prediction Initial soil water didn't start exactly same as observation

[frank0434]

Probably caused by simulation only use water from 1.4 but observation still summarise the whole profile

solution
fix observation preparation

CAUSED BY SWCON

Explanation:

1. SWC changes at the end of the day.
2. Drainage occurred during the day.
3. All water gone the first day

[frank0434]

Solution: could just adjust the DUL for these particular soils and move on.

[frank0434]

Manually edit SD10 LAYER 1 from 0.333 to 0.320 after adjusting the SWCON and DUL values based on the initial SW.

LOGIC WAS:
if DUL < SW in a particular layer, change DUL to SW.

[frank0434]

Problem solved but the DUL seems still high for the late sowing dates.
