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