Web2 LOW PERMEABLE PROBLEMATIC SOILS The EK method is applicable to fine grained soils because this process takes place basically due to the presence of clay particles in the low permeable soil (that cannot readily drained), possessing specific mineralogical properties, hence electrically and chemically active. Low permeable WebEquation 4.11 tells us that in a granular soil, the permeability varies as the square of the effective void or grain size. Therefore, the 5-6 orders of magnitude range of grain sizes between boulders (>200 mm) and clay (<2 pm) leads to a 10-12 orders of magnitude variation in permeability.
Webnative soil, where it receives final treatment and disposal. The sand filter is generally built with its top just above the final grade of the surrounding area, but sometimes its side walls may be exposed, when they are built of concrete. The top of the sand filter is covered with permeable soil, generally planted with grass, to allow
