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...

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...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract In the context of studies aiming at the estimation of effective parameters for unsaturated zone modelling, this work tackles the problem of experimental data quality, considering the large collection of data gathered at an experimental sit...

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...

Permeable pavements are considered to be one of the effective measures for LID (i.e. Low Impact Development) and SUDS Sustainable Urban Drainage System) globally. The major three types permeable (a) pervious concrete (PC), (b) previous asphalt (PA), (c) interlocked paver (PICP). performance all is satisfactory at start service life but greatly reduced if not maintained on time. Considering long...

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...
