5. szám - Dr. Kovács György: A porózus kőzeg véletlen jellegű szerkezeti változásainak hatása a szennyeződés terjedésére

Dr. Kovács Gy.: A porózus közeg Hidrológiai Közlöny 1982. 5. sz. 207 must always be supplemented by determining the mag­nitude of the probable standard deviation. The relative standard deviation is lowest in the centreline of the plume. Its magnitude here is independent of the dis­tance measured from the centre of pollution and can be calculated with acceptable accuracy from the standard deviation of the size of the structural elements. Although proceeding towards the edges the relative standard deviation tends to increase and becomes increasingly uncertain to determine, the practical sig­nificance thereof is negligible owing to the steep decrease of the expected value.
