Get and set the list of coordinates of the catchment

A overall data interface for cathcment data, containing data properties that are common for all catchments.

This interface contains data and parameters for setting up a catchment model, and represents as such only setup data. Computational variables and methods are not included in this interface. It can be used to explore data and parameters required when setting up the catchment model.

Get and set the central point of the catchment

A set of check points in time that must be hit by the catchments.

Current time of catchment

Effective area. The effective area is the area that collects water. Can be smaller than total area, eg for Linear Reservoir or when LIDs are present.

Time step used in the simulation, it may change. It is set initially in Prepare to TimeStep, and can be updated by individual catchment models when required, i.e. it may differ from TimeStep.

Return the end time of the catchment simulation. This is set during prepare, and the catchment must make sure not to run beyond this time.

Maximum runoff flow

Minimum runoff flow

Minimum time the catchment should be able to provide values. The catchment will cache or recalculate values from MinTime to EndTime. MinTime must be updated ("dragged behind" time of calculation) from the caller to allow the catchment to discard cached values.

Method that adds a new catchment into the list of subcathcment, the factor correspond to the contributing area of the subcatchment compared to the entire area of the combined catchment

Apply a boundary to this catchment

Apply a boundary to this catchment

Apply a boundary to this catchment

Apply boundary to LID's in catchment

Apply boundary to LID's in catchment

Apply boundary to LID's in catchment

Return true if boundaries of the specified type are additive; the contributions of two discharge boundaries add up, while two temperature boundaries do not.

Calculate statistics.

Called at end of each time step, by PerformTimeStep

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

Destructor

Finalizes the time step for the catchment.

Serves as the default hash function.

Get the type of boundary required by this catchment

Gets the Type of the current instance.

Get or create a RRYearlyStat object for the specified year.

Initialize Rainfall Runoff model. Sets up static data.

Initialize Rainfall Runoff model. Sets up static data.

Initializes the cathcment plugins.

Creates a shallow copy of the current Object.

List of data types that is offered and can be used in GetValue

This procedure forwards the calculation with one time step.

Prepare Rainfall Runoff model. Sets up dynamic data so that the model is ready for first time step.

Prepares the catchment for the time step.

Prepares the cathcment plugins.

Prepare boundary source.

Prepare state for new simulation.

Write current state of plugins

Reset the catchment and set the current time.

Remove boundaries applied in previous runs

If state has been updated from outside, call this method to recalculate state dependent parameters.

This procedure forwards the calculation with one time step.

List of data types that is offered and can be used in GetValue

Return the time of next update. Used for PostTimeStepEvent event in Catchments. If a catchment uses variable timesteps, then this function must be overridden!!

Get value getter for the specified data quantity

Returns a string that represents the current object.

This routine stores the calculated variables in variables ready for export. The values in these state variable corresponds to the values written to the result file. All discharge variables are subject to a unit conversion. During the calculation discharges are calculated using the unit mm/hour and must therefor be converted into m3/s.

Trigger the PostTimeStepEvent, called at end of a time step.

The type of catchment: NAM, Urban A etc

Update internal state of catchment to time Time()

Updates check point time.

Updates the routing for the catchment.

Updates the storage for the catchment.

Update time, setting _timeNew to _timeOld + _effectiveTimeStep. This method will assue that _timeNew does not go beyond _endTime, by modifying _effectiveTimeStep. Before calling UpdateTime, be sure that _effectiveTimeStep is set.

Updates the present time if it is greater than the check point time.

Validate that the catchment is set up correctly

Validate all LIDs in catchment

Get value setter for the specified data quantity

Flag specifying whether the AreaFactor of a sub catchment is an area (in m^2) or a relative scaling factor.

When true, the AreaFactor is interpreted as the area of the sub catchment within the combined catchment. The discharge of the sub catchment will be scaled with the area of the sub catchment to get discharge per area, and then multiplied with the area stored in the AreaFactor.

When false, the AreaFactor is interpreted as a scaling factor of the discharge from each of the sub catchment. A value of one means that the entire discharge from the sub catchment is used in the combined catchment.

Subcatchment by names. The dictionary contains the name of the subcatchment and a contributing area factor, which is the fraction of the total area that the subcatchment runoff contributes to this combined catchment.
