Functional test of pedotransfer functions to predict water flow and solute transport with the dual-permeability model MACRO

The aims of this study were to evaluate the effects of the soil structural physical attributes on the water retention and to develop pedotransfer functions (PTFs) for the estimation

Following calibration of the model for peak runoff rate and sediment concentrations, the following scenarios were formulated to apply the model and evaluate water pollution:

The objectives of this study were: to generate pedotransfer functions to estimate soil water retention at different tensions based on easily measurable soil properties; to evaluate

Correlation coefficients considering the direct and indirect effects obtained through path analysis, between sand contents (five fractions), silt and particle density (Pd) and

the semi-physical approach; 97 % of the empirical PTFs were derived based on the MLR and polynomial of the n th order techniques, and 3 % are based on the k-NN approach; 84 % of

The analysis evaluates both direct determination methods (pressure plate - PP and water activity meter - WAM) and indirect estimation methods (pedotransfer functions - PTFs).. The

Five methods for calibration of the HS equation were evaluated: calibration using simple linear regression; calibration of the parameter “A” keeping the other parameters (“B”
