Traditionally, hydrogeology is defined as the area of geologic sciences, as well as engineering, that in its broadest sense deals with water below the land surface. Hydro is the Greek word for water, and geology is the science of Earth: geo being a prefix derived from the Greek word gaia (meaning the earth, but also Gaia – a primordial Earth goddess in Greek myth), whereas logy is derived from the Greek word logos which means word, thought, principle, or speech, but in modern times is most commonly understood to mean science. Thus, geology literally means the science of Earth.

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.

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.

The field of hydrological science deals with the occurrence, distribution, movement, and properties of water on the earth. The science of hydrology holds a unique and central place in the field of earth system science, intimately linked with other water-related disciplines such as meteorology, climatology, geomorphology, hydrogeology, and ecology. Beyond basic scientific interest, water quantity and water quality have become two of the most pressing environmental issues of our time.

This report is a product of the Committee on USGS Water Resources Research, which provides consensus advice to the Water Resources Division (WRD) of the U.S. Geological Survey (USGS) on scientific, research, and programmatic issues. The committee is one of the groups that works under the auspices of the Water Science and Technology Board (WSTB) of the National Research Council.

В монографии систематизированы и обобщены данные о миграции фосфора на разных этапах глобального гидрологического цикла. Приведены новые оценки среднего содержания фосфора в атмосферном аэрозоле, атмосферных осадках, водах первичной гидрографической сети, средних и крупных рек мира. Определены потоки фосфора в атмосфере, материковом стоке, Мировом океане.

С целью выработки у будущих инженеров-строителей навыков оценки качества геологической среды при возведении сооружений, необходимыми являются знания об инженерно-геологических изысканиях. Информация о инженерно-геологических изысканиях содержится в водной части.
В первой лабораторной работе изучается построение инженерно-геологического разреза, что является важнейшей частью проектирования в строительстве. Вторая работа посвящена построению карты гидроизогипс и выполнению расчетов по ней.
