Model attributes (Subsidence Overlay)

The subsidence overlay also has attributes. All attributes have a default value, but can be changed to configure the subsidence calculation.

Parameter b (Subsidence Overlay) Parameter c (Subsidence Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	A			The A parameter in the Oxidation formula.	0.023537
	CLIMATE START TEMP	°C		The average temperature in the first year of the subsidence simulation.	10.1
	CLIMATE FINAL TEMP	°C		The average temperature in the final year of the subsidence simulation.	10.7
	CLIMATE_SOIL_TEMP_FACTOR			The soil temperature factor used to recalculate the climate values between 1-year calculation steps.	0.5
	DEFAULT_CLAY_THICKNESS	m		If no clay thickness value can be found in a particular grid cell, this value is used instead	0.2
	DEFAULT_PEAT_FRACTION			If no peat fraction value can be found in a particular grid cell, this value is used instead.	0.4
	DEFAULT_TOP_LAYER_THICKNESS	m		If no top layer value can be found in a particular grid cell, this value is used instead.	5.0
	HI PASSIVE DRAINAGE	m		When a drainage is active, the highest ground water level (ghg) is lowered by x meters.	-0.10
	LOW PASSIVE DRAINAGE	m		When a drainage is active, the lowest ground water level (glg) is lowered by x meters .	0.0
	YEARS	year		The amount of years to simulate during the calculation, in 1-year steps.	30
