Abstract | Variation in yearly water content of a particular sample point in relation to the water content average of the snow course was obtained for each of several years. Percentages of the mean of each sample for each year was then calculated. These data were tabulated and plotted under 'Scale' for water content and 'Percentage of Mean' for the percentage of the mean water content. The graph gave the relation of water content of each sample to the average of mean of the course for each year. When the percentage of the mean for any sample was widely scattered, the sample was considered unreliable. Unreliable areas were examined to locate the cause. It is believed that more research will result in establishing courses of 10 to 15 reliable sampling points. H.P Boardman presents a discussion of the paper and proposes methods of analysis and graphs for several snow survey courses and detailed reasoning in the text. |
