Рассмотрены феноменологические основы процессов фильтрации, миграции и влагопереноса, гидрогеологические особенности потоков подземных вод, принципы и критерии схематизации гидрогеологических условий, выводы и методы решения дифференциальных уравнений фильтрации и миграции подземных вод. На современном уровне изложены гидродинамические основы режима и баланса подземных вод, прогноза изменения уровня грунтовых вод в зоне влияния различных гидротехнических сооружений, теоретические основы и практические решения для водопритока к скважинам, обоснования опытно-фильтрационных работ, исследовании миграции и влагопереноса. Пособие составлено в соответствии с существующей вузовской программой для студентов гидрогеологической специальности.

Over the years, NGWA Press, the official text publishing imprint of the National Ground Water Association, has produced a number of texts with glossaries. For the first time, we have gathered all of these various glossaries into a single source, and for many of the terms we have added illustrations and photographs. The individuals named as contributing to this compilation have all contributed over the years to NGWA Press titles that have featured glossaries.

Zuverlässige Kenntnisse über die Migrationsprozesse bilden eine entscheidende Grundlage zur erfolgreichen Bewirtschaftung und zum wirksamen Schutz unterirdischer Wasserressourcen. Ihre computergestützte Simulation bildet den Kern und zugleich das Ordnungsprinzip des Buches. Sie ist die Basis sowohl für die Projektierung effektiver Maßnahmen als auch für eine optimale Prozeßführung (CAD/CAM) und setzt die Existenz simulierbarer mathematischer Prozeßmodelle voraus.

After a 20-year hiatus, we are pleased to bring you the 2nd Edition of Fundamentals of Groundwater. Like its predecessor, the book is written at an introductory level to facilitate learning and teaching, while maintaining appropriate rigor. Not surprisingly, much has changed with this edition in terms of its look and feel and importantly the content. Most obvious is the use of color in many figures throughout the book. As the book progressed, the dearth in high-quality colored figures and photographs in traditional journal articles became obvious. Fortunately, here in the United States, groundwater-related documents and reports of the U.S. Geological Survey represent a valuable treasure of high-quality graphical material.

In the preface to the first edition of Construction Dewatering—New Methods and Applications, the stated intent of the book was to be a source of practical information for engineers and contractors who must contend with groundwater on construction projects. However, current ractice includes many methods besides straightforward dewatering. The content and new title, Construction Dewatering and Groundwater Control, of this third edition reflect this.

This book provides a detailed description of how Python can be used to give insight into the flow of groundwater based on analytic solutions. Starting with simple problems to illustrate the basic principles, complexity is added step by step to show how one-dimensional and twodimensional models of one or two aquifers can be implemented. Steady and transient flow problems are discussed in confined, semi-confined, and unconfined aquifers that may include wells, rivers, and areal recharge. Special consideration is given to coastal aquifers, including the effect of tides and the simulation of interface flow.

Application of Python allows for compact and readable code, and quick visualization of the solutions. Python scripts are provided to reproduce all results. The scripts are also available online so that they can be altered to meet site-specific conditions. This book is intended both as training material for the next generation of university students and as a useful resource for practitioners. A primer is included for those who are new to Python or as a refresher for existing users.

Agricultural productivity growth is vital for economic and food security outcomes which are threatened by climate change. In the present times, changing climate is a burning issue. Climate change may be limited to a specific region or may occur across the earth.

Книга посвящена одному из актуальных направлений в подземной гидродинамике моделированию движения подземных вод и массопереносу в них загрязняющих компонентов. Подробно рассмотрены теоретические основы моделирования на основе численных методов. Особое внимание уделено вопросам физической сущности процессов фильтрации и массопереноса при использовании компьютерных технологий, оценке и проверке достоверности исходной информации и принимаемых предпосылок для разработки математической модели
