متن کاملAutomated tension infiltrometer
An automated tension infiltrometer including a soil contacting base to which is mounted a porous plate for interfacing the infiltrometer with the soil to be analyzed. A Marriotte column is positioned in the base so that its open bottom end abuts the porous plate. A bubble tower is also positioned in the base and has a bubbling tube operatively connected between its interior and interior of the ...
متن کاملDetermining Soil Hydraulic Properties from Tension Infiltrometer Measurements: Fuzzy Regression
numerical instability can be problems. Therefore, the nonlinear least-squares regression method introduced Tension infiltrometer measurements have been used to measure by Logsdon and Jaynes (1993) has been widely used, steady-state infiltration rates at applied tensions. The measurements owing to its simplicity. They estimated saturated hycan be used to determined soil hydraulic properties thro...
متن کاملestimation of soil hydraulic parameters using double-ring infiltrometer data via inverse method
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 ...
متن کاملMacroporosity and infiltration in blanket peat: the implications of tension disc infiltrometer measurements
Little is known about the processes of infiltration and water movement in the upper layers of blanket peat. A tension infiltrometer was used to measure hydraulic conductivity in a blanket peat in the North Pennines, England. Measurements were taken from the surface down to 20 cm in depth for peat under four different vegetation covers. It was found that macropore flow is a significant pathway f...
