The most common test is a double-ring infiltrometer test where a double cylinder is embedded into the native soil and both the inner and outer cylinders are filled with water. ...
In addition, permeability tests were undertaken in all car parks using the ‘Laboratorio Caminos Santander’ permeameter and the Cantabrian Portable Infiltrometer. All results are presented together with the influence of surface and sub-base materials on water quality indicators using bivariate correlation statistical analysis at a confidence level of 95%. ...
This paper studies the infiltration behaviour of ICBP during their operational life in a car park using an improved version of the Cantabrian Fixed (CF) Infiltrometer. This laboratory device simulates direct rainfall and runoff from adjacent impervious areas over an ICBPs surface of 0.25 m2 for different slopes (0, 3, 5, 7 and 10%) and three scenarios of clogging (surface ...
Saturated (Ks) and unsaturated (K30) conductivities were measured in situ on 120 soil profiles using double ring and tension infiltrometers methods. Differences between Ks and K30 in conjunction with Poiseuille's law and the capillary rise equation were used to calculate WCM. ...
To assess the effect of compost application on the near-saturated soil hydraulic conductivity, infiltration rates were measured using a tension disc infiltrometer at three water pressure potentials –0.6, –0.2, and –0.05 kPa in the various zones of the soil profile. ...
Test methods which meet these requirements include large single-ring infiltrometers, sealed double-ring infiltrometers, and collection lysimeters. The main drawback in the use of collection lysimeters is that it can take months to obtain steady-state hydraulic conductivity values. Sealed double-ring infiltrometers are practical to use and have ...
This paper describes the use of single ring infiltrometers for evaluating the hydraulic conductivity of compacted soil liners. Procedures are presented for installation and monitoring of infiltrometers in the field. Results of hydraulic conductivity estimated from infiltrometer tests on six laboratory model liners are presented and compared with ...
