Class BWDModel

java.lang.Object

lerfob.windstormdamagemodels.bockwindddamagemodel.BWDModel

public final class BWDModel
extends java.lang.Object

This class implements the wind damage model found in Bock et al. 2005. This model is designed for beech stands in NorthEast France.

Method Detail

getProportionOfDamagedTrees

public double getProportionOfDamagedTrees(BWDStand stand,
                                          double windSpeed)
                                   throws java.lang.Exception

This method returns the proportion of damaged trees always in terms of number of stems. The calibration data come from a sample in Northeastern France. The mean wind speed is around 120-140 km/h, with some above 140 km/h (very few observations below 120 km/h).

Parameters:

stand - = a BWDStand instance

windSpeed - = the windspeed in km/h (double)

Returns:

the proportion of damaged trees (double)

Throws:

java.lang.Exception

getProbabilityOfDamageForThisTree

public double getProbabilityOfDamageForThisTree(BWDTree tree)
                                         throws java.lang.Exception

This method returns the probability of wind damage for an individual tree. It is designed for wind speeds above 140 km/h. The calibration data mostly come from the For�t de Haye (see Vincent Badeau's thesis).

Parameters:

tree - = a BWDTree instance

Returns:

the probability of stand damage (double)

Throws:

java.lang.Exception
