Modeling Snowmelt Runoff under Climate Change Scenarios
the number of SNOTEL stations lying within each elevation zone. There were no
SNOTEL stations that lay within the elevation range of zones 4 and 5; however, the
total area occupied by these zones was only 1.2% and 0.01% of the total basin area,
respectively, so the contribution of these zones to the overall snowmelt runoff was
negligible. The number of stations in zones 1 through 3 was roughly proportional to
the fraction of the total basin area occupied by each zone.
