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...

abstract infiltration is one of the most important phenomena which is affected by the soil physical and hydraulic characteristics. measurement of infiltration needs the high cost and is time consuming, therefore estimation of infiltration is necessary. also, due to variability of soil moisture, it is important to determine the appropriate model for the estimating the infiltration rate. the pres...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

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...

Use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. In this study the infiltration parameters were evaluated in real conditions of a center pivot system. For this purpose a single ring...

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 ...

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...
