in this study, hydrus2d/3d software was used to estimate the hydraulic parameters of van genuchten-mualem model via inverse modeling using double-ring infiltrometers data in 3 different soil textures. nine scenarios of inverse modeling (divided in three groups) were considered with different number (5, 4 and 3) of fitted hydraulic parameters for optimization. in the first group, simulation was ...

Calculating water storage capacity can estimate how much rainwater infiltrates the ground. The soil infiltration and permeability test capacity. This study is to evaluate into soil. Research in Rawadanau, Serang Regency, has been conducted on relatively undisturbed land mixed agriculture at quaternary volcanic. (f) was measured using double-ring infiltrometer, (k) laboratory a permeameter. resu...

Developing correlations between various soil parameters are considered the major challenge to diminish time and cost associated with field measurements. Soil hydraulic and physical properties were extensively characterized using tension disc infiltrometer and soil sampling in a silty clay agricultural field in Kalaat El-Andalous, Tunisia. Tension disc infiltrometer experiments were conducted at...
