Water Resources Research 40. doi: … WebThe data show that hydraulic conductivity varies over a wide range. There are few other physical parameters that take on values ranging over 13 orders of magnitude. In practical terms, this wide range of values suggests that an order-of-magnitude knowledge of hydraulic conductivity can be useful. Conversely, it implies that if a third decimal ...
