# MainBifurcationNode

Identifies the main bifurcation node (Moussa, 2008) in a catchment.

### Calling Sequence

    ABCD = MainBifurcationNode ( handle_fdr , outlet )

### Arguments

fdr

  integer: handle on the flow direction grid to be used.

rec

  integer: ID of the outlet pixel (record number in the raster, as returned by `XY2rec`).

ABCD

  Output: vector of 4 elements containing the record numbers of outlets A, B, C, D (see Moussa, 2008).

### Description
