The influence of soil hydraulic property estimation on the predictive accuracy of solute transport modeling
MetadataShow full item record
Because of the complexity of processes governing water and chemical movement in the unsaturated zone, numerical models will necessarily play a key role in predicting the fate and transport of chemicals. If models are to fulfill their role as a tool in managing agrichemicals, then clearly models need to be tested for sensitivity to the method used to measure the soil hydraulic properties used in the model. The objectives of this study were to compare hydraulic parameter estimates obtained using alternative methods and to evaluate the effect of the parameter estimation method on the predictive ...
