This paper describes the design, calibration and testing processes of a new device named Automated Laboratory Infiltrometer (ALI). It allows to determinate in laboratory, under controlled conditions the saturated hydraulic conductivity (Ks) of altered or unaltered soil samples which is a key parameter to understand the movement of water through a porous medium. The ALI combines the advantages of three different approaches: measures vertical infiltration rates in a soil column, measures the actual volumes of vertically drained water through the soil column, and finally, uses heat as a natural tracer to determinate water flux rates through the porous medium; all those parameters are used to determinate Ks. The ALI was developed using the popular Arduino microcontroller board and commercially available sensors that give the whole system a low cost. Data from the ALI are recorded in a microSD memory so they can be easily read from any spreadsheet software helping to reduce time consuming and avoiding reading errors. The performance of this device was evaluated by comparing the water flow rates determined by the three approaches for which is designed; an excellent correlation among them was observed (worst correlation: R2 = 0.9826 and r-RSME = 0.94%).

In this work the development of a continuous monitoring system for the hydraulic conductivity is presented. The system uses the measurement of temperatures in geological materials at different depths to calculate the water flux rates by using analytical solutions for the Stallman's heat and fluid transport equation. Data from sensors are filtered and phase and amplitude information is extracted by using Digital Signal Processing techniques, such as DHR inside MATLAB environment. A column test was developed to evaluate the system performance and its results were compared against real infiltration data. Initial result shows a good performance (r-RSME = 0.08). After improvements, the system could be installed in the field to monitor water flux rates and hydraulic conductivity in intermittent rivers and areas considered as a recharge zones to study and quantify infiltration volumes.
