The objective of this study was to investigate the spatial variability of different physical and chemical properties of soils, and their role on transport processes of chemicals to groundwater sources in a glacial till soil of central Iowa.;Measurements were made to determine the in-situ saturated hydraulic conductivity (K;Another data set was collected on nitrate-nitrogen (NO;Data on soil moisture content, NO;A deterministic simulation model was developed with an effective hydraulic conductivity parameter based on the spatial correlation length in place of an average hydraulic conductivity parameter, to simulate the major water and nitrate transport processes for predicting the NO... |
