В последнее время термин денудация, введенный еще П. Скро-пом '), получил различные толкования. Одни2), придерживаясь буквального значения слова (denudo = обнажаю), разумеют под именем денуда-' ции только те процессы обнажения, которые происходят вследствие удаления рыхлых продуктов выветривания. Другие 3), напротив, выветривание совершенно выделяют из процессов денудации и причисляют к ним только те обнажения, которые происходят от действия ветра, текучей воды, льда и моря; при этом собственно денудацию (Denudation) противопоставляют отложению (Auflagerung). Третьи4) придают ему более широкое значение, но с различными ограничениями.

Пятилетняя работа в области почвенно-дорожных исследований, составляя одну из крупных заслуг почвоведения, была полна трудностями. Между идеей и ея осуществлением лежит огромный творческий путь, во время которого формируется прикладное и практическое применение научной дисциплины.

Plate tectonics is the unifying theory of the solid Earth that describes the surface of our planet as being fragmented into rigid plates that move in relation to each other. Many fundamental geological processes, such as earthquakes, volcanism, and the formation of mountains, occur at the plates’ boundaries. In its initial formulation, plate tectonics was a kinematic theory that described and quantified these movements and associated deformation. Plate tectonics evolved into a dynamic theory, describing the forces driving the surface deformation and the internal dynamics of our planet. We also came to realize that plate tectonics is only one of the possible tectono-magmatic styles in which a planet can operate and that these can change over time. In the past years, the geosciences community has started to develop a theory that integrates plate tectonics and mantle convection as part of a single system. This was possible because of the ever-increasing high-quality imaging of Earth’s interior and our computational capabilities. But while the progress has been enormous, there are still many uncertainties and challenges ahead. <...>

Development and use of polymeric materials in the form of geosynthetics and fibres as a new class of construction materials have revolutionized the infrastructure and the environmental protection works in the construction industry during the past three to four decades. Geosynthetics are available in a wide range of compositions appropriate to different applications and environments.

Natural hazards are potentially damaging physical events and phenomena, which may cause the loss of life, injury or human life disruption, property damage, social, economic, and political disruption, or environmental degradation. Natural disasters cause fear and horror for people. The most unpredictable is earthquakes.  Active volcanoes are constantly monitored that gives the possibility to anticipate a possible eruption. Tsunamis have a number of predictive features that give possibility to mitigate their consequences.

Geology today demands the knowledge of a large number of fundamental ideas which are provided by neighboring sciences. The student, or the geologist at the beginning of his career, runs the risk of losing himself in a multitude of details and complications, which will seldom be useful to him. To guide him, we have endeavored to prepare a work which is easy to read, not overburdened with tables and graphs, and which avoids swamping the reader with all the details of many specialized disciplines. Our aim is to stress the general facts and to bring out the conclusions which will enable the reader to reconstruct the great events that have taken place in the past on the surface of the earth. <...>

This edited volume compiles the state of the art in research on the geological record of tsunamis and other extreme-wave events and guides the reader in designing goaland site-specific research. It has evolved from an initial idea, first explored by the editors in early 2016, to final publication online and in print in mid-2020. The motivation for developing a handbook-type compendium on this topic was driven by the observation that such a unifying volume devoted to this particular discipline, which lies at the crossroads between sedimentology and tsunami science, was missed by the scientific community.
