Item Análise temporal do uso e ocupação do solo da Bacia do Médio Jaguaribe - CE(2018) Castro, José Artur Borges de; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585The hydrographic region of the Middle Jaguaribe is an area of vital importance to the state of Ceará, benefiting the whole region around it with fish farming, irrigation, water transposition and, as a consequence of the dam, regulates the flow of the Jaguaribe River. Its construction began in 1995 and concluded in 2003. In recent years, there has been a reduction in precipitation, which means that reservoirs are not recharged, reducing local economic dynamics. Following this reasoning, the objective of this work is to make a temporal analysis of the use and occupation of the soil of the Jaguaribe mid basin during a period of nine years, between 2006 and 2015, using LANDSAT 5 ETM satellite images in the year 2006 and LANDSAT 8 OLI for 2015, provided by the United States Geological Survey (USGS), the images used in the process were recorded during the dry period of the region, and using GIS applications it is possible to quantify the exposed soil, vegetation, agricultural activities and urban areas , and estimating morphometric variables. The results show a visible reduction of vegetation and soil growth, caused by the reduction of the levels of the small reservoirs and by anthropic activities, and the morphometric results indicate that the basin is not conducive to flooding.
