This research is aimed at developing the remote sensing technique for assessing probability of impact on linear engineering structures by the example of lateral river erosion. The suggested approach for assessing probability of impact on linear engineering structures takes into account the process of lateral erosion, bending and straightening of bends is at the same time the main formatting factor for the landscape morphological pattern of alluvial plains. The base of the technique is a mathematical model of the landscape morphological pattern for alluvial plains. It was essentially tested at key sites within river valleys in different nature environments. The exponential distribution of arrows of the packages and time of bend development is a general law of the landscape morphological pattern of the alluvial plains in different nature environments; numerous testing results confirm it. The model of the alluvial plain morphological pattern gives a solution of the quantitative assessment of the impact probability to a linear structure by river erosion under limited conditions; the necessary parameters can be estimated from the remote sensing data.

Key words: mathematical morphology of landscapes, alluvial plains, probability of impact to engineering structures, remote sensing data techniques, modelling, river erosion
