ICrossSection Interface

Flag specifying whether the Coordinates is to be applied or ´not

Base cross section. The base cross section has no location and holds data in depth, not in water level.

Gets or sets the cross section coordinates, i.e., the geographical coordinates of line that the cross section follows.

Height of the cross section

Generel info on this cross section, user specified, can be empty. In Mike11 XNS editor called cross section ID (though it does not identify the cross section)

Returns true if the CrossSection is interpolated from other cross sections

Return true if the cross section is open

Defines the location of the current cross section. The Z-coordinate is the bottom level of the cross section (unless defined by the raw data (the open cross sections)).

Maximum width of the cross section

Minimum water depth of the cross section.

If the water depth goes below this depth, it will be corrected to match this depth.

This can be negative, in case the cross section has a slot attached.

A proportionality factor that is multiplied with the resistance factor. ResistanceFactorProportionality is used by the resistance factor boundaries to adjust the resistance factor during the simulation. If not set here, its value is default: 1.0

The ResistanceFormulation that is used for this crossSection and stored in the processed data.

This may differ from the ones specified in the Formulation, which is the formulation for the raw data.

The TopoID set that this cross section belongs to. TODO: See where for details?

The maximum value of Z in the cross section.

The minimum value of Z in the cross section (bottom level)

Creates a new object that is a copy of the current instance.

Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

Returns an extrapolated CrossSection, i.e., a copy of this cross section at the new location.

Additional storage area is a volume that the mass equation takes into account, but it does not influence the momentum equation. It could be a small pond next to the river that is filled/emptied as the water level in the river raises/falss.

Return the cross sectional geometric area at the given water level.

Get the conveyance at the specified water level

Gets the Critical depth for a given discharge - [m3/s] The critical depth is the depth where the flow changes from supercritical to subcritical flow.

Gets the Critical discharge for a given water level The critical discharge is the discharge where the flow changes from supercritical to subcritical flow.

Return the cross sectional flow area at the given water level.

Get storagewidth as dA/dh from neighboring values in processed XS areas at waterLevel This is how M11 does it - ONLY USED IN M11 SCHEME WHEN COMPARING DIRECTLY WITH M11 RESULTS Only implemented in XSOpen for now

Returns the hydraulic radius for the given water level. The radius are calculated as one of : todo: check: Resistance Radius. Effective area, hydraulic radius Total area, hydraulic radius.

Get the derivate of the hydraulic radius at the given water level.

Gets the Natural depth for a given discharge [m3/s] and slope [dimensionless] The natural depth is the depth where the flow resistance and velocity balances, i.e., the Manning formula is fullfilled: Q = M*A*R^(2/3)*sqrt(I)

Resistance factor for the given water level. This will always return absolute resistance values.

Get the derivative of the resistance factor at the given water level

Returns the width from left bank to right bank at the given water level.

Return the integrated additional surface area from the bottom of the top slot to waterLevel

Initialize cross section. Calculates processed data if needed.

Ensures that the resistance fomulation is not relative. If the resistance fomulation is Mannings n it is changed to Mannings M and the data are changed accordingly if the resistance formulation is Darcy Weisbach formulation and data are changed to Chezy.

Validates that this cross sections is set up correctly.

The minimum value of Z in the cross section (bottom level) at a distance dx from the center of the cross section.

Return delh for the cross section.
