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.

Монография представляет собой фундаментальное обобщение больших региональных материалов по геохимии литогидросфе-ры на основании всестороннего изучения иловых, поровых вод и всей окружающей их среды. Во внутренних морях и океане выявлены региональные, фациальные и генетические закономерности формирования химического состава иловых вод на стадиях седиментации, диагенеза и эпигенеза донных отложений.

Методика базируется на представлении о трещиноватых скальных массивах, служащих основаниями крупных инженерных сооружений, как о дискретной, неоднородной и анизотропной среде зонально-блочного строения. Работа включает обоснование и методику анализа данных опытно-фильтрационных полевых работ и их интерпретацию при распространении на пространство скального массива в форме масштабно-понятийных моделей водопроницаемости. Составлена в лаборатории инженерной геологии и геокриологии ВНИИГ им. Б. Е. Веденеева. Предназначена для инженеров-геологов, гидрогеологов, проектировщиков, занимающихся обоснованием гидротехнического строительства.

Characterizing and understanding the variability of hydroclimatological processes and measurements are essential for assessing the performance of water resources infrastructure and its management and for planning successful and efficient water resources projects.

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.

Hydrologic Analysis and Design is intended for a first course in hydrology. It introduces the student to the physical processes of the hydrologic cycle, the computational fundamentals of hydrologic analysis, and the elements of design hydrology.

Inadequate in situ observations have been historical barriers in the development of hydrologic science. Additionally, with the changing climate and ever accelerating human activities, it is anticipated that water-related disasters such as flood, landslide, and drought will be more severe and frequent, thus threatening more regions around the world. Flooding, which is considered as one of the most hazardous disasters in both rural and urban areas, accounts for around one-third of all global geophysical hazards and causes significant human suffering, loss of life, and property damage.

Вода - основа жизни. Весь отведенный ему для жизни срок человек пользуется ежедневно этим бесценным даром природы. Автор этих воспоминаний, всю свою жизнь посвятивший служению воде в увлекательной форме, рассказывает о людях, с которыми ему приходилось вместе решать подчас непростые водные проблемы в разных регионах страны и зарубежом

Water is among the most essential resources that sustain Earth’s ecosystems, but these systems are currently under threat due to land use and climate change. Assessing the impact of this global change on water security and ecosystem’s functions is not only the key concern of the United Nation’s Sustainable Development Goals, playing a key role in sustainable development of society, but also the most important research focus in “Future Earth” and Earth critical zone research.
