Snow cover analysis
The seasonal evolution of snow cover from year 2000 to 2010 is shown in Figure 6, the huge difference between the entire domain and the upper Kaligandaki basin. For entire domain the average annual snow cover is 37.83% of the total area where as this is 74.11% in zone IV which is almost double than that for the whole domain. Naturally, snow cover is more persistent in the zone IV and the snow cover pick is generally found in spring but for the entire domain and duration, winter snow cover is higher than that of in spring cover. While talking about the average snow cover percentage, it is almost 90% in zone IV where as in the zone III it is around 75% similarly in the zone II it still goes down to 44% and in zone I the maximum winter snow cover extends can go up to 5%. Similarly in the summer two zones namely zone I and zone II are almost snow free and zone III may have up to 20% snow cover area and in zone IV it above 50% all the time. This statistics suggests that the snow cover area is naturally dependent with the elevation in all seasons. The figure 6 illustrates the seasonal snow cover area in four elevation zones and figure 7 depicts the time variant snow cover area in the one decade.
