WebHydraulic redistribution enables the movement of redistribution” (Burgess et al., 1998, 2000, 2001; Hultine et moisture from the upper soil layers to deeper zones during al., 2003, 2004; Brooks et al., 2002, 2006). 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 ...

WebOne of the most challenging parameters in hillslope‐ and watershed‐scale, distributed, hydrologic models is the lateral saturated hydraulic conductivity (Ks). In this paper, we present a methodology to determine the hillslope‐scale lateral Ks above a moderately deep sloping restrictive layer in an 18 × 35 m hillslope plot using perched water level … Webconductivity) to water and II, is capillary pressure (head), a positive quantity. With this conversion, infiltration calculations are essentially insensitive to the model used to … Web4.4 Hydraulic Conductivity The hydraulic conductivity proportionality constant, K, can be conceptualized as the relative ease of fluid passage through a porous material. It has direction and magnitude and is represented as a vector; however, the first part of this discussion presents it as a scalar value.
