The formation of the coastal zone under the influence of groyne in the middle course of the river Belaya is researched. Protective constructions length of 15 - 45 m built at a distance of 80 - 100 m have a positive effect on coast abrasion decrease but are exposed to partial destruction. Sediment area has being increased for 10 years. The four areas are identified. The first area is with 6-8 year-old vegetation, the second one is with a 2-3 -year-old, the third area is with 1-year-old vegetation, the fourth one has no vegetation at all . Sediment thickness has been decreased from the bank of the river to the water’s edge from 2.1 to 0.1 m. Vegetation biodiversity has been decreased from the groyne bottom (at the banks of the river) to their end. Poplar, willow and alder are dominated. It is assumed that for groyne efficiency is reasonable to reduce the space between groynes to a half.
