Figure 15. Relationship between TEMPs and SDEP. SDEP decreases during
the entire simulation due to snowmelt and compaction. SDEP decreases most
rapidly when TEMPs is greater than zero; therefore, air temperature has a large
effect on SDEP.

Figure 16. Behavior of RHO and TRHO_I with respect to TEMPs. TRHO_I
steadily increases for the entire simulation period. RHO steadily increases ex-
cept when TEMPs drops below zero from 22 to 30 hours and when TEMPs drops
below zero again from 87 to 90 hours. This figure shows that RHO is more
sensitive than TRHO_I to changes in TEMPs because RHO significantly in-
creases twice when TEMPs drops below zero while TRHO_I steadily increases
despite the value of TEMPs.
TRHO_II is greater than TRHO_DEL for the entire simulation except between 25 and 46 hours and
after 87 hours when TEMP is below 0C. TRHO_DEL exceeds TRHO_II between 25 and 46 hours
and after 87 hours, because the value of TRHO_DEL is affected by SWC, which is affected by
refreezing of liquid water when TEMP is below 0C. TRHO_II is not as sensitive to changes in
SWC, because it is not as closely linked to SWC as TRHO_DEL.
Demonstration of conservation of mass
Mass is conserved within SWC and LWC of the Hydrology section as shown in Table 5. Table 5
