erosion

A model of hydro-erosion wear of sealing elements was constructed taking into account a set of parameters that reflect the physical properties of the fluid and the material of the sealing elements, as well as the design parameters of the valves. To determine the dependence of the rate of erosion wear on a complex of parameters, we use the π-theorem of similarity and the method of dimension analysis. An expression is given that determines the change in the thickness of the erosive fracture of the sealing surfaces in time.

Research conducted within Kalush-Golinskii potassium salt deposit. The analysis of symmetry systematic approach errors in the geological interpretation is directed. As a result of interpretation revealed that erosion solt mirrors has  flat character and should be taken into account in predicting the day surface subsidence. The authors proposed new original approaches to complex interpretation of these methods for mapping geological section.

Object of study. Planned distribution establishment of erosive “spots” of the agricultural lands is based on the processing of binary images of aerial photographic materials using morphological and planimetric methods of analysis. Methodology. Offered methodology is based on the non-linear operators’ application.

A basic principle of good practice is to consider a range of alternatives in technical measures of bank protection proposal. There are several solutions of river bank protection and stabilisation. In the draft proposal all these alternatives have to be considered with respect the best practical environmental option. In this paper the overview of relevant engineering options regards to the most suitable and sustainable type of bank protection and stabilisation will  be described.
