About
The IAH is a professional association for those within disciplines and employment related to groundwater, its occurrence, utilization, testing and management. IAH was established to foster closer ties, cooperation and information exchange related to the study of groundwater. IAH is non-government and non-profit and has over 3800 members internationally from around 135 countries. The Association is affiliated with the International Union of Geological Sciences (IUGS), and was founded during the 20th International Geological Congress in 1956.
A professional association seeks to further a particular profession, the interests of individuals engaged in that profession and the public interest. In the United States, such an association is typically a nonprofit organization for tax purposes.
Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
Non-governmental organizations - commonly referred to as NGOs, are usually non-profit independent of governments, many are active in humanitarian etc. areas; however, NGOs can also be as lobby groups for corporations, such as the World Economic Forum. NGOs is also sometimes expanded to nongovernmental or nongovernment organizations. They are thus a subgroup of all organizations founded by citizens, which include clubs and other associations that provide services, benefits, and premises only to members. Sometimes the term is used as a synonym of "civil society organization" to refer to any association founded by citizens, but this is not how the term is normally used in the media or everyday language, as recorded by major dictionaries. The explanation of the term by NGO.org is ambivalent. It first says an NGO is any non-profit, voluntary citizens' group which is organized on a local, national or international level, but then goes on to restrict the meaning in the sense used by most English speakers and the media: Task-oriented and driven by people with a common interest, NGOs perform a variety of service and humanitarian functions, bring citizen concerns to Governments, advocate and monitor policies and encourage political participation through provision of information.
The IAH publishes the Hydrogeology Journal eight times a year and two book series. In addition it provides various resources for those in the groundwater community.
Hydrogeology Journal is a peer-reviewed scientific journal published eight times a year by Springer Science+Business Media. It was established in 1992 and is the official journal of the International Association of Hydrogeologists. The journal publishes papers on both theoretical and applied aspects of hydrogeology. Papers focus on integrating subsurface hydrology and geology with other supporting disciplines to explain phenomena observed in the field. The journal has a 2013 impact factor of 1.718. The editor-in-chief is Clifford I. Voss.
Hydrology is the scientific study of the movement, distribution and management of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is called a "hydrologic engineer", working within the fields of civil and environmental engineering. Hydrologists can also be scientists studying earth or environmental science and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.
The United Nations General Assembly declared 2008 as the International Year of Planet Earth to increase awareness of the importance of Earth sciences for the advancement of sustainable development. UNESCO was designated as the lead agency. The Year's activities spanned the three years 2006-2009.
The World Nuclear Association (WNA) is the international organization that promotes nuclear power and supports the companies that comprise the global nuclear industry. Its members come from all parts of the nuclear fuel cycle, including uranium mining, uranium conversion, uranium enrichment, nuclear fuel fabrication, plant manufacture, transport, and the disposition of used nuclear fuel as well as electricity generation itself.
The African Society for Bioinformatics and Computational Biology (ASBCB) is a non-profit professional association dedicated to the advancement of bioinformatics and computational biology in Africa. Transformed from the African Bioinformatics Network (ABioNET), ASBCB was established in February 2004 at a meeting in Cape Town, South Africa. The Society serves as an international forum and resource devoted to developing competence and expertise in bioinformatics and computational biology in Africa. It complements its activities with those of other international and national societies, associations and institutions, public and private, that have similar aims. It also promotes the standing of African bioinformatics and computational biology in the global arena through liaison and cooperation with other international bodies. It is an affiliated regional group of the International Society for Computational Biology (ISCB).
Groundwater models are computer models of groundwater flow systems, and are used by hydrogeologists. Groundwater models are used to simulate and predict aquifer conditions.
The International Association of Hydrological Sciences (IAHS) is a non-profit non-governmental scientific organisation committed to serving the science of hydrology and the worldwide community of hydrologists. The IAHS was established in 1922, and presently claims a membership in excess of 8600 with members in almost 200 countries.
The Black Tiger Spring (Chinese: 黑虎泉; pinyin: Hēi Hǔ Quán) is a culturally significant artesian karst spring located in the city of Jinan, Shandong Province, China. The spring is ranked as the second most significant among the 72 named springs in Jinan. The water of spring stems from moderately-deep circulation and emerges from a water-filled limestone cave in a steep cliff. From the mouth of the cave, the water is funneled to flow out of the mouths of three ornamental stone-carved tiger heads into a square-shaped spring pool. From there it runs into the old city moat, next to which the spring is located. According to the tradition, there was a black rock lying in front of the cave in ancient time. The name of the spring is said to be derived from the shape and color of the rock, which resembled a black tiger, and the sound of the water gushing past the rock being reminiscent of the roar of a tiger. The ancient layout of the spring is described in a poem by the Ming Dynasty poet, Yan Bizeng.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field work is an important component of geology, although many subdisciplines incorporate laboratory work.
The following outline is provided as an overview of and topical guide to hydrology:
Leo Picard, was an Israeli geologist and an expert in the field of hydrogeology.
Paul Younger, DL, FREng, FRSE, FGS, FIChemE, FICE was a British hydrogeologist, environmental engineer and writer. He worked both on water resources, and water pollution.
Oscar Edward Meinzer was an American hydrogeologist who has been called the "father of modern groundwater hydrology". He was awarded the William Bowie Medal in 1943. The O. E. Meinzer award is named for him. He collaborated with Norah Dowell Stearns, one of the first women hydrogeologists.
Dr. Jean Marie Bahr is a hydrogeologist who examines how the physical and chemical composition of groundwater and how that controls the mass transportation of groundwater. She currently is an Emeritus Professor at the University of Wisconsin Madison in the department of geosciences.
Holly Michael is an American hydrogeologist and Associate Professor of geology at the University of Delaware's College of Earth, Ocean, and Environment.
Groundwater in Nigeria is widely used for domestic, agricultural, and industrial supplies. The Joint Monitoring Programme for Water Supply and Sanitation estimate that in 2018 60% of the total population were dependent on groundwater point sources for their main drinking water source: 73% in rural areas and 45% in urban areas. The cities of Calabar and Port Harcourt are totally dependent on groundwater for their water supply.
