Class KA6Functions

java.lang.Object

net.simplace.sim.components.soil.pedotransfer.KA6Functions

All Implemented Interfaces:

TextureClassPedoTransferFunction

public class KA6Functions
extends Object
implements TextureClassPedoTransferFunction

Developed to determine soil hydraulic properties (do not use)

NOT CORRECTLY IMPLEMENTED!

Kartierungsanleitung Function are developed to determine soil hydraulic properties e.g., field capacity at 18,25 and 35 bar, wilting point, saturated hydraulic conductivity, saturation for different soil texture classes based on German soil texture classification. The input data used for this estimation are the percentage of silt and clay, percentage of organic matter and bulk density.

Units

Parameters	Units
Bulk Density	g/cm3
Saturation	Vol%
Available Water	Vol%
Field Capacity	Vol%
Wilting Point	Vol%
Saturated Hydraulic Conductivity	cm/day

K > 0, a > 0, n > 1 and -10 < l < 10
