KOSTRA-DWD
Opens the program KOSTRA-DWD 2000 or KOSTRA-DWD 2000 Dach, which you can use to determine the rainfall for the desired location. Prerequisite is a working installation of the software. The software KOSTRA-DWD is available from the Deutscher Wetterdienst.
The interface to KOSTRA is only supported for the KOSTRA 2000 version. No interface is included in other KOSTRA versions. If necessary, use XML import (+ KOSTRA XML) for versions without an interface. + KOSTRA XML
+ KOSTRA-XML
If you exported an XML-file from KOSTRA, you can load this file using the button +KOSTRA-XML and use its rainfall rates.
<Select Location> or <Select Another Location> or Selected Location
Drop-down list for location selection
Select the location whose rainfall rate you want to use. The selectable locations come from the selected rainfall rate file, which is displayed behind Source. If no rainfall rate-file has yet been loaded, do so by using the function Load/edit rainfall rate file.... The statistical rainfall rates for the location are then transferred to the corresponding fields in the rainfall table.
Alternatively, enter a location of your choosing to be saved only with this project.
Load/edit rainfall rate file...
Opens the Calculation Rainfall file dialog, where you can create, save, and load your own rainfall file.
Table Rainfall Rates for Selected Location
The fields r5,2; r5,5; r15,2; r5,30; r15,30 and r5,100 show the current rainfall rates that will be used for calculation. If a rainfall rate-file has been loaded, these fields will be filled with data from the selected file.
Alternatively, rainfall data for the respective building location or according to DWD KOSTRA can be entered manually. To do this, either select a value from the list box or enter the desired value (numerical value) directly. If you adjust the values, they will not be saved in the rainfall rate file but in the project.
Calculated rainfall rate, Open area rainfall rate, Over-five-minute-long rainfall rate
These values are the calculation basis for the dimensioning of rainwater pipes. The fields are filled using default values. You can select or enter a different value.
Consider over-five-minute-long rainfall minus reference rainfall/Consider over-five-minute-long rainfall in full
Depending on the selected method for siphonic drainage, it is automatically set here whether the over-five-minutes-long rainfall should be taken into account in full or minus reference rainfall. You can select the other option manually.
