József Tóth (hydrogeologist)

József Tóth (hydrogeologist) is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand József Tóth (hydrogeologist) rather than just read about it. In short: József Tóth (June 22, 1933 – July 3, 2026) was a Hungarian-born hydrogeologist and academic who was Professor Emeritus of the University of Alberta in Canada, and Honorary Professor at the Eötvös Loránd University in Budapest, Hungary. Background József Tóth was born in Békés, Hungary on June 22, 1933.

Key takeaways

József Tóth (hydrogeologist) belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect József Tóth (hydrogeologist) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of József Tóth (hydrogeologist) from memory before moving on to harder problems.

Reference excerpt

József Tóth (June 22, 1933 – July 3, 2026) was a Hungarian-born hydrogeologist and academic who was Professor Emeritus of the University of Alberta in Canada, and Honorary Professor at the Eötvös Loránd University in Budapest, Hungary.

Background József Tóth was born in Békés, Hungary on June 22, 1933. In 1952, he was admitted to the University of Sopron as a student of geophysics. He took part in the Hungarian Revolution of 1956, after the fall of which he fled to Austria and then the Netherlands. He resumed his studies at Utrecht University, and in 1960 emigrated to the Canadian province of Alberta with his wife and two children. In 1965, he received his doctorate in Utrecht. He died on July 3, 2026, at the age of 93.

Career Although he was employed as a geophysicist at the Research Council of Alberta, he soon had to work as a groundwater consultant in Hydrogeology. Working from M.K. Hubbert's 1940 paper "The theory of ground-water motion", Tóth solved the Laplace equation for a "unit basin" geometry. Superposing a sinusoidal constant head surface on the unit basin "resulted in the concept of composite flow patterns", referred to as "hierarchically nested flow systems." His theory of regional groundwater flow is discussed in most hydrogeology textbooks, such as Fetter, Hornberger et al., Deming, and Freeze and Cherry's Groundwater, the cover of which prominently featured his regional flow diagram. He rose to be the Head of the Groundwater Department at the Research Council. He also taught hydrogeology courses at the University of Alberta and University of Calgary and was a full professor at the University of Alberta (Rostron, Benjamin J, p. 205-206 in Deming, 2002. Among his more than a hundred publications of international influence based on his theory, several of his studies cover special fields, such as: underground storage of highly radioactive waste; formation and improvement of saline soils; hydrocarbon and uranium ore exploration; soil and rock mechanics; and formation of wetlands.

Worked examples

Example 1 — a first encounter with József Tóth (hydrogeologist)

Start with the simplest possible case. Write down what József Tóth (hydrogeologist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to József Tóth (hydrogeologist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about József Tóth (hydrogeologist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of József Tóth (hydrogeologist)

In research: József Tóth (hydrogeologist) appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses József Tóth (hydrogeologist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: József Tóth (hydrogeologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 births, 2026 deaths, 20th-century Canadian scientists, so understanding it makes those chapters shorter.
In everyday life: Look for József Tóth (hydrogeologist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
