The testing was performed in support of the problem of hydrogen gas retention and release encountered in the doubleshell tanks (DSTs) at the Hanford Site near Richland, Washington. Wastes from single-shell tanks (SSTs) are being transferred to double-shell tanks (DSTs) for safety reasons (some SSTs are leaking or are in danger of leaking), but the available DST space is limited. The current System Plan for the Hanford Tank Farms (Rev. 4, Certa and Wells 2009) uses relaxed buoyant displacement gas release event (BDGRE) controls for deep sludge (i.e., high-level waste [HLW]) tanks, which allows the tank farms to use more storage space in some of the DSTs. The relaxed BDGRE controls are based on preliminary analysis of a gas release model from van Kessel and van Kesteren (2002) . Applying the van Kessel and van Kesteren model requires parametric information for the sediment, including the lateral earth pressure at rest and shear modulus. v
