PROTECTION OF IN-DEPTH PARTS OF STRUCTURES
IN THE FLOODED AREAS OF SOUTHERN UKRAINE
Introduction. At the 5th World Water Forum (Istanbul, 2009), the group
established a list of the main types of harmful effects of water and its consequences in
the act entitled "Prevention and Action to Minimize Death and Destruction: Building
Resilience Toward Sustainable Development" [1]. They are:
1 - consequences of flooding, leading to flooding of lands and human settlements;
2 - destruction of shores, protective dams and other structures;
3 - waterlogging, flooding and salinization of lands caused by an increase in the
level of groundwater due to irregular water supply during irrigation, water leakage
from water supply and sewerage systems and overlapping groundwater flows when
large industrial and other structures are located;
4 - land drainage caused by the groundwater abstraction in a volume exceeding
the established volumes for their selection;
5 - pollution (salinization) of land in areas of mining, as well as after the end of
field operation and conservation;
6 - erosion of soils, formation of ravines, landslides and mudflows.
Due to global climate changes, the frequency and amplitude of natural
fluctuations in river flow increases, it increases the risks of manifestations of the
harmful effects of water, the damage from which for Ukraine is estimated
approximately of 1,5-2,0 billion hryvnas per year [2].
The most active dangerous exogenous geological processes (EGP) include
landslides, karst, underflooding, abrasion, processing of the banks of reservoirs, and
subsidence of the earth's surface. All these processes are typical for the South of
Ukraine (Kherson, Nikolaev, Odessa region and Autonomous Republic of Crimea).
Kherson region was chosen as a key research area, which is typical for the South of
Ukraine.
For this territory, the carrying out of water management activities, which has such
negative consequences as: filtration losses from irrigation systems, reservoirs, canals,
