| The new defaults will produce different results. For established models run using the 2005-05-XX builds, use <font color="blue"><tt>Defaults </tt></font> <font color="red"><tt>== </tt></font><tt> PRE 2006-06-AA</tt> to use the previous default settings. Each of the new default settings and their affects are discussed in the rows below.

| The most pronounced effect of the shallower wet/dry depths is likely to occur in areas that are still filling at the flood peak, such as behind a levee that is only just overtopped. The shallower wet/dry depths provides a greater flow depth for a longer period over the levee.

|-

| Minor influence.

|-

| Negligible influence plus improved stability. However, note the different treatment of energy losses once the bridge deck obvert/soffit is submerged if a BG or LC table is specified.

|-

| Only affects the presentation of results. Note, that Method A is no longer recommended or supported.

|-

Does not affect hydraulic calculations, however, if a Blank, B or W channel is now lowered/raised because the inverts are now used, this will affect results/stability - see note at end of Apply All Inverts).

|-

| Will affect results as ALL PARALLEL can be around 10% more “slippery” than CHANGE IN RESISTANCE. For calibrated or established models developed using build prior to Build 2006-06-AA , recommend setting to CHANGE IN RESISTANCE

|-

| Negligible effect.
