Theme of the paper is the solution of flooding geomodels creation for Dniester river basin territory, which uses contact and remote measurements. Natural and anthropogenic factors causing groundwater level rising were analyzed for localization of flooded zones and forecasting of geometric characteristics. Geographic information systems for researched area include the spatial binding of the hydrological elements and observation points, digital model of relief preparation, basin allocation catchment, flooded areas modeling. Structural features include the size and shape of object, brightness disposal within the object, image texture, some others. Possibility of available remote sensing data use allows reducing temporal and economic cost for conducting additional ground measurements for possible flooded areas determining. These methods of geomodels creation are realized for the territory of Dniester Canyon, the hydrogeologic feature of which is connected to the Upper Cretaceous horizon and groundwater.

The analytical dynamic compliance of an elastic pipe pile fully buried in a fluidfilled and porous-viscoelastic soil stratum resting on rigid bedrock and subjected to a vertical time-harmonic load is proposed. In this study, the Hamilton's principle of dynamics is employed to establish the governing equations for the pipe pile, which is treated as a two-dimensional (2D) hollow bar structure. The outer and inner soil media surrounding the pipe pile are considered as three-dimensional (3D), homogenous, and liquid-saturated porous continuum, besides they are described by the porous-elastic media model proposed by de Boer. The governing equations for the pipe pile and the soils are solved with the aid of the separation technique of variables, and also utilizing the boundary and contact conditions of the pipe pile and the soils. Then, the analytical solution for the vertical dynamic compliance of the pipe pile is derived. By comparing with the existing solutions and finite element model (FEM), the results from the newly proposed method confirm its validation. Comparative analyses of numerical examples are finally conducted to reveal the variations and response principle of the dynamic compliance of the pipe pile under different material/geometry parameters.

“…It should also be noted that to increase the efficiency of numerical calculation in recent decades has become widely used method of physical simplification. This method is widely used in solving modeling problems of engineering problems and is to simplify the equations of mathematical physics by introducing simplifications that take into account the physical content of processes [41][42][43][44][45][46][47][48][49][50][51].…”

Determining the quantitative degree of connection between logging error and the corresponding error of oil and gas wells electrometry inverse problem solving is considered. A quantitative method to determine the magnitude of the error of solving the inverse problem depending on the magnitude of the logging error for a given model of a single layer or section as a whole is described. Examples of determining the error of the inverse problem for real well materials, taking into account the actual measurement error, are given. A method for determining the characteristics of the spatial resolution of electrometry methods is described. Examples of its use for low-frequency induction logging equipment are given. The proposed methods allow to determine the areas of equivalent solutions and the areas of existence of stable / unstable solutions of the inverse electrometry problem.
