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 ...

abstract determining saturated hydraulic conductivity (ks) is one of the important soil characteristics that its estimation is important in soil and water studies. there are several methods for estimating ks in unsaturated conditions. these methods include the inversed-auger-hole method, the double-ring infiltrometer and the single-ring pressure infiltrometer. the measurement of ks by these met...

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...

analyses illustrated that the spatial structure estimate obtained from measurement scale SLIla was inconsistent with that obtained from measurement scale t+. Thus, we conclude that the infiltrometer instrument fundamentally alters the infiltration process in such a way that measurements are only meaningful in a relative sense. Steady-state infiltration rates were measured at three instrument sc...

abstract disc infiltrometer is one of those devices that used in recent years in measurement of hydraulic conductivity of entire soil. in order to analyze the data taken by disc infiltrometer a variety of methods based on wooding’s base analyze have been introduced. the objective of this study was to compare the performances of ankeny and weir methods for predicting soil hydraulic properties us...

Pengujian infiltrasi yang dilakukan di daerah pengembangan permukiman dengan non Kecamatan Kuranji, Kota Padang, bertujuan untuk mengetahui berapa perbandingan nilai laju terdapat pada sudah dijadikan sebelum Padang. Metode digunakan penelitian ini adalah observasi dan pengumpulan data diambil langsung lapangan berupa uji belum menggunakan double ring infiltrometer. Prinsip pengujian mengamati ...

The steady infiltration rate of soil profiles is commonly determined for irrigation and conservation planning, but the divergence methods reduces reliability measurements. In this study, measured with a double ring infiltrometer (isr-dri) in different layers profile was compared between vertical saturated flow estimated by Richards equation (isr-hy). measurements isr-dri at top A, E, Bt horizon...

Infiltration plays an essential role in increasing the soil water content as a part of hydrological cycle. affects surface runoff and conservation. It also determines sustainability groundwater system. Heavy rain intensity exceeding infiltration capacity will result runoff, excessive cause erosion. This study aims to investigate suitable rate model Mediterranean clay textured with various condi...
