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...

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...

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...

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...

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...

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...
