Influence of soil properties and environmental characteristics in water infiltration in urban areas

EnglishThis study investigated the influence of the environmental characteristics and soil properties on the soil infiltration rate in urban permeable area. The experiments were conducted at nine sampling points located in the urban perimeter of Campo Grande, capital city of Mato Grosso do Sul State, in the Brazilian Midwest. The infiltration rates were determined using a portable integrated rainfall and overland flow simulator. Each experiment was repeated three times, and a total of twenty-seven plots were collected. At the same time, environmental characteristics and soil physical properties, that may affect infiltration rate, were also evaluated. The relationship between theinfiltration rate, the environmental plot characteristics and the soil physicalproperties was verified using a linear correlation matrix portuguesEste estudo investigou a influencia das caracteristicas ambientais e daspropriedades do solo na taxa de infiltracao em areas urbanas permeaveis. Os experimentos foram realizados em nove pontos de amostragem localizados no perimetro urbano de Campo Grande, capital do estado de Mato Grosso do Sul, no Centro-Oeste do Brasil. As taxas de infiltracao foram determinadas usando um simulador de chuva portatil. Cada experimento foi repetido tres vezes, com um total de vinte e sete amostras coletadas. Aomesmo tempo, as caracteristicas ambientais e as propriedades fisicas do solo, que podem afetar a taxa de infiltracao, tambem foram avaliadas. A relacao entre a taxa de infiltracao, as caracteristicas ambientais da parcela e as propriedades fisicas do solo foram verificadas usando uma matriz de correlacao linear
