To open the short-term simulation/design storm window, click the icon Datei:Button_Fenster_Kurzfristprognose.PNG in the function bar of the Talsim-NG main window. Alternatively, open the system administration by right-clicking on the scenario (menu item: Short-term simulation (model rain)) and then open the short-term scenario/design storm window via the context menu.

Then, use the short-term simulation/design storm window to manage, create and edit short-term simulations/design storms.

To run the created short-term simulation, start it in the system administration via the context menu (Simulation → Start simulation).


The window consists of:

  • Menu bar (at the top)
  • Selection menu with already created short-term simulations (beneath the menu bar)
  • View section (top left)
  • Simulation section (middle left)
  • Section for load definitions (lower right corner), separated into two tabs
  • Inflow
  • Precipitation

Simulation/Design Storm Menu


Creating a New Simulation/Design Storm

By selecting the menu item New a dialog window opens, in which the name or a short description for the new short-term simulation is entered.


Copying a Simulation/Design Storm

Selecting the menu item Copy, the dialog window opens, and the name of the copy of a short-term simulation is entered. Confirming with OK copies the simulation selected in the selection menu of short-term simulations.

Saving a Simulation/Design Storm

By selecting the menu item Save, the short-term simulation is saved with the current settings. Alternatively, it can be saved using the Speichern button at the bottom left of the window.

Confirming a Simulation/Design Storm

Attention! This function is no longer supported! Leads to program crash!

Deleting a Simulation/Design Storm

Deletes the simulation selected in the selection menu.

Setting Precipitation Factors

Imports scaling factors for the model rainfall of every single catchment area from a file. The file must have the name N_Factor.txt and must be located in the same directory as the connected databases (dataBase, see also Directory Structure).

Using the Selection Menu


Use the selection menu to select a beforehand created simulation to process it further. Use the name button on the right side to change the name of the selected short-term simulation/design storm.

View Section

In the View section, there is a button Graph, with which flood waves or model rains can be displayed as a graph. Using the tab Precipitation, globally set model rains are displayed (i.e. before scaling with factors for catchment areas). Using the Inflow tab, a point source must first be selected in the point source section. Then, the flood wave which is assigned to the respective point source during the attribute definition is displayed.

The graph window has the tabs Hydrograph and xxx. The tab Hydrograph shows the graph, while xxx gives out a list of the grid point values of the simulation.

Selecting the menu item Format, it is possible to alter the graphic (settings for grid, axes, and labels).

Simulation Section

The general simulation settings, such as the start of the simulation (format: DD.MM.YYYY hh:mm), time step [min], and time steps to be simulated [-] are entered in the simulation section.

Load Definition Section

The load definition of a short-term simulation/design storm can, depending on the respective system element, be entered as inflow or precipitation in the corresponding tabs. For point sources, the load is defined as an inflow (flood wave), for catchment areas as precipitation (model rain).


The tab Inflow is divided into the two sections Settings (global) on the left side and Point Source on the right side.


In the Settings section, the global settings for the flood event are defined. From the selection menu, the flood event is selected. The flood event must already exist and thus be created beforehand. Here, the start-up periods and the peak values for all inlets can be scaled globally.

In the section Point Source, all settings for point sources can be set. To do this, a point source is selected from the list. Then, the respective flood wave for the point source is selected from the selection menu. In the lower section, individual attributes of the flood wave can also be changed for the selected point source.
