. The Atlas would also try to become an information product about natural resources and socio-economic conditions of this area directed to academic studies of the regional community. After four decades since the first...(Complete abstract click access electronic below)

Peligrosidad de las aguas de avenidas en los cruces de carreteras con ramblas. Estudio aplicado a la franja costera meridional de la región de Murcia

García Lorenzo, Rafael 17 December 2010 (has links)
Los objetivos de la presente tesis son la identificación de la peligrosidad en las intersecciones de ramblas con carreteras, y la aplicación de diferentes índices, producto de análisis cuantitativos y valoraciones cualitativas basadas en un extenso trabajo de campo reunido en fichas descriptivas. Se analizan las diferentes obras de drenaje que afectan al área de estudio, sus funciones y requerimientos para optimizar el tipo de diseño, la ubicación y la eficiencia de las obras de drenaje transversales a los flujos de avenida. Ello sirve de base para conocer la peligrosidad de los cruces de carreteras con ramblas que depende del nivel de exposición de las infraestructuras viarias y del tipo de cruce de carretera.Para la obtención de datos de caudal se ha empleado el método del hidrograma unitario (MHU) y el método racional modificado (MRM), así como la integración de métodos de geometría hidráulica y técnicas de teledetección. Complementariamente, se ha realizado una modelización hidráulica y la aplicación de modelos empíricos para la estimación de la erosión del lecho y transporte de fondo.Otro objetivo del estudio es la definición de propuestas de gestión de los datos sobre peligrosidad orientadas a estrategias y planes de protección civil. El uso de visores por parte de las autoridades competentes, la integración, mantenimiento y manejo de los datos, así como la creación de un Atlas interactivo de peligrosidad hidrológica e hidromorfológica en carreteras son aplicaciones prácticas concretas de la tesis. / The objectives of this thesis are the identification of the hazard at intersections between ephemeral channels and roads, and the application of different rates, resulting from quantitative and qualitative assessments based on important fieldwork stored in descriptive sheets.Different drainage affecting the study area are analyzed, their functions and requirements to optimize the design type, the location and the efficiency of cross drainage works to flood flows. This serves as a starting point to learn about the dangerous road junctions to ephemeral channels depending on the level of exposure of road infrastructure and the type of road crossing.To obtain flow data has been used the unit hydrograph method (UHM) and the modified rational method (MRM) and the integration of hydraulic geometry methods and techniques of remote sensing. Additionally, a hydraulic modeling has been run and the application of empirical models for estimating the bed erosion and bedload transport.Another objective of the study is define proposals for data management about hazard focused to strategies and plans for protection of citizens. The use of web viewers by the competent authorities, integration, maintenance and management of data and the creation of an interactive atlas and hydrological and hydromorphological hazards on roads are actual practical applications of the thesis.
