Soil Profile

A distinction is made between the soil type (horizons) and soil types ( Profile See Preparation of soil data ).

Views to the editing of the soil

Following three views are available here:

Horizons

The term Horizons stands for Soil horizons. The (ground) horizon may refer to an area in the floor with almost the same properties, which differs from the above or below following (floor) horizon. The sum of the stacked horizons of a soil make the Soil profile.

Profile

The sum of the layered different soil horizons is known as soil profile.

Feature View

Editing window for the item properties.

Procedure

In the subsection of the menu select Parameter Definition, and then select theSoil( See Figure View of entering the horizons)

Horizons

View of entering the horizons

First, the used soil horizons and their parameters is collected. A database of KalypsoHydrology is available, which must be supplemented if necessary. Add the soil types and proceed as follows:

1. Select Horizons- Database

2. With the button Feature New insert a new soil horizon in the tables (See Figure Display at entering the horizons)

3. In the Feature View enter the Name, Welting point, Field Capacity, Maximum pore volume, Kf-value and Initial soil moisture (See Table Soil Horizon Lists)

Soil Horizon lists
Parameter	Unit	Value Type	Significance	Data type
Wilting point	[mm/dm]	[ - ]	Wilting point	Number (double)
Field Capacity	[mm/dm]	[ - ]	Field Capacity	Number (double)
Maximum Pore volume	[mm/dm]	[ - ]	Maximum Pore volume	Number (double)
kf-Value	[mm/d]	[ - ]	Water Permeability Number	Number (double)
Initial soil Moisture	[-]	[0-1]	Initial soil moisture content in relation to the maximum soil moisture .	Number(double)

4. Using the button Delete Features can delete Soil Horizon-Features.

Profile

View of insert profile

The linking of the soil horizons in soil profiles is done in the feature view window that is opened by the link Soil horizons. Using the button soil features can be added. For this purpose, proceed as follows:

1. Choose Profile-Table.

2. With the button feature Feature New one new soil profile in the table can be added (See Figure View of entering the soil profile)

3. In Feature View name and description should be given (See Table Soil Profile List)

4. Using the Symbol Insert the number of the existing soil horizons can be inserted. (See Table Soil Profile list)

Soil Profile List
Parameter	Unit	Value type	Siginficance	Data type
Name	[ text ]	[ - ]	Soil Profile Key(max.8 number long characters)	Text
Soil Horizon(Link)	[ - ]	[ - ]	Each layer of a soil horizon can be assigned to a link ( maximum number of different soil layers 10).	Link
Thickness	[dm]	[ - ]	Thickness of the soil horizon.	Number
Interflow	[ - ]	[ - ]	Selection, weather interflow is allowed in this horizon.	Selection/ Choose

5.Use the drop-down menu for Soil type (link) make the links with the soil horizons.

6.Using the button Delete Features soil profile features can be deleted.
