This pane is on the MODFLOW Features tab of the Object Properties dialog box.
When water supply does not meet demand the EFFICIENCY (OFE) can improve to 1.0 or remain the same.
EFFICIENCY_IMPROVEMENT is a flag to indicate if efficiency improvement is allowed.
False - Efficiency remains the same, crop transpiration reduced due to supply shortfall
True - Efficiency improves until it reaches 1.0, then crop transpiration reduced
If not specified, EFFICIENCY_IMPROVEMENT is automatically set to False, so OFE is held constant based on user input.
