I duno if I'm correct, but this is how I try to do:

Step 1: In addition to the graph you've done for Q 1 (using x=dist fr left bank, y=depth)

Step 2: now add on the points using x= dist fr left bank, and, y= measurement depth.

Step 3:after you've got all the points on the graph, note down the point velocity of each point. Then join the points that have similar velocity eg. 0.434,0.459,0.478 should be join together.

Step 4: Those points which have only one velocity by itself, try to draw them in isovel as well, shape resembling the rest of the isovels.

Hope this helps.No guarrantee if it's correct.
