Inverse Estimation of Soil Hydraulic and Solute Transport Parameters from Transient Field Experiments: Heterogeneous Soil
While inverse parameter estimation techniques for determining key parameters affecting water flow and solute transport are becoming increasingly common in saturated and unsaturated zone studies, their application to practical problems, such as irrigation, have received relatively little attention. In this article, we used the Levenberg–Marquardt optimization algorithm in combination with the HY...
متن کاملSimultaneous estimation of soil hydraulic and solute transport parameters from transient in®ltration experiments
Estimation of soil hydraulic and solute transport parameters is important to provide input parameters for numerical models simulating transient water ̄ow and solute transport in the vadose zone. The Levenberg±Marquardt optimization algorithm in combination with the HYDRUS-1D numerical code was used to inversely estimate unsaturated soil-hydraulic and solute transport parameters from transient m...
متن کاملExtraction of model parameters for reactive solute transport
In the present study, tried to examine the reactive solute relationships for transport and degradation processes through the rockfill media. By applying the analytical solution of reactive transport, the 1st to 3rd theoretical temporal moments have been extracted then, by using two methods of curve fitting and temporal moment matching, the coefficients of dispersion and degradation have been ex...
متن کاملEff ects of Soil Hydraulic and Transport Parameter Uncertainty on Predic ons of Solute Transport in Large Lysimeters
Advanced numerical simula on models can poten ally help improve guidelines for irriga on and salinity management. Many simula on model parameters have considerable uncertainty, and ideally that uncertainty should be refl ected in model predic ons and recommenda ons. In this work, we inves gate solute transport predica on intervals that can be generated by propaga ng model parameter uncertainty ...
