The following data must be available for all elements and nodes for the top element or node layer in the model file:

 

Ground level (attribute GELA ). To calculate the relief energy or the slope to take into account the surface runoff based on Schroeder and Wyrwich.

 

Initial potential heads: To calculate the distance to water level. The conversion of node in element values is done automatically within the recharge calculation.

 

Soil type (attribute NSBT): The soil type must be specified in the model file according to the following classification as an element attribute:

Soil type	Classification (= NSBT)
Terrestrial sand soils	0
Terrestrial clay soils	10
Semi terrestrial soils	20, 21, 22

 

Degree of sealing (attribute VERS): The degree of sealing is specified for each element in the unit [%]. It is necessary to calculate the conditional sealing surface runoff.

 

Land use class (attribute NSFN): The land use class must be specified according to the following classification for all elements in the model file:

 

Land use	Classification (= NSFN)
Farm-, grassland	0
Decidous forest	1
Mixed forest	2
Coniferous forest	3
Build-up areas	4
Water areas	5
