In jschap1/WSEw: River Geometry Package for Studying Water Surface Elevation-Width Relationships
Description
Usage
Arguments
Details
Examples
Description
Uses the transect to get the main channel from a transect potentially covering multiple channels.
Also provides other useful info, like width to banks.
Usage
1
get_main_channel(transect, return_all = FALSE)
Arguments
transect
depth values along a transect
return_all
use it to return the indices of transects where the main channel begins and ends
Details
This function is not perfect!
Sometimes the widest channel may not be the main channel.
Can we discriminate based on how deep the channel is?
With the current method, there is going to be some error
associated with misclassification of the main channel.
plot(transect[wide.ch.ind], main = "2", type= "l")
plot(transect[wide.ch.ind1], main = "1", type= "l")
summary(transect[wide.ch.ind])
summary(transect[wide.ch.ind1])
Examples

get_main_channel(transect)
