XS_areas: Calculates a mass balance of modeled channel change

In rodlammers/REMvisualizer: Visualizations for Analyzing Output from the River Erosion Model (REM)

Description

Calculates changes in cross section area and compares that to sediment inputs and outputs to determine if mass was conserved during the simulation. Note the mass balance is not accurate if meandering was simulated.

Usage

XS_areas(path = "")

Arguments

path	Path to folder with model outputs

Value

Prints results of the mass balance and a plot of volume changes of channel cross sections.

Volume sum	Sum of total channel volume change ((-) indicates net erosion, (+) indicates net aggradation)
Bed vol out	Total volume of bed material load explorted from the watershed
Bed vol in	Total volume of bed material load imported to watershed
Bank tank	Volume of failed bank material in the bank "tank" (this is material that couldn't be deposited at the bank toe but is stored in a virtual "tank" to conserve mass.)
Bank washload	Volume of eroded bank washload
Bed washload (cohesive)	Volume of eroded washload from cohesive bed erosion
Knickpoint washload	Volume of eroded washload from knickpoint erosion
Knickpoint correction	A volume correction for when a knickpoint is initially located between two cross sections
Diff	Calculated volume difference between calculated change in sediment inflow and outflow and total channel change
Percent Diff	Calculated volume difference as a percentage of Volume sum
