Build or obtain a tall tube.
Make it water tight.
Fill it with water
Drill holes at regularily spaced vertical intervals.
Measure how far the water shoots out at certain elevations. (you have to measure for a control amount of drop. Higher holes have further to drop and will give greater distances is all distances are measured on the ground.)
Graph horizontal displacement against depth of overlying water.
The graph should give you a natural log relationship.
