Abstract

Abstract In this study, analysis of the flow of water in the soil environment was attempted to examine the changing patterns of per-meability coefficient, k, presented in Darcy's law depending on soil particle size and the pattern of mixed soil that main factoraffecting ground water flow in soil environment. In addition, permeability coefficient patterns depending on changes in watertemperature and concentration were measured. As a result, the permeability for the soil particle size and mixing pattern is pro-portional to the size of the particles, and it was also influenced by the porosity depending on the mixed pattern and stratification.Especially compared with the single particle, mixing different sizes samples showed a lower k than the value of smaller singleparticles. In addition, permeability of groundwater increased with increasing temperature, also permeability decreased dependingon the concentration of ions in groundwater. The results of this study were expected to use as meaningful data for the phe-nomenon reflects the characteristics of the soil to understand mobility of groundwater in soil environment.Key word : Permeability, Groundwater, Soil Particles, Darcy’s law * Received : June 18, 2012·Revised : August 3, 2012·Accepted : August 20, 2012Corresponding Author : Dong-Su Kim (E-mail : dongsu@ewha.ac.kr)Environmental Science and Engineering, Ewha Womans University, 11-1 Daehyundong, Seodaemungu, Seoul 120-750, KoreaTel : +82-2-3277-2394 / Fax : +82-2-3277-3275ⓒThe Korean Institute of Resources Recycling.
