Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The given figure is indicating the local water flow direction in a watershed. The bold solid line is indicating the drainage network (distributory channels). Small arrow with numbers (azimuths) are indicating local flow direction. The azimuth (for example, azimuth value of 135 indicates SE direction; 45 indicates NE direction; 315 indicates NW direction and so on) are scattered throughout the watershed area and can be used to determine the hydrological functions. Let me know if you have any further queries.
