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 ...

An automatic triple-ring infiltrometer was developed using a set of pre-set sensors and transducer (AP 403, AP 404, 405 406, RAP001 RAP002). The aluminum probe were graduated arranged in series to monitor the rate at which water is infiltrating into soil layer. working principle six probes with depth calibration 1.0mm, 26.7 mm, 12.4 12.7 respectively. result obtained showed strong agreement coe...

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...

Abstract Infiltration stormwater control measures (SCMs) have the potential to contribute towards mitigating effects of urbanization on downstream receiving waters. SCMs are most often successful when in‐situ saturated hydraulic conductivity ( K sat ) is well characterized. In this paper numerical solutions Richards’ equation used quantify bias seven infiltration measurement methods, removing n...
