Matt's response brings up antoher question.

Therefore
knowing the angle won't tell you much about the speed of the kayak, but
a
photo's measured angle might be able tell you about the depth of the
water
(at least if the angle is greater than 38 deg 56' and you know some of
the
other parameters in the picture). <<

I imagine this angle is related to viscosity or how much molecules of a
particular substance are attracted to each other (I can't remember the
word for this, cohesion?). If I were paddling in mercurey would the
angle be more obtuse and in gasoline more acute?
