Assign a coeficients to dispatch J2000 discharge on TOPAGE segments

This function will assign a coeficients to dispatch J2000 discharge on TOPAGE segments using specific discharge hypothesis. Theses coeficients will be used in TNET_computeQ() and TNET_computeQlatSout() function.

Usage

TNETshape_computeCoefQcalc(path_segments, export_file, to_calc = c('up','down','sWS'))

Arguments

path_segments: string Path to the shapefile created by TNETshape_computeAreaDrain() with drained area and sub drained area of each segments.
export_file: string Path to the shapefile with results to create.
to_calc: vector of strings Vector with "up" to compute upstream area drain ratio, "down" to compute downstream area drain ratio and "sWS" to compute sub-watershed area ratio. By default, everything is calculated.

Value

None

Details

This function will compute the coeficients used in TNET_computeQ() and TNET_computeQlatSout() in order to dispatch J2000 discharge data from J2000 river network to Topage river network. The computation are the following

1 - For discharge dispatch

Used by TNET_computeQ()

\(RppAr\_v = \frac{\text{Area drain downstream of Topage segment}}{\text{Area drain downstream of J2000 reference segment}}\)

2 - For underground discharge

Used by TNET_computeQlatSout()

\(RppA\_BV = \frac{\text{Area of the subwatershed of Topage segment}}{\text{Area of the subwatershed of J2000 reference segment}}\)

Examples

## Run directly the function providing all info
TNETshape_computeCoefQcalc(path_segments = "path/to/segments.shp",
                           export_file = "path/to/exportFolder")
#> Error: Cannot open "path/to/segments.shp"; The file doesn't seem to exist.
