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

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

frank0434 commented 3 years ago

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.

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