This is the noun stream with a point of light at the east cardinal point, and points of darkness at each of the other cardinal points. Hence this symbol makes specific reference to a waterway located to the east.

Comments:

There is only one extant example of this Indus sign.

 

Mahadevan was quite right to assume that tablet H-325 was intended to be used to create an impression. Otherwise, the stream would have the wrong orientation.

Note the alignment, in Mahadevan's sign number 1162, of the point of light at east with the left-hand side of the point of darkness at north. The position was chosen to avoid confusion with the symbol for dusk.
