water level fluctuation - Opis:
- The results of investigations ascertain the influence of the water level regime on the erosion dynamics that was estimated according gullies volume change within the space-time between two measurements. The development of gullies in the shore zone is to a large extent influenced by the abrasion of shore slopes, which is intense at high water level in the reservoir. The minimum rate of gully development (4.5-54.7m3 yr-1) was due to the action of shore abrasion and eolian processes within the period of 2004-2007. A large positive dynamics can be attributed to the increasing number of erosion cuts. The maximum material loss from gullies (in total 627.66 m3 ) and the average volumetric retreat rate for all gullies (16.5 m3 yr-1) were recorded at the permanent lowering of the reservoir water level during the 2007-2008 period. Water level fluctuations cause cyclic changes in the dynamics of processes and initiate the new mechanism of erosion that is not typical of regular conditions.
