river class

A river object contains information on river attributes at different aggregation levels. It can represent a real river network (obtained via extract_river) or an optimal channel network (obtained via OCNet::create_OCN).

The content of a river object can be treated as a list, hence its objects and sublists can be accessed with both the $ and @ operators.

For information on the aggregation levels and on the content of a river object, see OCNet::OCNet-package.

Examples

if (FALSE) { # interactive() && traudem::can_register_taudem()
fp <- system.file("extdata/wigger.tif", package="rivnet")
r <- extract_river(outlet=c(637478,237413),
  DEM=fp)

show(r)
names(r)

# extract or replace parts of a river object
r$dimX
r@dimX
dim <- r[["dimX"]]
r$dimX <- 1
r[["dimX"]]
r[["dimX"]] <- dim

}
