METHOD OF PREDICTION OF DISTRUCTION OF RIVERBANKS Russian patent published in 2015 - IPC E02B3/12 A01G23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to environmental protection. For predicting the destruction of riverbanks, including the determining of adverse sites of the surveyed territories and ranking the sites, the coastal zone of the river is preliminary examined and the coastal areas with the square S equal to 1 m² are selected. Then, on each of the selected sites the site square, covered with vegetation, is determined, they are summed and the square₁ is obtained, m². Then the rate of total projective covering soil with vegetation is calculated as the ratio S₁:S,%, on the same sites the benchmarks are set at a distance of 2, 4, 6 meters from the shore horizon and the readings on the ground level on the benchmark are taken as the reference point of the condition monitoring of sites of riverbank. Then the wash height h, cm, is monthly measured at each benchmark, relative to the reference point, and then the average total index of wash height h_av in three benchmarks is calculated, then a comparative analysis of the dynamics of the processes of soil losses from coastal areas of the river bank is performed, and on its basis the relationship is set between the value of the total index h_av and the total projective cover, and then the degree of degradation of sites is evaluated, they are ranked to undisturbed and disturbed. Prediction of destruction of sites of the riverbank is made on the basis of the complex use of total index of wash height h_av and total projective cover.

EFFECT: invention provides increase in reliability of prediction of destruction of river banks.
