A state variable for the storage of water. More...
Inheritance diagram for WaterStorage: Collaboration diagram for WaterStorage:A state variable for the storage of water.
A class for the storage of water. The state is the volume of water stored in \(m^3\) The derivative function is given by:
\begin{eqnarray*} \frac{dV}{dt}&=&\sum_{f=1}^{F} q_f \\ F&=& \mbox{Number of fluxes in water storage} \\ q_f&=& \mbox{Water flux in } \frac{m^3}{day} \\ \end{eqnarray*}

Public Attributes | |
| std::string | Name |
| The Name of this node. | |
| const int | node_id |
| The Id of the node. | |
| cmf::geometry::point | position |
| The spatial position of the node. | |
Protected Member Functions | |
| void | MarkStateChangeHandled () |
| Sets the updated flag (m_StateIsNew) to false. | |
| bool | StateIsChanged () |
| Returns if the state was currently updated. | |
Overrides of flux_node | |
| virtual bool | RecalcFluxes (cmf::math::Time t) |
| Pure flux_nodes do not influence fluxes, therefore no recalculation of fluxes is required by flux_node. | |
| virtual double | is_empty () const |
| Returns true if the node has no water. | |
| WaterStorage | ( | cmf::project & | project, |
| const std::string & | Name = "", | ||
| double | InitialState = 0, | ||
| double | scale = 1 ) |
creates a water storage (abstract class)
| project | The project the waterstorage belongs to |
| Name | Name of the water storage |
| InitialState | Initial water content in m3 |
| scale | A kind of "standard size" in m3 of the water storage to scale tolerances, default 1m3 |
|
overridevirtual |
Returns the water potential of the node in m waterhead.
The base class water storage always returns the height of the location
Reimplemented from flux_node.
|
virtual |
Pure flux_nodes do not influence fluxes, therefore no recalculation of fluxes is required by flux_node.
WaterStorage overrides this, since state changes require an update of the fluxes
Reimplemented from flux_node.
|
inherited |
Returns the sum of all fluxes (positive and negative) at time t.
Single fluxes can be excluded from the calculation
| t | Time of the query |
| Without | A flux_connection that is excluded from the waterbalance (e.g. to prevent closed circuits) |
