The Effect of Some Soil Characteristics on the Hydraulic Conductivity of Soil in Tekirdağ Province

Abstract

In this study, the factors that affect hydraulic conductivity of the soil and their significance was examined. As a field of study, Tekirdag province was chosen, and sample points were determined by coinciding corine belonging to this city, land use, geology and soil maps in Arcmap program. Samples were collected from 53 different points (Total 187 samples). Samples were taken from 4 different depths (0-30, 30-60, 60-90, 90-120 cm) from 0 to 120 cm and then They were analysed by physically and chemically. Hydraulic conductivity measurements were made with Constant Level Permeability device in the laboratory, and the results were figured out according to Darcy's Law. Statistical analysis of the results were made with SPSS and MSTAT-C software programs. Statistically the following results were reached: significant relations were found between hydraulic productivity and clay, bulk density at negative and 1% level; significant relations were found between hydraulic productivity and sand, specific weight and porosity at positive and 1% level; insignificant positive relations were found between hydraulic productivity and silt, organic matter; insignificant negative relations were determined between hydraulic and lime, pH, salt; and significant relations at 1% level were found in the interactions made between hydraulic productivity and land use.
