Show 4571 Freeman- D 2590 San Juan? A There is great deal more sand and silt below the San Juan, because that river brings in a great amount of it. Q Did you encounter any sand waves either up or down the river? A there is an understanding of the term sand wave. Has that been defined by the court? BY THE SPECIAL MASTER: Q What is your definition on of it? Describe what you call a sand wave. A Perhaps I can explain it by stating what I believe to be the reason for it. Q No, state first what you tern a sand wave. A A sand wave is a wave very much sharper than the ordinary undulation of the surface, due to the fact the water has a very much higher sand and silt content than under normal conditions; possibly at times this is as great as fifteen to twenty per cent by weight, giving an action very different from that of clear, flowing water. Q You stated you had seen them. A There were evidences of sand wave condition the morning of the heavy flood above Rainbow creek, not nearly as heavy a sand wave as one would see on the San Juan or as I have seen on the lower river, below the Grand canyon. |
