Description
When using MFD, is the drainage direction the direction of maximum flow? This isn't explicitly stated in the documentation. What if there is equal drainage in two directions?

Replying to mankoff:
Yes, for MFD drainage direction follows maximum flow. In case of equal flow in more than one direction, the first encountered is used. This could be refined by using the steepest slope in case of equal flow. However, with MFD chances are very small that several directions have equal flow.
