Water exclusion from tunnel cavities in the saturated capillary fringe [PDF]
, 2004 The problem of water flow around a tunnel cavity located in the saturated capillary fringe on top of a very permeable, freely-draining substratum is considered for the critical non-leakage condition when there is uniform vertical downward flow through
