Evaluation

The river Stoer is part of the Elbe catchment, therefore in the following potential damage analysis damage functions of the IKSE are used.

Damage functions for agriculture should reflect also the new approach for calculating the asset values. The damage functions are determined for asset values based on net asset value at actual price.

Arable 

The damage potential for arable areas is calculated by a factor which is independent from water stage and duration time. Inundation of arable land causes a 100 percentage loss of crop.

Meadows 

A flood event will destroy only one harvest. Therefore an averaged damage asset of 225 /ha will occur (adoption: 15 m/ha and 15 /m) with a damage factor of 100 percent.

Forest 

During an inundation of forest no damage will occur, if water depth declines after some days. An averaged damage factor of 5 percent causes an asset value of 40,5 /ha.
