and therefore are background ones relative to short-term
changes. The shown relative stability conditions the
existence during long time on the whole one and the same
average amount of sediments in accumulative form
composition, i.e. accumulative forms have certain lithodynamical
cubic content. It refers both to wave and
aeolian elements. Therefore the most important conclusions
are:
- aeolian processes and forms in the coastal zone differ of
those in sandy deserts and must be considered in close genetic
unity with the coastal zone development mechanism;
- the analysis of aeolian process role in the coastal accumulative
forms development must take into account
lithodynamicallongitudinal and cross structure of the coastal
zone of Seas and Oceans;
398
- aeolian processes and forms on sandy shores are necessary
element of stable development and long preservation
of barriers, bars, spits, beaches;
- according to landscape structure of accumulative form
surface, interaction of separate landscape «zones» is done
by free sediment exchange between them under the influence
of wind-sandy flow and stormy waves, which is also
a necessary conditions of stability and preservation of
these forms;
- development of narrow and wide coastal accumulative
forms, processes of sediment exchange and interaction of
separate landscape elements are different, and 250 m is a
relative borderframe of width; the wider the accumulative
form, the less longitudinal landscape elements (
