The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people. AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C.
The European Geosciences Union (EGU) is a non-profit international union in the fields of Earth, planetary, and space sciences whose vision is to "realise a sustainable and just future for humanity and for the planet." The organisation has headquarters in Munich (Germany). Membership is open to individuals who are professionally engaged in or associated with these fields and related studies, including students and retired seniors.
Rafael Luis Bras is a Puerto Rican civil engineer best known for his contributions in surface hydrology and hydrometeorology, including his work in soil-vegetation-atmosphere system modeling.
The James B. Macelwane Medal is awarded annually by the American Geophysical Union to three to five early career scientists. It is named after James B. Macelwane, a Jesuit priest and one of the pioneers of seismology. The medal is regarded as the highest honor for young scientists in the field of Geological and Planetary Sciences. In 1984, Mary Hudson became the first woman to receive the award.
James B. Macelwane, S.J. was a Jesuit Catholic priest and pioneering American seismologist.
The following outline is provided as an overview of and topical guide to hydrology:
Soroosh Sorooshian is an Iranian-born American civil engineer, and educator. He is a distinguished professor of civil and environmental engineering at the University of California, Irvine and currently serving as the Director of the Center for Hydrometeorology and Remote Sensing.
James W. Head III is the Louis and Elizabeth Scherck Distinguished Professor of Geological Sciences at Brown University. He studies the roles of volcanism in planetary crusts as well as the geological evolution of Mars, and has served as the investigator on many major international planetary investigation missions.
Murugesu Sivapalan is an Australian-American engineer and hydrologist of Sri Lankan Tamil origin and a world leader in the area of catchment hydrology. He is currently the Chester and Helen Siess Endowed Professor of Civil and Environmental Engineering, and professor of Geography & Geographic Information Science, at the University of Illinois, Urbana-Champaign. Sivapalan is widely recognized for his fundamental research on scale issues in hydrological modeling, his leadership of global initiatives aimed at hydrologic predictions in ungauged basins, and for his role in launching the new sub-field of socio-hydrology.
Dara Entekhabi is the Bacardi and Stockholm Water Foundations Professor in the Department of Civil and Environmental Engineering and the Department of Earth, Atmospheric and Planetary Sciences at Massachusetts Institute of Technology. His research spans a variety of topics in hydrology, including land-atmosphere interactions, surface water - groundwater interactions, data assimilation, and remote sensing.
Barbara A. Romanowicz is a French geophysicist and an expert on imaging the earth's interior.
Tuija I. Pulkkinen is a Finnish space physicist. Her primary research foci are studying the energy flow from the solar wind to the near-Earth space environment and the energy dissipation processes in the magnetosphere.
Giuliano Di Baldassarre is a Professor of Hydrology at Uppsala University and the Director of the Centre of Natural Hazards and Disaster Science, Sweden. He was awarded the American Geophysical Union Whiterspoon Lecture in 2020 and the European Geosciences Union Plinius Medal in 2021.
Marc Brendan Parlange is an American academic, recognised for his research expertise in environmental fluid mechanics and research in hydrology and climate change. His contributions primarily relate to the measurement and simulation of air movement over complex terrain, with a focus on how atmospheric turbulence dynamics influence urban, agricultural and alpine environments and wind energy. He has also been active in addressing water resources challenges and environmental change in remote communities, particularly West Africa.
Subimal Ghosh is Institute Chair Professor in the Department of Civil Engineering and Convener of the Interdisciplinary Program in Climate Studies at Indian Institute of Technology Bombay with research interests in hydrology and hydro-climatology. He obtained PhD degree in 2007 from Indian Institute of Science, Bangalore on a thesis titled "Hydrologic Impacts of Climate Change: Uncertainty Modelling", and ME degree in 2004 from the same institute.
Elizabeth A. Barnes is an American climate scientist. Barnes is best known for her work and expertise on the use of statistical methods to understand the variability of Earth's short- and long-term climate. Her work is characterized by an integration of both physics and computer science approaches. She is a Fellow of the American Geophysical Union.
Upmanu Lall is an Indian-American engineer and the Alan and Carol Silberstein Professor of Engineering at Columbia University. He serves as Director of the Columbia Water Center. Lall studies water scarcity and how to predict and mitigate floods. He was named an American Geophysical Union Fellow in 2017 and their Walter Langbein Lecturer in 2022. He was elected a fellow of the American Association for the Advancement of Science in 2018, and has received the Arid Lands Hydrology and the Ven Te Chow Awards from the American Society of Civil Engineers. In April 2021 he was named to the “Hot List of the world’s 1,000 top climate scientists” by Reuters.
Nicolas Dauphas is a planetary scientist and isotope geochemist. He is a professor of geochemistry and cosmochemistry in the Department of the Geophysical Sciences and Enrico Fermi Institute at the University of Chicago, where he was previously a Louis Block professor, being appointed to that professorship in 2016. His research focuses on isotope geochemistry and cosmochemistry. He studies the origin and evolution of planets and other objects in the solar system by analyzing the natural distributions of elements and their isotopes using mass spectrometers.
