“…Successful studies involving contaminant transport have been conducted using both loose soil (Corwin, 2000;Corwin and LeMert, 1994) and intact monoliths (Vink et al, 1997). The nature of the contaminated site is such that foundations and rubble are found relatively near the surface over the majority of the lead works hence it was not feasible to extract an intact soil monolith.…”

“…Several solutions exist but all have their drawbacks. Corwin and LeMert (1994) used annular rings partially embedded in the soil to redirect water back into the main body, however additional stresses may be applied due to the rigid structure of the rings. Cameron et al (1992) purposefully created a space between wall and soil that was injected with liquid petrolatum (petrolatum jelly), a product used most notably in cosmetic creams, rust proofing compounds and mould release agents.…”

“…With this in view, researchers have developed column tests (Kookana et al, 1993;Phillips et al, 1995;Plummer et al, 2004;Porro and Wierenga, 1993) and lysimetric studies (Haines et al, 1982;Bowman et al, 1994;Poletika et al, 1995;Corwin and LeMert, 1994;Derby et al, 2002) for modelling and predicting long term behaviour of the contaminant transport in soils. Based on the obtained results, mathematical and numerical models have been developed and their validity has been checked (Yang, 1986(Yang, , 1988Rowe and Sawicki, 1992;Smiles et al, 1995;Knight, 1996).…”

To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also Lysimetric studies for modelling radioactive contaminant transport in soils 319 have used inactive salts as model contaminants. Hence, in order to model transport of radioactive contaminants, in situ lysimetric studies were conducted at a waste disposal site and efforts were made to predict long-term transportation of these contaminants by employing VS2DT software. Results obtained have been critically examined vis-à-vis those obtained from soil coring experiments.

“…Researchers have also developed different types of lysimeters, such as: (a) collection basin lysimeters, which are found to be quite useful to detect leakage from a compacted clay liner and to measure the field hydraulic conductivity (Gordon et al 1989), (b) zerotension lysimeters (Jamison and Fox 1992;Thompson and Scharf 1994), which is used to sample pore solution that moves through the soil under gravity, (c) tension lysimeters (Brye et al 1999), which collect different portion of the soil pore solution, (d) weighing lysimeters (Sayler et al 1984;Dugas et al 1990;Corwin and LeMert 1994), which are employed for vegetative water use. However, most of these lysimeters deal with remolding of the soil and hence do not replicate real life material and the boundary conditions such as fabric structure, capillary fringe, density and water content, geo-hydrological changes occurring in the soil mass, microbial activity, etc.…”

Application of In-situ Lysimetric Studies for Determining Soil Hydraulic Conductivity

et al. 2009

Several techniques such as laboratory column studies, under normal and accelerated gravity environments, numerical modeling and pedo-transfer functions have been employed by previous researchers to determine hydraulic conductivity of soils. However, these methods suffer with several limitations, particularly, as far as regeneration of in-situ soil conditions and boundary conditions, in an exceptionally small model, are concerned. Under these circumstances, insitu lysimeters are found to be quite useful for conducting the investigations to obtain hydraulic conductivity of fully saturated or partially saturated soils. These lysimeters can easily be installed in the soil mass, without disturbing its state, and are large enough to exhibit representative soil mass that exist at the site. With this in view, an attempt was made in this study to determine hydraulic conductivity of the soil mass beneath a waste disposal site in India by installing a lysimeter. Details of the instrumentation are presented in this paper along with the methodology to determine hydraulic conductivity of the soil mass.
