In accordance with the federal target program for the development of resorts in the North Caucasus, the Government of the Russian Federation announced its intention to build five more modern ...European-class ski resorts in the region over the next 10 years. Construction of complexes, including in the village of Veduchi (Chechen Republic is planned). In the territory of the "Veduchi" resort such dangerous exogenous processes as avalanches are largely developed. This work is devoted to engineering and hydrometeorological surveys for the object "Skiing infrastructure on the north-oriented slope of the Veduchi ASTRC", assessment of avalanche danger.
The paper is devoted to the comparison of different approaches to parallel solution of 3D forward and inverse problems of airborne electromagnetic (EM) surveys when multidimensional processing of ...data obtained on large areas is needed. The mathematical models for the solution of 3D forward and inverse problems and different methods of their parallelization are considered. The results of numerical experiments for the airborne EM survey problem, which is typical of prospecting the kimberlite bodies in Eastern Siberia, are presented. It is shown that the combination of different techniques of parallelization in a distributed computational system, taking into account the specifics of the numerical schemes implementation for forward and inverse problems solution, makes it possible to achieve the speedup close to linear.
The paper presents a new approach to construction of complex geological models and generation of finite element meshes in order to perform 3D modeling and multidimensional processing of airborne ...geophysical data. The main principles of geological models construction are considered. They are based on defining geological models in terms of the subject field and take into account their main specifics: complex background media, curvilinear Earth surface relief and borders between the geological layers, complex shape of target objects, etc. We consider the necessary data structures and specifics of finite element mesh generation. The example of generation of the finite element mesh for a geological model typical of airborne geophysical surveys is shown.
Automated monitoring systems of debris flow hearths, their purpose, and the role in decreasing debris flow risks are considered. A brief review of the tools for measuring parameters of debris flows ...used in systems for monitoring and warning of debris flow hazards is given. The description of foreign and Russian hardware–software systems for monitoring debris flow hearths is presented.
