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 drainage basin sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, 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.
Hydrogeology is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust. The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably.
William Bernard Robinson King was a British geologist.
The International Association of Hydrogeologists (IAH) is a scientific and educational organisation whose aims are to promote research into and understanding of the proper management and protection of groundwater for the common good throughout the world.
Timothy J. Callahan is an associate professor of geology and environmental geosciences at the College of Charleston in South Carolina. He is director of the college's Master of Environmental Studies program and has interests in hydrogeology, wetlands and water resources.
John M. (Jack) Sharp, Jr. is Dave P. Carlton Professor of Geology at The University of Texas at Austin. He was the president of the Geological Society of America from June 2007 to June 2008.
The International Association of Hydrological Sciences (IAHS) is a non-profit, non-governmental scientific organization 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 9,000 with members in over 150 countries.
The following outline is provided as an overview of and topical guide to hydrology:
Paul Younger 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.
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.
Shirley Jean Dreiss (1949–1993) was an American scientist working in the fields of hydrology and hydrogeology. After gaining her PhD from Stanford University, she joined the faculty of the University of California at Santa Cruz, where she became Professor and Chair of the Department of Earth Sciences. She made important contributions to the understanding of water flow through karst aquifers and fluid flow in subduction zones. At the time of her early death in a car accident, she was studying the groundwater system of Mono Lake in California. She was awarded the Birdsall Distinguished Lectureship from the Geological Society of America, which was renamed the Birdsall-Dreiss Distinguished Lectureship after her death.
Holly Michael is an American hydrogeologist and Associate Professor of geology at the University of Delaware's College of Earth, Ocean, and Environment.
Norah Dowell Stearns (1891–Unknown) was an American hydrogeologist from Providence, Rhode Island. She was one of the earliest-known women to contribute to hydrogeology.
Audrey Hucks Sawyer is an American hydrogeologist and Assistant Professor of Earth Science at Ohio State University. Her work has focused on quantifying the role of groundwater - surface water interactions in transporting nutrients, contaminants, and heat in rivers and coastal settings. Sawyer has won multiple awards, including the National Science Foundation CAREER Award in 2018 and the Kohout Early Career Award in 2016.
Abhijit Mukherjee is an Indian professor, scientist and currently Professor of Geology and Geophysics and the School of Environmental Science and Engineering of IIT Kharagpur. He has been selected for Shanti Swarup Bhatnagar Prize for Science and Technology in 2020 in the field of Earth Atmosphere Ocean and Planetary Sciences.
Bridget R. Scanlon is an Irish and American hydrogeologist known for her work on groundwater depletion and groundwater recharging, and of the effects of climate change and land usage patterns on groundwater. She is a senior research scientist in the Bureau of Economic Geology at the University of Texas at Austin, where she is head of the Sustainable Water Resources Program. Her research has included the use of GRACE satellite data to compare drought conditions in Texas and California.
József Tóth is a hydrogeologist and Professor Emeritus of the University of Alberta in Canada and Honorary Professor at the Eötvös Loránd University in Budapest, Hungary.
Donald Ira Siegel is the emeritus Laura J. and L. Douglas Meredith Professor in the department of Earth Science at Syracuse University. He served as the president of the Geological Society of America from July 2019 until June 2020. Siegel is known for his work in wetland geochemistry and hydrogeology.
Beth L. Parker is a hydrogeologist and professor at the University of Guelph who has made exceptional contributions to the science and practice of Contaminant Hydrogeology and the protection of groundwater from contamination, that have been adopted internationally to protect water supplies in Guelph and many other communities.
