O Riacho Jacaré é um afluente do Rio São Francisco, está localizado em sua margem direita e apresenta grande relevância para a região Norte do Estado de Sergipe. A Sub-Bacia do Riacho Jacaré ao longo dos anos vem sofrendo graves processos de degradação ambiental, devido principalmente à má utilização do solo e dos recursos hídricos. Esse processo originou-se devido principalmente à falta de planejamento relacionado à utilização do uso e ocupação do solo na região. O presente trabalho tem como objetivo fornecer os parâmetros fisiográficos da Sub-Bacia do Riacho Jacaré, a fim de, favorecer práticas futuras relacionadas ao uso e ocupação do solo e da água, baseado em um planejamento ambiental adequado referente à conservação dos recursos naturais presentes. Os resultados demonstram que a sub-bacia, está sujeita parcialmente a processos de enchentes devido a sua forma aos fatores relacionados com o coeficiente de compacidade de 1,43 e ao fator forma de 0,47.
Palavras-chave: Planejamento ambiental, geoprocessamento, enchentes.
ABSTRACT
The Riacho Jacaré is a tributary of the Rio Sao Francisco, is located in the right margin and are highly relevant to the region north of the state of Sergipe. Sub-Basin of Riacho Jacaré over the years has been suffering severe environmental degradation processes, mainly due to poor land use and water resources. This paper aims to provide the physiographic parameters of the Sub-Basin of Riacho Jacaré in order to encourage practices related to the use and occupation of land and water, based on an adequate environmental planning on the conservation of natural resources present. The results show that the Sub-Basin, is subject to partial flooding processes due to their form factors related to the compactness coefficient of 1.43 and the shape factor of 0.47.
Keywords: Environmental planning, GIS, flood.
