How do you find direction of flow of a river?

Answer 1

It depends on which way the contour lines bend. For example, if the bend was facing northeast then the stream flows Northeast. the bend is this if you don't understand... -_- -> )

I'm afraid your illustration is rather ambiguous. If you imagine the contour lines to trace a parenthese as you've used, the concave side would face downstream:

Flow ---> then the contour is ( --->

Or if you think of the contours tracing a capital letter U with its open end pointing North, the stream will flow North.

A better way to understand it is to study the countour lines and streams on a map, especially if of an area you know well!

Answer 2

you can determine the direction a stream flows on a contour map by seeing which way the contour lines bend.

Answer 3

If the current is not apparent, toss a stick into the river and watch which direction it floats.
