Spring melt in the Alaskan Arctic is the dominant hydrologic event of the
year, often releasing half of the annual runoff within 7 to 10 days.
In very low gradient areas of the Arctic, much of the snowmelt water is
lost as evaporation since infiltration is limited by ice-rich soils and
runoff is quite slow.

During road construction through severe problem areas over ice rich
permafrost, occasionally the frozen ground is completely removed and
replaced with a non-heaving gravel prior to construction.
