XSPolygon Methods

Adjust the processed levels. Used to ensure that _processedLevels[0] has a certain value

Adjust the processed level specification.

Return the bottom level of the cross section at a distance dx from the center of the cross section. Throws an exception if dx is larger than half the cross section width.

Calculate processed data

Calculate the processed levels, storage areas, radii, etc, ie, fill in all ProcessedXXX properties if they are not up to date. Also called by getters for these properties if needed, so usually, this method doesn't have to be called explicitly.

Validates that this cross sections is set up correctly.

Clear any stored processed data arrays

clear section from vegetation and dead water, setting all zone info to Normal

ICloneable implementation. deep clone, including owner

Converts the modified resistance data to another formulation. Returns false if the conversion could be performed. Note: so far only few conversions are supported: - from Manningsn to ManningsM;

Converts the ProcessedResistanceFactors according to a multizone set of absolute resistance values. Each input factor is applied between each level seperator, the first factor from -infinity to the first level, the second factor from the first level to the second level, and the last factor from the last level to infinity, i.e., the levelSeperators defines where one factor takes over from the previous. The factors array must be one longer than the levelSeperators array. The relative resistance factor is taken into account also. Results are stored in the ModifiedResistanceFactors and those are used in the calculation.

Copy the values of this cross section to another cross section

Creates all processed data arrays with the given number of levels.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Get actual morphological division or top of cross section if not defined.

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, for index and fraction into the processed data.

Return the cross sectional geometric area, integrating the storage widths

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, for index and fraction into the processed data. This can be the total areas or the effective flow area hence the area does not necessarily correspond to the amount of water in the system (volume)

Return the cross sectional flow area, for index and fraction into the processed data. This can be the total areas or the effective flow area hence the area does not necessarily correspond to the amount of water in the system (volume)

Get storagewidth as dA/dh from neighboring values in processed XS areas at waterLevel.

Serves as the default hash function.

Returns the hydraulic radius for index and fraction into the processed data

Returns the hydraulic radius for index and fraction into the processed data

Get the derivate of the hydraulic radius for index and fraction into the processed data.

For a given area, find the level.

Calculates a local velocity for a given x along the cross sectional profile. The result must be divided by GetLocalVelocityFactor().

The calculation is based on a parallel canal analysis, and if integrated up, matches the total discharge through the cross section.

Calculate a local velocity factor for the provided water depth. This factor is used when calculating a transversally distributed flow velocity.

Calculates the local velocity factor for use in GetLocalVelocity(Double, Double, Double).

The method is seperated from the GetLocalVelocity(Double, Double, Double) method, since this can be an expensive method (integrating over the entire cross section), to be called once, and the result used many times by the GetLocalVelocity(Double, Double, Double) method.

Return index of a marker

Returns a sequence of markers and their indices.

For a given cross section point (at some index), return all markers on that point.

Set maximum area, maximum hydraulic radius and maximum storage width.

Get the natural depth at a given discharge and slope

Returns the resistance factor.

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

Returns the width from left bank to right bank for index and fraction into the processed data

Returns the width from left bank to right bank for index and fraction into the processed data

Gets the Type of the current instance.

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

Makes all processed data arrays point to the same arrays as in the other. (reference copy, not value copy)

Calculate processed data if needed

Get the actual processed level at the given index. Works regardless of the _equidistantLevels flag, i.e., also when ProcessedLevels are not present. Index must be between 0 and NumberOfProcessedLevels-1 otherwise it will fail or give incorrect results

Creates a shallow copy of the current Object.

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.

Get the raw processed level at the given index. Works regardless of the _equidistantLevels flag, i.e., also when ProcessedLevels are not present. Index must be between 0 and NumberOfProcessedLevels-1 otherwise it will fail or give incorrect results

if Multiply... or Convert... or similar was called earlier, reset the modified resistance factors to the original processed resistance factors

Restores any stored processed data arrays previously stored.

Store the current processed data arrays (shallow copy). If a set of original processed data already exists, the original set is kept and not overwritten.

Updating the ProcessedLevels will still update the original processed data, unless new processed data has been provided, i.e. by using CreateAllProcessedArrays(Int32) or SetAllProcessedValues(Double, Double, Double, Double, Double, Double), due to the shallow copy.

The original processed data arrays are kept when setting new processed data, using e.g. SetAllProcessedValues(Double, Double, Double, Double, Double, Double)

set all the processed data (references to the member array). All values are in SI.

Set a particular marker to a given 0-BASED index (within the list of points), or remove it (call with -1). If any other point had this marker before, it gets removed from that point. Throws IndexOutOfRangeException if list of points is empty or index is invalid.

Returns a string that represents the current object.

clears the indicated existing markers and sets them to their default x location. (LeftLeveeBank: smallest x, RightLeveeBank: largest x, LowestPoint: x with the smallest z). Doesn't do anything for Circular, Rectangular.

Update the MarkerString for all cross section points with a marker. Used by the GUI.

Update the resistance values in the Points in case the ResistanceDistribution is Uniform or Zones

Validates the data. The constraints are that the levels and the areas after sorting must be monotonically increasing.

Get the conveyance at the specified processed level
