Hydrotope and Overlays

The data of Hydrotope can be imported as shape file when Creating a new project. However, it is recommended that the preparation and production of Hydrotope is done in the user interface of KalypsoHydrology. This is useful because the Hydrotope data changes over time (i.e. new land use development) and these changes may be done as a simple update. In addition to general information about the detailed Hydrotope characteristics and key reference data in the Hydrotope data is mainly intended for parameter catalogue.

Views for processing the Hydrotope data

View for processing Hydrotope (Map)

To edit the Hydrotope the following views and tables are available:

Hydrotope (Table)

A list of all Hydrotope

Hydrotope (Map)

Map of the network elements and the Hydrotops of the model area.

Sub catchments

List of sub catchments, and the parameters for Hydrotope intersection.

Land Use

List of land uses and the parameters for Hydrotope intersection.

Geology

List of available geology data and the parameters for Hydrotope intersection.

Pedology

List of available Pedology data and the parameters for Hydrotope intersection.

Overlay (DRWBM)

List of available overlays and the parameters for Hydrotope intersection

Generate Hydrotope (Map View)

Generate Hydrotope

In the map view the network elements and the data are presented for the creation of hydrotope (see FigureView of Hydrotope (Map)). The data for the creation of hydrotope includes the data of land use, pedology, geology and (optionally) overlays. The parameter sets of data must be available before you import the shape data in the model. The creation of the parameter catalogue is described in the section: Parameter Definition.

Shape File Import: The import of the data is done via the map view of the hydrotope. “Import Wizard” is described here: Data Import for creating hydrotope.

Generate Hydrotope : After importing the data, the hydrotope can be created. This is done via the function Generate hydrotopein the Outline view (see: Generate Hydrotope ).

Hydrotope (Table)

View of Hydrotope (Table)

creating the hydrotope, the data from the hydrotope are added to the table hydrotope (see Figure: View Hydrotope (Table)). The attributes of the hydrotope are summarized in the following table:

Hydrotope
Name	Sub catchment	Land Use Area	Pedology	Geology	Overlay Area
[Text]	Sub-Catchments Number	Name of Land Use	Name of Pedology	Name of Geology	Name of Overlay

Direct input of values of hydrotope

A direct input of the hydrotope values is no longer necessary in the current model. Only for editing the old projects, the direct input is still supported, if the references are not set on the input data. The direct input data are the following:

Values
Land Use Key	Soil Profile	Max. Percolationsrate [m/s]	Inflow portion to the ground water	Sealing rate factor
Existing use as the Key name, Which links to the use of the use parameters Represents the data usage collection	Soil profile as the key name	Maximum Percolation Rate into the ground water inflow from the lowest layer of the soil.	Portion of the ground water [Number(double)]**	Correction factor of the standard sealing grades the associated land use [Number (double)]

'** As default, the Max. Percolation [m / s] is set to zero. In this statement there is no limitation of the Max. Percolation.

Sub catchments (Generate Hydrotope)

View of the sub catchment

The table of the sub catchments summarizes the parameters that are involved in the hydraulic top intersection. The values are summarized in the following table and are listed in the view of the Sub catchments like in the figure View of the sub catchments.

Sub catchment (Generate Hydrotope)
Name	Description	TG-Area	Correction factor Sealing grades	Correction factor Percolations rate	Distribution factor of Ground Water
[Text]	[Text]	Number (long)	Number (double) [>0.00]	Number (double)[>0.00]	Number (double)[0-1]

Name

Sub-catchment number consisting of 4 digits.

Description

Description of the sub-catchment area, such as the names of the associated water system.

Sub-Catchment area

The surface of the sub-catchment area is determined by the program when the shape file is imported. The calculation area comes from the Hydrotops associated to the sub-catchment area.

Correction factors of the sealing rates

Correction factor of the standard sealing level. The degree of sealing the associated land uses within a part area be corrected with this factor as a whole.

Corrected Percolation rate

Correction of the maximum rate of percolation (> 0.00). This percolation is used as a maximum. As default, the Max. Percolation [m / s] is set to zero. In this statement there is no limitation of the Max. Percolation.

Distribution factor of Groundwater

Correction factor to the distribution of groundwater in shallow and deep aquifers. This factor is between 0 and 1 indicating what percentage in the deep aquifer is discharged. By default, this is set to 1, which remains 100% in the flat upper aquifer.

Land Use (Generate Hydrotops)

View of the land use

The data of land use parameters to create the hydrotope is imported during the land-use data import in the table. The data forms the basis for the intersection and creation of the hydrotope.

Land Use(Generate Hydrotope)
Name	Land Use	Corrected Sealing factor	Description
[Text]	Land use (Link)	Number(double)	[Import-Information from the Data]

Name

This is used to assign elements of the shapefile to existing network elements

Land Use

Existing use key name, which is the link to the use of parameters of the land use data collection.

Correction factor of sealing rate

Is applied to the sealing class of land use type.

Description

Description of the Import-information data.

Geology (Generate Hydrotope)

Here, only the data is listed, which provides the important hydrotope data.

View of the Geology

Geology (Generate Hydrotope)
Name	Max. Percolation rate	Groundwater section	Description
[Text]	Number (double)	Number (double)	[Import-Information from the Data]

It specifies the maximum percolation rate [mm/d] from the deepest (or lowest) layer of the soil in the groundwater section here.

Pedology (Generate Hydrotope)

View of the Pedologie

The data listed here, provides the important information for the hydrotope generation.

Pedology (Generate Hydrotope)
Name	Soil profile	Description
Description	Soil profile (Link)	[Import-Information from the Data]

The reference is made to the soil profile key during import. Prerequisite for the correct assignment is the full input of parameters for the soil before the import of the shape file.

Overlay (Hydrotope or part of Sub catchment generation)

View of the Overlay (DRWBM)

After the shape file of the overlays is imported, it can be transferred to the data in the table (see Figure: View of Overlay (DRWBM).

Overlays (Generate Hydrotope)
Name	Description	Overlay Definition
[Text]	[Text]	Reference of Overlay Definition

The name of the overlay is determined by the import. The description of the overlay can be taken from the attribute table of the shape file during import and can be edited. The networking/ linkage to the overlay definition is done during import. A precondition to import the correct file is, the previous entry of all input parameters(See: Parameter Definition of Overlays).

Creation of sub-areas from overlays and integration into the network

With the newly developed concept, new areal data objects (like quasi sub-sub-catchments) are created by the data units of the overlays. These subsidiary sub-catchments are obtained according to the information of the mother sub-catchments if no optional specified overlay records is specified by the modeler. The integration of new sub-catchments in the existing network is done via "on the fly" generated nodes. Schematically the integration of new sub-catchments is shown in the adjacent figure: Creation of sub-areas from overlays and integration into the network.
