5 Concluding Remarks

As a brief introduction of the water flow direction model, this paper discusses the
existing algorithms used in SFD and MFD model. The discussion continued fur-
ther to the concept of several existing flow direction models, especially on D8
algorithm. The limitations of the D8 algorithm stated by some water-related
