Environmental and resource applications
established. Similarly the proportion (%) of agricultural area or rather
agricultural values per municipality for each flood unit was determined.
With the established percentages the total values per flood unit could
then be calculated. Furthermore, with the DTM the values for different
height intervals within each flood unit could be appraised.
Within the framework of the valuation study a micro-scale analysis
was carried out for one municipality at the westcoast (Reese, 1997). The
study was based upon a detailed survey of the above mentioned values
for each parcel of land in the municipality of St. Peter-Ording. The results
were then compared with the “Wesermarsch-study” in order to optimise
the meso-scale valuation methodology.
Results
Table 1 displays the results of the valuation in summary. In all, about
218,000 people live in the study area, which comprises the are between
the State dykes and the second dyke-line at the westcoast, and the lowlands below GOD + 3.0 m at the Baltic coast. The area in danger of being
flooded during extreme storm surges along the westcoast is about four
times as large as along the Baltic coast. In spite of this the number of
people affected along the Baltic Sea coast is relatively high. The total
of protected values within the study area amounts to 37 billion German
marks (about 29 billion Euro), more than half of which is concentrated
in the Baltic Sea coastal lowlands. The reason for this is the high
concentration of people and economic values in the coastal cities along
the Baltic Sea. Large parts of the town centres of the cities of Kiel,
Lübeck, Flensburg and Eckernförde with their harbour industries are
situated below GOD +3.0 m.

With the GIS the calculated values for each flood unit can now be
selected, analysed and presented in an appropriate form. Figure 4 displays the population density for each flood unit in the district of NordFriesland. The harbour town Husum and the Isle of Sylt show the
highest population densities. On the Isle of Sylt this high density is a
result of the large number of second houses (holiday houses, etc.). The
agricultural marsh areas along the mainland coast on the other hand
have relatively low population densities.
