hydro-geological features of the Fruska gora
are directly conditioned by the complexity of its geological structure,
the spatial distribution of the individual types of rock masses, and
their interrelations, porosity of the rock masses and the rainfall that
feeds the subterranean waters.
According to the size of the pores, there
are all of the three basic structural types of porosity: intergranular
(in sands and related rocks), fissured (hard cracked rocks) and
cavernous (limestones). In them, there are springs of the respective
structural type, namely: compacted (free, artesian and sub artesian),
broken up and combined.
Springs of a broken structural type have
been formed in all kinds of hard rock masses of the Fruska gora. The
volume of accumulated water is small. It mostly depends on the degree
and pattern of the cracked ness of the rock mass. These waters are
important from the viewpoint of the appearance of a large number of
springs, especially in the source parts of almost all springs and
smaller brooks flowing into them (particularly in flysch-like sediments
of the upper Cretaceous, shale of various types, etc.). Somewhat larger
volumes of water can be expected in limestones, particularly of the
Triass age. In limestones, it is possible to find a specific form of
them, i.e. cavernous (karst) sources.
In terms of the importance of the sources
of the broken structural type related to the volumes of water and water
supply of larger settlements, it should be emphasized that the volumes
in this type are very limited.
The largest exploitable volumes of ground
water appear in the alluvial sediments of the Danube. In the littoral
zone of Novi Sad, water is pumped from these deposits for the supply of
the city and the surrounding settlements. However, it should be pointed
out that the reserves of water of this type are also limited, new
sources must be sought and the reserves economically and prudently
managed and exploited.
Tertiary sands, on the edges of the
mountain, appear in many places on the surface. They accumulate
significant volumes of ground water that feed the water-bearing horizons
of the tertiary series. Research and exploitation pumps have detected
and confirmed ground water at several locations (Cerevic, Banostor, Novi
Sad and a broader area of southern Backa). Three water-bearing horizons
have been identified.
The first one is 50m deep,
hydraulically connected with the alluvial water-bearing environment;
optimum debit of vertical wells is 5-10 lit/sec.
The second one is up to 130m deep, with
good filtration characteristics and debit of 20 lit/sec.
The third horizon is 170 to 210m deep,
with an optimum debit of 5-17 lit/sec.
CLIMATE AND WEATHER
By its location, the area of Fruska gora
mountain should have continental climate, but cover of forests changes
this type of climate into a climate with sub continental
characteristics. Exception is the climate of the mountain's ridges, with
cold winters and chilly summers.
Sunny mornings, possible afternoon
thunderstorms and cool nights. Weather conditions may change quickly in
mountainous area. Wear appropriate dress for each season - comfortable
clothing, dress in layers, rain gear, sunglasses and sunscreen.
Unpredictability is the key word for
mountain weather in the Fruska gora Mountain. As a result, Park visitors
cannot be indifferent about the weather and should be prepared for
sudden weather conditions. Cold fronts may down temperatures to -30
degrees C. All visitors should be equipped to handle these conditions,
and particularly overnight frosts.
