HDOptions Fields

Use MU approach for mass balance on H grid point

Adding a bottom slope correction in order to get depth interpolated between H and prev/next Q point and use those to average a storage width at the H point

For closed circular and rectangular, adds a storage width derivative to the equations (d(SW)/d(h)), to lessen mass errors. Only applicable if using one iteration per time step.

Use MU approach for calculating natural and critical depth.

Value between 0 and 0.5, for lagging a structure discharge calculation, scaling between newly calculated value and value from previous time step. Set to 0 to disable (using fully new value) and set to 0.5 to weight the two equally.

This is not applicable if using more than one iteration per time step.

Use MU approach at water level boundaries, using water level at time N+½ for level at time N+1. For backward compatibility, because approach is incorrect.

Create processed data arrays for processed data derivatives.

If disabled, processed data derivatives are calculated from original data. When enabled, derivatives are smooth and more accurate.

The processed data derivatives are used to calculate high order friction factor.

M11 approach is to disable this.
