streambed_conductance {streamDepletr}

Estimate streambed conductance.

Description

Estimate streambed conductance.

Usage

streambed_conductance(w, Kriv, briv)

Arguments

w

stream width [L]

Kriv

streambed semipervious layer hydraulic conductivity [L/T]. Reeves et al. (2009) estimate this as the vertical hydraulic conductivity of the aquifer (Kv; L/T), which is itself often estimated as 10% of the horizontal hydraulic conductivity (Kh*0.1; L/T)

briv

streambed semipervious layer thickness [L] Reeves et al. (2009) estimate this as the vertical distance from the streambed to the top of the well screen, or the length of the well screen, whichever is greater [L].

Value

A numeric of lmda, the streambed conductance term [L/T]
