Diffusion through soil-bentonite backfill from a constructed vertical cutoff wall

Effects of Backfill Soil on Excessive Movement of MSE wall

The use of mechanically stabilized earth (MSE) retaining wall has gained popularity as an alternative of conventional cast in place concrete walls. The construction of mechanically stabilized earth wall is cost effective, requires less site preparation and technically more feasible compared to conventional concrete retaining wall. However, use of backfill with high fine content and their poor d...

Chapter 7. the Effect of Variability in Hydraulic Conductivity on Contaminant Transport through Soil-bentonite Cutoff Walls

There are applications of barrier technology where the variability in hydraulic conductivity from point to point in the barrier, in addition to the average hydraulic conductivity of the barrier, is important. Throughout this chapter, the following application will be referred to in order to demonstrate this point: use of a circumferential soil-bentonite cutoff wall to completely enclose a conta...

A Methodology to Assess the Radionuclide Migration Parameters through Bentonite-Sand Backfill in a Short Experimental Duration

Bentonite-Sand Backfill is a part of Engineered Barrier System (EBS) widely used in a Near Surface Disposal Facility (NSDF) to delay migration of radionuclides from the disposed nuclear waste in a geo environment. Laboratory migration experiments have been conducted to understand the advection/diffusion mechanisms of various radionuclides through backfill and to evaluate their migration rates i...
