Description

Streamflow depletion with fully-penetrating stream and no streambed.

Usage

1
glover(t, d, S, Tr)

Arguments

t

times you want output for [T]

d

distance from well to stream [L]

S

aquifer storage coefficient (specific yield if unconfined; storativity if confined)

Tr

aquifer transmissivity [L2/T]

Details

This function is described in Glover & Balmer (1954) based on work by Theis (1941). It contains numerous assumptions:

Value

A numeric of Qf, streamflow depletion as fraction of pumping rate [-]. If the pumping rate of the well (Qw; [L3/T]) is known, you can calculate volumetric streamflow depletion [L3/T] as Qf*Qw
