In samzipper/streamDepletr: Estimate Streamflow Depletion Due to Groundwater Pumping

Distribute streamflow depletion between two streams in a wedge-shaped aquifer.

Description

Distribute streamflow depletion between two streams in a wedge-shaped aquifer.

Usage

apportion_wedge(angle_total, angle_well)

Arguments

angle_total	angle [radians] between the two streams.
angle_well	angle [radians] from the first (lower boundary) stream and the well.

Details

This function assumes that streams are two linear tributaries which meet at the origin. This function specifically corresponds to Equations 18 and 19 in Yeh et al. (2008).

Value

A numeric of length two with the proportion of steady-state capture fraction from the first (lower) and second (upper) streams.

Examples

apportion_wedge(angle_total = (50*pi/2), angle_well = (10*pi/2))

apportion_wedge(angle_total = (50*pi/2), angle_well = (25*pi/2))
