The Second European Conference on Geostatistics for Environmental Applications took place in Valencia, November 18-20, 1998. Two years have past from the first meeting in Lisbon and the geostatistical community has kept active in the environmental field. In these days of congress inflation, we feel that continuity can only be achieved by ensuring quality in the papers. For this reason, all papers in the book have been reviewed by, at least, two referees, and care has been taken to ensure that the reviewer comments have been incorporated in the final version of the manuscript. We are thankful to the members of the scientific committee for their timely review of the scripts. All in all, there are three keynote papers from experts in soil science, climatology and ecology and 43 contributed papers providing a good indication of the status of geostatistics as applied in the environmental field all over the world. We feel now confident that the geoENV conference series, seeded around a coffee table almost six years ago, will march firmly into the next century. <...>

Рассмотрены спектральные, корреляционные и кепстральные методы выделения сигналов из помех, использованные в оригинальных натурных и численных опытах. Среди них: выделение и измерение параметров сигнала при локации объекта на просвет; сжатие во времени узкополосного сигнала путем преобразования его спектра; устранение искажений сигнала, вызванных многолучевостью, с использованием лишь искаженного сигнала (слепая дереверберация); метод определения задержки импульса, флуктуирующего по форме; исследование распространения волн с помощью М-последовательностей и другие. Приведены численные расчеты с программами - 37 программ в пакете Mathcad б 0 plus.
Книга написана на основе лекционного курса и предназначена для студентов, аспирантов и специалистов, интересующихся численными методами выделения сигналов на фоне помех.

В пособии изложены некоторые теоретические и практические вопросы решения прямых задач гравиразведки и магниторазведки.
Для студентов геофизических специальностей.

This book is a practical, hands-on introduction to numerical geodynamic modelling for inexperienced people, i.e. for young students and newcomers from other fields. It does not require much background in mathematics or physics and is therefore written with a maximum amount of simple technical details. If you are inexperienced – this book is for you! <...>

Рассмотрены аналитические и численные модели геомиграции, составляющее основу для количественных оценок текущего состояния качества подземных вод и про-гнозирования изменения этого состояния под влиянием техногенных факторов, а также для экспериментального изучения гидрогеологических параметров. Исследование, направленное на развитие фундаментальных знаний о миграции подземных вод, иллюстрируется примерами решения разнообразных практических задач применительно к конкретным объектам гидрогеологических изысканий (исследований). Среди этих задач: прогнозирование переноса (посредством конвективной дисперсии, плотностной конвекции при однофазной фильтрации подземных вод и гравитационно-капиллярных сил в многофазных потоках) техногенных загрязняющих компонентов и жидкостей в во-доносных горизонтах и зоне аэрации, анализ формирования природных гидрогеохими-ческих границ и закономерностей их смещения под влиянием водоотбора, датирование подземных вод по изотопным данным, палеореконструкция условий формирования подземных вод, интерпретация данных полевых индикаторных опробований и опытно-миграционных наблюдений, расчленение гидрографов речного стока с привлечением изотопных данных, описание формирования эвапоритовых залежей солей в замкнутых бассейнах и др.
Для гидрогеологов — научных работников, специалистов и студентов.

Although geologists have dabbled in numbers since the time of Hutton and Playfair, 200 years ago (Merriam 1981e), geology until recently lagged behind other sciences in both the teaching and geological application of mathematics, statistics and computers. Geology Departments incorporating these disciplines in their undergraduate courses are still few (particularly outside the USA). Only two international geomathematical/computing journals are published (Computers & Geosciences; Mathematical Geology), compared with dozens covering, say, petrology or mineralogy. It also remains common practice for years (and $1000s) to be spent setting up computerized machines to produce large volumes of data in machine-readable form, and then for geologists to plot these by hand on a sheet of graph paper! <...>

Proceedings of the seventh European conference on geostatistics for environmental applications / Материалы Седьмой Европейской конференции по геостатистике для применения в окружающей среде

Characterising spatial and temporal variation in environmental properties, generatingmaps from sparse samples, and quantifying uncertainties in the maps, are key concerns across the environmental sciences. The body of tools known as geostatistics offers a powerful means of addressing these and related questions. This volume presents recent research in methodological developments in geostatistics and in a variety of specific environmental application areas including soil science, climatology, pollution, health, wildlife mapping, fisheries and remote sensing, amongst others.

Land forms and drainage patterns are being studied by more and more elaborate methods all the time. The increasingly accurate methods of measuring land form and geomorphological processes are providing a vast amount of quantitative data. This has to be analysed by numerical methods so that an orderly behaviour may be discerned from amongst the mass of accumulated data. This book sets out to provide an introduction to those numerical methods which we have found to be most useful in the analysis of geomorphological data.

Modern geochemistry utilizes three powerful tools: (major and trace) elements, isotopes, and equations, to study various Earth and environmental processes. A combination of the experimental tools (elements and isotopes) with theoretical tools (equations) provides penetrating insights into the Earth and environmental processes. The aim of this book is to link equations more closely with geochemical measurements, including elemental abundances and (radiogenic, radioactive and stable) isotopic compositions. The importance to use equations in scientific research has been best stated by Albert Einstein, "Equations are more important to me, because politics is for the present, but an equation is something for eternity." <...>
