WebThe characteristic length-scale for a channel of width w and depth h is the hydraulic radius, Rh = wh/P, where P is the wetted perimeter. For an open channel P = (2h + w) and for a closed conduit P = 2(h+w). As a general rule, open channel flow is laminar if the Reynolds number defined by the hydraulic radius, Re = URh/ν is less than 500. As the WebAquifer hydraulic conductivity (A) is the measure of the rate of flow of water in the aquifer. By definition, aquifer hydraulic conductivity is the ability of the aquifer to transmit water under the effect of a hydraulic gradient (Lobo Ferreira et al., 2005).
