UNDER THE CONDITIONS OF HEAVY STORMS IN 2007

On the basis of the wind-energy method, we estimate the distributions of the parameters of a longshore
flux of sediments formed near the west coast of the Bakal’skaya Spit (in the northwest part of the Cri-
mea) under the conditions of heavy storms whose action caused a significant erosion of the west coast of
the spit and retreat of the coastline in January and November 2007. The calculations are carried out by
using the actual directions and velocities of the winds recorded in the investigated region. We analyze
the trends of changes in the formation of the coastal zone caused by the nonuniform distribution of the
intensity of longshore transportation of sediments. In analyzing the causes of formation of gullies in the
barrier of the Bakal’skoe Lake and in the narrow distal part of the body of the spit, we make an attempt
of interpretation of the quantities characterizing the force of the frontal action of waves. The obtained
numerical results are confirmed by the data of field observations.
The Bakal’skaya Spit is located in the Karkinitsky Gulf of the Black Sea (Fig. 1). From the morphological
point of view, this spit is a free dual accumulative form of the coastal features about 8 km in length . The
Bakal’skoe Lake is located in the near-basal part of the body of the spit. Its west side is separated from the
neighboring water area of the sea by a barrier of about 50 m in width (on the average). The territory of the spit
is a part of the Bakal’skaya Spit regional landscape park with an area of 1520 ha . This landscape park is a
popular local seaside resort, and the recreational potential of its sand beaches 30–70 m in width is used fairly
As a result of the passage of a heavy storm over the water area of the Black Sea on January 24–25, 2007 and
a catastrophic storm on November 11–12, 2007, the west coast of the Bakal’skaya Spit suffered significant ero-
sions and strong changes in the coastline. Thus, the first storm led to the retreat of the coastline by up to 50 m.
As a result, a part of the road, a power transmission line, and capital buildings were destroyed. Moreover, a
gully was formed in the north part of the barrier of the Bakal’skoe Lake. The action of the second storm led to a
subsequent retreat of the west coast, which was also accompanied by the destruction of objects of the infrastruc-
ture. In this case, the gullies were formed not only in the barrier of the lake but also in the body of the spit (in its
narrow section). Thus, the expedition of the Marine Hydrophysical Institute of the Ukrainian Academy of Sci-
ences held on November 20, 2007 observed a gully of about 300
m in width, which completely separated the
most distant (distal) part of the spit from its main body .
