r.richdem.flowaccumulation

Calculates flow accumulation via one of a variety of methods.

Command linePython (grass.script)

r.richdem.flowaccumulation input=name [weights=name] method=string [exponent=float] output=name [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

r.richdem.flowaccumulation input=name method=string output=name

grass.script.run_command("r.richdem.flowaccumulation", input, weights=None, method, exponent=None, output, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.richdem.flowaccumulation", input="name", method="string", output="name")
