Microflowmeter-tension disc infiltrometer – Part I: Measurement of the transient Infiltration Rate
Journal of Hydrology, 2012Co-Authors: David Moret-fernández, César González-cebollada, Borja LatorreAbstract:Summary The tension disc infiltrometer is a useful tool for in situ measurements of soil hydraulic characteristics in the vadose zone. Soil hydraulic properties can be estimated from an analysis of the transient section of the cumulative Infiltration curve, which is commonly measured from the water-level drop in the reservoir tower. This paper presents a new design of tension disc infiltrometer with the disc sepaRated from a Mariotte tube, the bubble tower and the water-supply reservoir, in which the full Infiltration Rate curve is measured with a microflowmeter plus Mariotte tube system (MF). This disc infiltrometer was tested in the laboratory on two 1D sand columns and two 1D and 3D 2-mm sieved loam soil columns, and in the field in three different soil-structure conditions. The cumulative Infiltration and Infiltration Rate curves recorded with the MF method were subsequently compared with the corresponding curves measured from the water-level drop in the water-reservoir tower (WLD). Although the cumulative Infiltration curves calculated with the MF method fitted well with those obtained using the WLD technique, the laboratory experiments showed that the MF system allowed more accuRate estimates of the Infiltration Rate curves. Smoothing data using a simple moving average algorithm made it possible to improve the characterization of the Infiltration Rate curves. These results were corroboRated in field experiments, in which the MF system proved to be more robust than the standard WLD procedure. These results confirm that the disc infiltrometer design proposed here can provide a solid alternative to the classical disc infiltrometer, and, as described in the second paper of this series ( Moret-Fernandez et al., 2012a ), offers an alternative for estimating the soil hydraulic properties from an analysis of the Infiltration Rate curves.

dynamic monitoring of soil bulk density and Infiltration Rate during coal mining in sandy land with different vegetation
International Journal of Coal Science & Technology, 2014Co-Authors: Yinli BiAbstract:To investigate the effects of coal mining on soil physical properties, sandy lands with three major vegetation types (Salix psammophila, Populus simonii, and Artemisia ordosica) were investigated by the ring knife method and double-ring infiltrometer. Specifically, variations in soil bulk density and water Infiltration Rate and the influences of coal mining and vegetation type on the properties during different subsidence stages were studied at the Shendong Bulianta mine. The results showed that, in the period before mining, soil bulk density occurred in the order A. ordosica > P. simonii > S. psammophila, with a negative correlation between the initial Infiltration Rate and steady Infiltration Rate being observed. In the period during mining and 3 months after mining, there were no significant differences in soil bulk density and water Infiltration Rate among vegetation types. At 1 year after mining, the soil bulk density occurred in the order A. ordosica > S. psammophila > P. simonii, having a negative correlation with the steady Infiltration Rate. The water Infiltration depths of the S. psammophila, P. simonii and A. ordosica were 50, 60, and 30 cm, respectively. The Infiltration characters were simulated by the Kostiakov equations, and the simulated and experimental results were consistent. Linear regression revealed that vegetation types and soil bulk density had significant effects on soil initial Infiltration Rate during the four study periods, and the Infiltration Rate of the period 1 year after mining was mainly influenced by the soil bulk density of the period before mining. The results indicated that vegetation types had significant effects on soil bulk density, and that the tree–shrub–grass mode was better than one single plantation for water conversation and vegetation recovery in sandy land subjected to mining.
