The case study of a flood management plan in the village of Hosta
ˇ
ovice, on the
southern fringe of Moravian-Silesian region, was performed in order to put forward
a proposal of specific GIS implementations in the local flood management plans.
Characterization of the Locality in Question
The village of Hostaˇovice is located near the western edge of the Natural Forest
Region 39—Silesian-Moravian Foothills. The Natural Forest Region (hereinafter
NFR) of Silesian-Moravian Foothills is an autonomic forest area bounded by the
state border with Poland in the northeast, neighboring with the Beskids NFR (40) in
the south and with the NFR of Low Jesenik (29) in the west. The area lies
approximately between 17
55
0
and 18
47
0
of east longitude and between 49
32
0
and 49
57
0
of north latitude (Holuˇa et al.
2000
).
The highest situated point in the village cadastre is the peak of Pohorelec
(551 m a.s.l.), median absolute altitude of the village cadastre is 380 m a.s.l., the
lowest situated point is 347 m a.s.l.
Following the Quitt classification, a major part of the village is located in a
moderately warm area (MW 2 and MW 9), and the southern part is located in a cold
area (C 7). The average annual air temperature ranges between 7 and 7.5
C, with
January as the coolest month and July as the warmest month. The average annual
rainfall is above 850 mm, with the biggest amount of rainfall in July, and the lowest
one in February. As far as winds are concerned, the N-S directions prevail (Demek
et al.
2006
).
The main European sea-drainage divide runs through the local cadastre of
Hosta
ˇ
ovice, with 43.6 % of the cadastre land belonging to the Black Sea drainage
area, and 56.4 % belonging to the Baltic Sea drainage area. Hydrologically, the area
is divided between the Morava basin and the Odra basin. The whole cadastre area is
drained off by four streams, namely by the stream called Stran´k and by Zrz´vka,
belonging to the Odra basin, and by the streams called Jasenice and Krhova being a
part of the Morava basin. With respect to the flood risks in the area, two inflows
from the right into the stream Stran´k are relevant: streams called Hr´zkov´ potok
and B´l´ potok which flow through the village build-up area and they go through
pipes at several points. The hydrological ID numbers of these two streams are ID
10208697 and 10217822 respectively.
