<abstract>
<p>Flood risk communication with the general public and the
population at risk is getting increasingly important for flood risk
management, especially as a precautionary measure. This is also underlined
by the EU Flood Directive. The flood related authorities therefore have to
develop adjusted information tools which meet the demands of different user
groups. This article presents the formative evaluation of flood hazard maps
and web mapping services according to the specific requirements and needs of
the general public using the dynamic-transactional approach as a theoretical
framework. The evaluation was done by a mixture of different methods; an
analysis of existing tools, a creative workshop with experts and laymen and
an online survey.
&lt;br&gt;&lt;/br&gt;
The currently existing flood hazard maps or web mapping services or web GIS
still lack a good balance between simplicity and complexity with adequate
readability and usability for the public. Well designed and associative maps
(e.g. using blue colours for water depths) which can be compared with past
local flood events and which can create empathy in viewers, can help to
raise awareness, to heighten the activity and knowledge level or can lead to
further information seeking. Concerning web mapping services, a linkage
between general flood information like flood extents of different scenarios
and corresponding water depths and real time information like gauge levels
is an important demand by users. Gauge levels of these scenarios are easier
to understand than the scientifically correct return periods or annualities.
The recently developed Bavarian web mapping service tries to integrate these
requirements.</p>
