Storage Window
| 
| 
The data sheet for the memory can be opened by double clicking on the element symbol in the system plan 30px or by right clicking -> Data sheet.
It has the two tabs Properties and Simulation Settings.
Properties
right The Properties tab of the storage element is divided into different areas (from top left to bottom right):
- internal dependencies
- levies
- limits
- master data
- sequences
- storage curves
- loss/grant (precipitation, evaporation, infiltration)
In the following, these are discussed in the order in which they are usefully processed.
Master data
The first time you create a new system element reservoir, a window with the master data of the memory appears. Later, the window can be opened by clicking the button Master data in the upper right corner of the storage tank window. Here the most important characteristics of the memory should be entered.
The terms are oriented towards dams, since the system element was originally developed as a pure dam element. For dams, the height and the content are entered for the following positions:
- Bottom (content=0)
- Flood discharge
- Crown (maximum content)
For all other memories, instead of the content at crown height, a fictitious value can be specified as maximum content, which is never exceeded in the model.
It is helpful to fill in the master data right at the beginning and to adjust all other functions to be entered in the storage element (e.g. storage characteristic curve, or function of the flood discharge) exactly to this master data. If the maximum content is changed afterwards, you can choose from two options at the bottom of the window how to proceed with the other functions of the storage element. There is the possibility to adjust the function values of all functions according to the percentage change of the maximum content. The other option is to keep the function values. In this way, all interpolation points that are larger than the new maximum content are discarded. In both cases it is important to check all functions!
Storage curve
After entering the master data, it makes sense to enter the storage characteristic curve next. To do this, activate the checkbox next to the (initially grayed out) symbol for the storage characteristic 
at the bottom left of the window. Later, the storage characteristics can be edited by clicking the icon. Deactivating the check box deletes the storage characteristic curve again.
The storage characteristic curve compares the content of the storage tank with the respective water levels and the surface. When entering the data, it is important to note that the height and content data must be consistent with the positions for the river bed, spillway and crown that have been entered in the master data sheet. The first grid point is always content: 0 | height: sole height | surface: 0. The last grid point is content: maximum content | height: crown height | surface: corresponding maximum surface.
Release
Create new release
To create a new delivery, click the button Create new delivery 
in the area Deliveries of the memory window. Afterwards a window appears, in which the class and the type of the delivery can be selected and a designation can be assigned.
The class of the delivery can be chosen between Q, adjustable delivery and K, non adjustable delivery. The following options are available for the type of levy:
| Kennung | Standardbezeichung EN | Bezeichnung DE |
|---|---|---|
| A | Release | Abgabe |
| W | Water supply | Wasserversorgung |
| R | Standard release | Regelabgabe |
| H | Spillway | Hochwasserentlastung |
| S | Flood control zone | Hochwasserschutzraum |
| M | Minimum release | Mindestabgabe |
| N | Low flow augmentation | Niedrigwasseraufhöhung |
| T | Turbine | Turbine |
| B | Industrial supply | Brauchwasser |
| U | Water transport system | Überleitung |
| D | Dynamic release | Dynamische Abgabe |
The selection of type, class and the input of the designation is mainly informative. The user himself is responsible for entering the data for delivery afterwards. The identification of the levy is made up of three digits: the first letter is determined by the selected class, the second by the selected type, followed by a unique number in the third position, which is assigned in the order in which the levy of the respective class and type is created. The charge identification determines how the simulation results are stored and how the charges can be addressed for the definition of system states. For this purpose, the delivery identifier is appended to the respective system element identifier with underscore, e.g., T100_QA1.
After the delivery has been created, a box with the respective delivery identification appears in the memory window in the area Deliveries.
Edit submission
An already created levy can be edited by double clicking on the box with the levy ID in the Levy section or by right clicking on the box -> edit. A new window opens.
Enable/disable output
To the left of the box with the delivery ID there is a checkbox that can be used to activate and deactivate the delivery. Disabled dispensers are not taken into account in the simulation.
Clear submission
A delivery can be deleted by right-clicking on the identifier to open the context menu and selecting delete.
Abläufe
Newly created memory outputs do not yet have an output from the memory. Therefore an allocation to an outlet has to be established first. If the memory element in the system plan is already connected to other system elements connected elements, these elements appear with their identifier in the Sequences area on the right side of the window. A delivery is now assigned to a schedule by connecting them via drag&drop. To do this, drag the box with the ID of the delivery with the left mouse button pressed down onto the box with the ID of the schedule. The created connection is displayed with an arrow. Similarly, an existing connection can be deleted. A run can contain several deliveries.
Limits
Create new limits
To create a new limit for an operating device, click the button Create new limit in the memory window in the Limits area. After that a window appears in which the identification of the border can be selected and a name assigned.
The following options are available for the type of limit of the operating equipment:
| Kennung | Standardbezeichung EN | Bezeichnung DE |
|---|---|---|
| G | Bottom outlet | Grundablass |
| B | Service outlet | Betriebsablass |
| A | Outlet | Auslass |
The selection of the type and the input of the designation is mainly informative and does not affect the calculation. The identification of the boundary is made up of three digits: the first letter is always "G", the second is determined by the selected type, followed by a unique number at the third position, which is assigned in the order in which the boundaries of the respective type are created.
After the limit has been created, a box with the respective identification of the limit appears in the memory window in the area Limits.
Edit limits
An already created boundary can be edited by double-clicking on the box with the identifier in the Boundaries area or by right-clicking on the identifier -> edit. A new window opens for this purpose:
Here the minimum permissible discharge through the facility can be entered. After clicking the Function button, the content discharge function can also be entered as a limit function.
Assign a boundary of release/ delete assignment
A release can be assigned to a border by drag&drop. For this purpose, the box with the identifier of the levy is dragged onto the box with the identifier of the border. The connection is displayed with an arrow. Similarly, the connection can be deleted again.
Delete Boundary
To delete a boundary, right-click on the boundary and select Delete from the context menu.
Internal dependencies
Create new internal dependency
To create a new internal dependency between two releases, connect the two releases by dragging and dropping. To do this, drag the box with the identifier of the release that is to provide the condition for the reduction onto the box with the identifier of the release that is to be reduced. The connection is represented by an arrow. One release can reduce several other releases, for this purpose several connections are created from this release.
Edit internal dependency
To edit an already created internal dependency, first select the release that should provide the condition for the reduction and then click the button Edit Int. Dependency 
. Alternatively, after right-clicking on the delivery, select -> edit internal dependency from the context menu. After that a window appears
In the window that appears, you can enter the value that the release must exceed and the storage content must fall below in order to trigger a reduction of the other releases. The entry is made as a constant value, if necessary scaled with a hydrograph, which can be selected from the corresponding drop-down lists. At the bottom of the window the arrow buttons 
can change the order in which the release are to be reduced.
The order in which the deliveries are to be reduced can also be adjusted in the window that opens when you click the Sequence button 
from the save window.
Loss/ External contribution
External contribution/ losses at the reservoir in the form of precipitation, evaporation and infiltration can be entered in the lower area of the reservoir window. For this purpose, the checkbox next to the respective symbol is activated and a new window appears. This window can also be opened later by clicking on the symbol of the loss/subsidy.
Berechnungsweise
Der Verlust-/Zuschussterm kann entweder als konstante Ganglinie (Achtung: Bezeichnung in der GUI: Funktion (Btr.Regel)) eingegeben werden oder als Zeitreihe (Achtung: Bezeichnung in der GUI: Funktion + Datei), ggf. skaliert mit einem Faktor. Unabgängig von der gewählten Berechnungsweise, wird der speichereigene Verlust/Zuschuss automatisch mit der aktuellen Speicheroberfläche skaliert.
Simulationseinstellungen
Im Reiter Simulationseinstellungen des Speicherfensters werden die Anfangsbedingungen für den Speicher festgelegt:
Der Anfangsspeicherinhalt [Tsd.m³] kann in ein Textfeld eingegeben werden. Zur Orientierung steht direkt darunter der Maximalinhalt des Speicherelements. Mit der Eingabe passt sich die Grafik mit dem Füllstand der Talsperre im mittleren Bereich des Fensters automatisch an und der Füllstand wird in Prozent ausgegeben.
Für alle bereits definierten Stoffe wird hier ebenfalls die Anfangskonzentration [mg/l] angegeben. Dazu wird der Stoff aus der Dropdown-Liste ausgewählt und in dem Textfeld daneben die Anfangskonzentration eingegeben. Wichtig ist es danach den Button Übernehmen zu klicken 
, da sonst der Eintrag beim Schließen verloren geht. Wird der Button nach der Änderung nicht geklickt, erscheint zwar noch ein Meldungsfenster, aber der Ja-Knopf ist inaktiv, d.h. es wird nicht gespeichert.
Unten im Fenster gibt es noch die Möglichkeit den Startwert für den Inhalt aus einer Zeitreihe auszulesen. Der Wert in der Zeitreihe zu Simulationsbeginn wird als Startwert für den Anfangsinhalt gesetzt. Die Auswahl der Zeitreihe aus der Zeitreihenverwaltung erfolgt über den Button Auswahl 
. Über den Button Anzeigen 
öffnet sich ein Fenster mit einer Grafik der Zeitreihe.
