This item consists of the following five windows:

Overview

Shows the model elements in the map overview (see Figure Views for editing the model parameter)

Kalinin-Miljukov strand

Selection of KM strands to define model parameters.

Reservoir Strand

Selection of reservoir strands to define the model parameters.

Sub catchments

Selection of Sub-catchments to define the model parameters

Kalinin-Miljukov Strang

View of the overview of the Kalinin-Miljukov model parameters

In the Kalinin-Miljukov Strand- View (see Figure Overview of the Kalinin-Miljukov model parameters). It is also possible to specify the length of the water way (Downstream [km] and Upstream [km]).

In Feature View the details of the Kalinin - Miljukov parameters are stored. Currently 5 runoff cases for the model structure are needed. The details of the outflow cases are listed in the following table:

Channel
Parameter	Unit	Description	Data type
Inflow/ discharge	[m³/s]	Discharge. 5 different discharge cases should be specified	double
K Flow	[h]	Retention constant K of the main river (Kalinin-Miljukov)	double
n Flow	[-]	Approach in the river strand (Kalinin- Miljukov)	double
K Bank	[h]	Retention constant K of the river bank (Kalinin-Miljukov)	double
n Bank	[-]	Approach in the river strand model for the river banks (Kalinin- Miljukov	double
Distribution factor	[-]	Distribution factor of the channel-bank/ foreland or run off percentage respectively, which is discharged through the main river.	double

A wizard Calculate KM parameter opens to calculate the Kalinin Miljukov parameter.

Kalinin-Miljukov Parameter Dialogue

The Kalinin Miljukov parameter dialog is divided into two areas(see Figure Kalinin-Miljukov-Parameter Dialogue). On the left side all Kalinin - Miljukov strands of the model are displayed. For the selected string in the right panel a WSPM Result is selected, which contains input data for a KM - calculation. Over the button next to the text box of WSPM result, an existing WSPM result is selected. The present result profile stations are listed in the table and must be selected for specific KM strands. The KM – strands are entered from / to, Start [km] and End [km], this will automatically start in the selected fields. For each strand, which is activated through the selection list, the KM - parameters are calculated and included in the model by clicking on Finish.

Result of a calculation and transfer dialogue

The selected settings are applied when you click Finish. The KM - parameters are calculated and written to the selected strands. Already present parameters are overwritten. After the calculation and transfer of results a progress dialogue is displayed in which any warnings and problems are listed (see Figure Result of a calculation and transfer dialogue). Double-clicking a message opens a more detailed message.
If settings for later acquisition are stored, for example, to refresh after a recalculation WSPM the KM parameters, a file is selected on the Save button. In these settings the information is stored in XML format. The Store button can be used again later in this file. The previous settings are then restored and the parameters can be recalculated.

Reservoir Strand

View of the model parameters in Reservoir strands

In the Reservoir strand view (see Figure View of the model parameters in Reservoir strands) are maintained for reservoir strands:

Reservoir strand -Parameter
Minimum Content [m³]	Maximum content[m³]	Initial content [m³]	WVQ-relationship
double	double	double	WVQ-Diagramm [Link zum Time Series Editor]

• Minimal content [m³]: Minimum storage Content
• Maximum content [m³]: Maximum storage content
• Initial start content [m³]: Basin content at the beginning of the simulation
• WVQ-relationship: Relationship between water level [mNN] = W, volume/contents [m ³] = V and discharge [ m³/s] = Q from the reservoir strand (max. 23 value triples can be defined)see Time Series Editor

Sub Catchments
