A lysimeter station for contaminated soil studies
A lysimeter station has been set up by AMRA for the study of the reactive transport of contaminants in soil at the field-scale. It consists of eight lysimeters that can operate individually and simultaneously. Each lysimeter is a steel cylinder (diameter 1.14m, height 2m) filled with an undisturbed soil monolith, whose upper surface is directly exposed to the external environmental agents. A se...
متن کاملStatistical Analysis of Leachate Characteristics in Pilot Scale Landfill Lysimeter
The objective of this study was to analyze the characteristics of leachate in pilot scale landfill lysimeter for inorganic and organic compounds as well as metal and heavy metal concentrations against their operational conditions based on statistical tool through statistical package for social science (SPSS) software. To these attempts, three pilot scale landfill lysimeter test facilities were ...
متن کاملInterannual, seasonal, and spatial patterns of meltwater and solute fluxes in a seasonal snowpack
Meltwater discharge and electrical conductivity were measured in eight 1 3 1 m lysimeters, and snow accumulation and electrical conductivity of melted samples were measured in snow pits during four snowmelt seasons at Mammoth Mountain, California. The peak snow-water equivalent ranged from 0.57 to 2.92 m over the four melt seasons. Lysimeter discharges ranged from 20% to 205% of the mean flow; ...
متن کاملA Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
