Question

Hydrology help....kinda stuck thank you for looking! note: SWE is snow water equivalent

1)calculate the snow density (g/cm^3) and cold content (j/m^2) for march 2

2)calculate the snow density (g/cm^3) and cold content (j/m^2) for march 17

3) How much energy must be added to the snowpack on each date to intiate the water output phase (j/m^2)?

date variable measured station1 2 3 4 5 march 2 snowpack depth (cm) 92 94 105 93 96 SWE (cm) 29 30 33 29 32 snow temperature (c) -6 -5 -6 -6 -6 march 17 snow pack depth (cm) 88 89 102 88 91 SWE (cm) 35 36 40 35 37 Snow temperature (c) -2 -2 -3 -2 -3

Explanation / Answer

SWE is snow water equivalent is the depth of water after melting the snow

SWE = (density of snowpack / density of water) * depth of snowpack

Density of snowpack = (SWE * density of water) / depth of snowpack

1. Snow density March2= 96 * 1/ 96

2. snow density at march 17= 36.6 / 92.5
