protection measures should be taken if needed. Along with the general guidelines for protection from
destructive natural events, the most important tasks should include
also the identification, study and
development of action plans towards the different sources of threat separately.
In order to minimize the impact of natural disasters on the settlement of population and economic
branches, the development of conception on protection from these events should be developed at state
level. In the low plain areas, every settlement, facing potential threat of flood and inundation by
different scenarios must be a subject of special control. A program on their future development and
protection should be developed.
To prevent and effectively manage floods in the Kura River, the previously existing water reservoirs
should be re-established, and mechanisms on their efficient management should be developed. A
special plan on the development of fisheries in these reservoirs should be exploited and implemented.
It is necessary to explore the amount and yearly regime of precipitations in order to reduce the
damage caused by floods in the Kur and Aras rivers and regulate the flow during a period of high water.
Taking into consideration the fact that the rivers are fed mainly with snow waters
of mountain areas, it
is necessary to increase regular observations over them.
Factors affecting the spread and intensity of destructive natural events and processes occurring in
the Kura-Aras lowland must be determined.

Research water area and compilation of materials
The research areas are the central part of the Southern Caspian, which consists of the South-western and Krasnovodsk-Cheleken
water areas in the synoptic-climatic zone of the Caspian Sea [6].
The main objective of the research is to determine the regime’s regularity and the existence of
links between the long-term
winds in these water areas of the southern Caspian Sea. In order to achieve the goal, multiple annual analog wind data, compiled
for the intersection points of the meridian 50, 51, 52 in the 39
th
parallel, were used, as well as synoptic maps and ship observation
data.
The perennial wind regime of the south-western water area
The study revealed that, for a long time (during 10 years), the recurrence of winds in the 1
st
station of the South-western water
area has been as follow: northeast 36.1%, east 9.8%, southeast 17.5%, southwest 5.6%, west 3.9% and northwest 9.4%.
Wind velocities have been observed in perennial wind speeds of up to 5-6 m/sec (38.8%). Generally, 98,8% of all winds were v
≤14m/sec and 1.0% in the range of 15-21,5 m/sec. During this period, the maximum wind speed was 21.5 m/sec, which was
observed in the north and north-east directions.
During long-term period of time (10 years), there were 39 days of strong winds and 540 quiet, windless days. This means that on
average, in the water area of research 3, 9 days pass in hurricane, 54 days are quiet, windless days.
When we compare the annual
wind regime with Sand Island, we can see that strong windy days are three time less, and quiet, windless days are 19 times more [1,
2].
Statistical analysis of perennial wind regimes on the 2
nd
station in the water area shows that here winds blew with a velocity of up
to v ≤ 14 m /sec (98, 6%). Repeated strong winds in the long-term period were equal to 14%. Such strong winds (expect eastern and
southern directions) were observed in all direction and the maximum wind speed was close to 25.9m/sec. Generally, winds in the
range of 5-6m/sec (39.2%) were observed in the research water area. It should be noted that at least (3.4%) west, and most (35.4%)
northern winds have been repeated here. Winds in the north-east (16%), south-east (12.6%) and north-west (12.5%) are
sufficiently
observed.
The study found that for a long period of time 44 days in the water area were days of strong wind, and 560 quiet, windless days.
This is an average of 4, 4 and 56 days a year.
The perennial wind regime of the Krasnovodsk-Cheleken’s water area
In result of statistical analysis, it has been discovered the recurrence of winds on the directions has been as follow: northwest
28,2%, north 21,8%, northeast 12,6%, east 11,6%, southeast 11,8%, south 3,2%, south-west 4,2% and west 5,9%.
At the time of research, the maximum wind speed in the water area was about 21, 5 m/sec.
It should be noted that for ten years, in the water area there were about 36 days of strong winds and 292 days were quiet, windless
days. This means an average of 3, 5 and 29 days per year [1].
Distribution of strong winds in the south-west and Krasnovodsk-Cheleken water area
The statistical analysis of strong winds observed over the long-term period in both water areas have revealed that the annual
repetition of strong winds is estimated to be 4,5 days in the South-western water area and 3,3 days in the Krasnovodsk-Cheleken
water area.
Scientific sources indicate that the average annual wind speed in the central part of the Southern Caspian Sea has been varied
between 4-5 m/sec [3]. In result of calculations it was obtain that the average of wind speed at the eastern coast of the water area
is 3,5-4,0 m/sec, in the south-east 2,5-3,0 m/sec, in Astara-Lankaran sea area is equal to 2,5-4,0 m/sec. In the western coast of the
water area, replications of north-western winds are of 25-45%, and in its center, the recurrence of eastern winds in summer varies
in the range of 20-50% [5].
