Deposited snow in the early stage of melting season has a complicated structures, with many different kinds of snow layers and ice-sheets. An ice-sheet in the snow layer acts as an impermeable layer for the downward moving free water and creates a water bearing layer on it. Horizontal movement of water in this water bearing layer is examined in this report.
In this experiment, horizontal movement of water is measured by using colored water. The relation between velocity of water and horizontal angle of snow layer is represented in Fig. 2, in which the velocity increases in proportion to the horizontal angle of snow layer. Large difference exists between lines A-B and C-D, which may be caused by the difference in texture of snow. Structures of the deposited snow at the time of these experiments are shown in Fig. 1.
For the comparison of this result, velocity of vertical seepage is obtained in Fig. 3. Horizontal movement of melted water in the snow layer is considered as an important factor of runoff in a mountainous region from the stand point of snow hydrology.
