Sub-base surfaces should be close-textured so as to prevent downward migration of the laying sand.

Sharp downward migrations may accelerate banks’ loan loss provisions, raise levels of risk weighted assets, and put additional pressure on capital ratios.

Total fish density estimates increased during upward migration and decreased during downward migration; this may be the result of differences in target strength caused by both reduced swimbladder volume and positive tilt while in deep waters.

The conditions that favor the downward migration of water from thawed to frozen ground are examined in terms of thermally induced hydraulic gradients, hydraulic conductivity, content of unfrozen pore water, temperature gradients, ice content, and gravity.

However, the change in the WARF does not fully account for the extent of downward migration since the last review because the WARF calculation in Davis Square III includes defaulted securities at its recovery amount, rather than at par.
