Much like a flat cement surface warmed by the sun will cause a thin layer of water to rapidly evaporate I wonder how much evaporation occurs along the margin of the creek where the rocks have been heated by the summer desert sun? Small areas of the rocks along the margin would be covered and uncovered as small waves in the water move the water up and down the surface of the margin rocks. Would this cause appreciable loss of water? If it does then the matter of shade from vegetation along the creek would have to be considered
Any disturbance to flow of water that pushes drops of water or spray into the dry air would be subjected to high evaporation rates. Could evaporation cause much water loss in the short creeks of the Panamints?
Does barometric air pressure play a role in flowing springs?
