lynds_two: Variable Shields number method to calculate paleoslope from...

In ericbarefoot/barefootr: A Package of Things I Find Useful

Description

lynds_two calculates the slope of an ancient river, provided you know the flow depth, the grain size of the bed material, and make some assumptions about shear stress in the river. The important part here is that the function implements a different shields number depending on whether the bed material is fine or coarse. Implemented from Lynds et al. (2014)

Usage

lynds_two(D, H, ws_mode = "simple", rhos = 2650, rhof = 1000)

Arguments

D	The median grain size of bedload sediments in meters.
H	The paleoflow depth in meters.
ws_mode	Allows you to choose one of two different methods for calculating the settling velocity of the bedload particles. 'simple' ignores the Corey Shape Factor and the Powers Index. See documentation for settle for more information. For now, this feature is disabled.
rhos	The density of the sediment in kg/m^3
rhof	The density of the fluid in kg/m^3

Value

Returns a single dimensionless number giving the slope.
