Short-term climate modeling forecasts drought for Southeast US

Many climate models focus on scenarios decades into the future, making their outcomes seem unreliable and problematic for decision-making in the immediate future. In a proactive move, researchers are using short-term forecasts ...

The dynamics of nitrogen-based fertilizers in the root zone

Nutrient contamination of groundwater as a result of nitrogen-based fertilizers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months ...

Predicting the biodiversity of rivers

Biodiversity is severely threatened both in Switzerland and worldwide, and numerous organisms are facing massive declines—particularly in freshwater ecosystems. All the species living in rivers—including fish, bacteria ...

The landscape determines how streams should be restored

The U.N. has declared the coming decade as the Decade on Ecosystem Restoration, making it particularly urgent to plan for successful restoration. Most restoration occurs in streams, and usually in short segments. Researchers ...

Hydrology

Hydrology is the study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of earth or environmental science, physical geography, geology or civil and environmental engineering.

Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage basin management and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields.

Hydrological research can inform environmental engineering, policy and planning.

The term hydrology is from Greek: ὕδωρ, hydōr, "water"; and λόγος, logos, "study".
