Figure 30. Behavior of the solid water content of the snowpack. SWC matches
LAG_GAWSER_SWC (the Fortran prediction of SWC lagged by one hour). The one-
hour difference between SWC and LAG_GAWSER _SWC is due to computational differ-
ences between Object-GAWSER and the Fortran version of GAWSER.

alent until roughly 40 hours when LWC exceeds LAG_GAWSER_LWC. LWC exceeds
LAG_GAWSER_LWC because LWCAP, which governs the magnitude of LWC according to eq 5,
6, and 8 is too large. LWCAP is too large because it is calculated with the value of SDEP, which is
often larger than GAWSER_DEPTH (Fig. 33). Therefore, LWC and LAG_ GAWSER_LWC con-
verge together by the end of the simulation because SDEP and GAWSER_DEPTH converge togeth-
er as shown in Figure 33.
Figure 33 shows the similarities and differences between SDEP and GAWSER_DEPTH relative
to TEMPs. SDEP and GAWSER_DEPTH are nearly identical until 23 hours into the simulation
