The investigated area (Fig 1) in the central part of the Netherlands contains a polder area with a soil of clay and peat and adjacent a sandy glacial ridge. The polders lie between +1.0 and -3.5 above mean sea level (a.m.s.l.).
At that depth the local soil was a form of organic debris plus mud (Peat) which was very weak and porous.
