The Continental Divide (in North America) marks the direction (towards the Pacific or Atlantic and Gulf of Mexico) rivers flow.
a line connecting the waterfalls of nearly parallel rivers that marks a drop in land level

Fall Line
The symbol for a creek on a map is typically a blue line with lines intersecting it at right angles indicating the direction of flow. It is often labeled with the word "Creek" or a thin blue line with arrows showing the flow direction.
It has no 'purpose' it is a natural occurring division. The continental divide is a line that runs down through the Rocky Mountains and on the west side of the line rivers and streams flow down toward the Pacific Ocean and on the east side of the line rivers and streams flow towards the Atlantic Ocean.
It is known as the Continental Divide.
Part of the border of Queensland and New South Wales is formed by the Macintyre and Dumaresq Rivers, Rivers do not flow in a straight line.
The imaginary line that separates river systems is called a "watershed" or "drainage divide." This line determines the direction in which water flows, with rivers on one side draining into one body of water and rivers on the other side draining into another. Watersheds can vary in size and can be found at various geographical scales.
The type we used to use on the job, had filter material inside of it which would flow down the suction line if you reversed it. It was made to only filter in the specified flow direction.
To construct a flow line map, first identify the locations and connections between them. Then, draw lines representing the flow or movement between these locations, with line thickness or color intensity varying based on the volume or importance of the flow. Include arrows to indicate direction if needed for clarity. Lastly, choose a clear and concise layout to effectively communicate the flow patterns.
The Prime Meridian marks the zero degree line of longitude. The Equator marks the line for zero degrees latitude.
Most rivers in Georgia originate in the Blue Ridge Mountains in the northern part of the state. These rivers flow southward through the Piedmont region and eventually reach the Fall Line before draining into the Coastal Plain.
