Since the direction of flow is influenced mostly by topography, some headwaters or sources (mountains) are located to the south of the mouth or destination. In this case, the river will flow in a northerly direction.

Flow direction example When water flows west, it has a value of 16. All 8 adjacent directions at a given point can be described using the eight-direction pour point model. When running the flow direction algorithm, the resulting values range from 1, 2, 4, 8, 16, 32, 64, and 128.

The colors of the lines usually indicate similar classes of information: topographic contours (brown); lakes, streams, irrigation ditches, and other hydrographic features (blue); land grids and important roads (red); and other roads and trails, railroads, boundaries, and other cultural features (black).
