bed_stability: Analyze bed stability

Description Usage Arguments

Description

bed_stability is a function that takes the grain size distribution data output from simulate_gsd, and an estimate of the mean boundary shear stress to estimate the fraction of the bed that is stable, accounting for partial mobility for stresses between 1 and 2 times the critical value. Estimates of the stable proportion in each size class is added to the data frame,as are estimates of the CDF. The total areal fraction of the bed that is stable can be estimated by summing the variable p.stab in the output dataframe.

Usage

1
bed_stability(gsd, stress, TC50 = 0.036, Map = F)

Arguments

gsd

data frame containing GSD information (as per simulate_gsd)

stress

estimated mean boundary shear stress acting on the bed (Pa)

TC50

(optional) critical dimensionlessstress for D50 (default is 0.045)

Map

(optional) LOGICAL, when TRUE, the distributions are graphed
