so far functions in the flood events management at regional levels (but not at
local levels).
The Scottish side works out all the local plans in the frame of the state
organizations which keep a unified standard and the extent of GIS implemen-
tation for all the localities processed in the country. The resulting geodatabase
is thus usable for the management of flood events at all levels, regional as
well as local ones. The disadvantage of this approach for the Czech side is the
non-existence of a state organization similar to SEPA in size which would
ensure the implementation of the local project documentation at a sufficient
technological level. This work must therefore be carried out by private
subjects.
In the frame of this article, specific GIS analyses were proposed for the
change of the design of the local flood management plans, as a part of the case
study into the flood management plan of the village of Hosta
ˇ
ovice. The
specific suggestions for the use of the GIS in the local flood management
plans are the following: Determining the flow rate limits for the transversal
objects in the streams on the basis of geodesic enquiry and hydrological
computation. Similar analysis is used in the exact determination of the
flood limits (state of alert, state of emergency, state of danger) in the two
proposed water gauges which were made in the village for this purpose. Also,
another analysis which can increase the qualitative level of the local flood
management plans is the flood zones modeling and the subsequent selection
of the properties under threat. And the last suggested GIS implementation
into the local flood management plans is the analysis of the accumulated
surface wash-down for the identification of the parts of the build-up or the
village area which are under threat by the flood from the adjacent land plots.
All the above mentioned GIS implementations can qualitatively increase the
information level of the respective project documentation without any dra-
matic increase in the expenses on the project execution.
