Abstract In designing artwork as bridges, hydraulic calculations have a very important role due to the fact that they are behind their sizing. Bridge designer must therefore possess knowledge of hydrology, hydraulics of bridges and river banks regularization. A problem that arises during the design stage of bridges is the scour phenomenon surrounding bridge pier. Over time, there have been conducted a number of studies which led to the provision of a plurality of mathematical models that are intended scour prediction. In the present article we will present an experimental study to determine the bed profile and measurement of scours products around a pier bridge using 3D terrestrial laser scanner.

It has been studied that major drawbacks in formulating the requirements for the reliability of water supply and sewerage systems in existing regulations are related to the fact of their being formulated in the first part of the XXth century. These regulations dont take into account the latest achievements in the reliability theory appeared and developed successfully in the second part of the XXth century. Among these achievements there is a methodologically correct selection of indices for estimating the reliability of complex technical systems. The selection of science-based reliability indices for water supply and sewerage systems and their introduction in the existing regulations is the task of primary importance.

Structure Of Knowledge

The article analyzes a number of methods of knowledge formation using various graph models, including oriented, undirected graphs with the same type of edges and graphs with multiple and different types of edges. This article shows the possibilities of using graphs to represent a three-level structure of knowledge in the field of complex technical systems modeling. In such a model, at the first level, data is formed in the form of unrelated graph vertices, at the second level – information presented by a related undirected graph, and at the third level – knowledge in the form of a set of graph paths. The proposed interpretation of the structure of knowledge allows to create new opportunities for analytical study of knowledge and information, their properties and relationships.
