calc_depth_prediction_error: Calculate depth prediction error

In jschap1/WSEw: River Geometry Package for Studying Water Surface Elevation-Width Relationships

Description

Calculates depth prediction error, either absolute or as a fraction of bankfull depth

Usage

calc_depth_prediction_error(pred, truth, h = NULL, type)

Arguments

pred	minimum bed elevation z0 predictions
truth	true minimum bed elevation
h	bankfull water surface elevation. For UMESC data, it is the reference WSE. Not needed for absolute error.
type	can be "absolute" or "relative" or "mersel"

Details

Option "mersel" calculates standard error relative to bankfull depth, see Mersel et al. (2013)

Examples

refWSE <- 470*0.3048 # meters, for pool 21
z0.l.error.abs <- calc_depth_prediction_error(z0.l, z0.true.ra, type = "absolute")
z0.l.error.rel <- calc_depth_prediction_error(z0.l, z0.true.ra, h = refWSE, type = "relative")
load("./Outputs/Final/p21/z0_pred.rda")
z0.true.ra <- readRDS("./Outputs/Final/p21/z0_true_ra.rds")
truth <- z0.true.ra
pred <- z0.l
z0.L.SE <- calc_depth_prediction_error(z0.l, z0.true.ra, h = refWSE, type = "mersel")
