Five large scale lysimeters (7.3 × 3.0 × 3.0 m deep) have been constructed to collect information and data on hydrological factors which affect the movement of water through a large scale oil shale waste embankment. Soil moisture movement within the lysimeters over time is being monitored using in situ water contents obtained with a neutron probe and Time Domain Reflectometry (TDR). Data indicate that the neutron probe and TDR show approximately a 5 percent difference in measured water content in the processed and combusted oil shale waste material.
