Figure 37. Behavior of infiltration. "F" begins and ends slightly later than
GAWSER_F. F is slightly smaller than GAWSER_F for the majority of the simulation
period except when the two peak at 45 hours and at the end of the simulation period.
The differences in timing and magnitude between F and GAWSER_F is either due to
either computational differences between Object-GAWSER and the Fortran version
of GAWSER or a lag in Object-GAWSER that occurs as liquid water is routed
through STOR before it enters F (see Fig. 18).

Figure 38. Behavior of infiltration using another initial value of TINF. The differ-
ence in magnitude between the peak of F and GAWSER_F in Figure 38 is much
greater than the difference in magnitude between the peak of F and GAWSER_F
shown in Figure 37 because F and GAWSER_F in Figure 38 were generated using a
smaller initial value of TINF (total amount of water infiltrated into the top layer of
soil). The initial value of TINF used to generate Figure 38 was 0.00001. The initial
value of TINF used to generate Figure 37 was 0.48 (the value of IMCa or adjusted
initial moisture content of the top layer of soil).
