「積雪等値線図」の作成方法 : 克雪むらづくり計画に関する研究-I

抄録

I would like to report on a map of equal value line of snowhight in municipalities which I have developed and found for practical application. The present report therefore aims at presenting basic data on the village planning for overcomming snow in a heavy snow area. I wish to report on a new and simpler way of drawing that map. (1) Draw a figure of Experiental Return Period Curved Line at the standard point. (2) Draw figures of Experiental Return Period Curved Line at the observation points. (3) Compere the both curves at the standard point, abstract the value of revision. Draw figures of Revised Experiental Return Period Curved Line at the observation points. (4) Abstract a equation which a linear relationship exists between snowhight and hight above sea level. Search for the each value of hight above sea level corresponding the snowhight. (5) Plot the values on a map, connect the equal values with curved line paralleled to contour. Though the data are insufficient, I used a linear relationship exists between snowhight and hight above sea level and obtained satisfactory results.
