Survey of earth and sand transfer with snowy mud flow and erosion control program

Study period:1996 - 1999
Research overview:
Making it the final target to profit determination of earth and sand production quantity in the snow season and effective erosion control program, the present survey purposes to quantitatively grasp produced quantity of earth and sand caused by such snow move as snow glide and full-layer snowslide. In the fiscal 1999, we conducted measurement of slope eroded quantity with snow glide, grasp of relationship between the eroded quantity and earth quality. It became clear in consequence that the eroded quantity had a high correlation with such physical properties as density and grain size, and possibility to judge degree of the slope eroded quantity from characteristic of the earth quality was suggested.
