Teufelsteich

Teufelsteich is a engineering 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 Teufelsteich rather than just read about it. In short: The Teufelsteich was one of the oldest reservoirs in the Harz Mountains of central Germany. It was built in 1697 near Harzgerode and Quedlinburg (in the present state of Saxony-Anhalt) for mining purposes.

Key takeaways

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

Reference excerpt

The Teufelsteich was one of the oldest reservoirs in the Harz Mountains of central Germany. It was built in 1697 near Harzgerode and Quedlinburg (in the present state of Saxony-Anhalt) for mining purposes. In 1837/38 it was raised to support silver mining. The Teufelsteich was first linked to the Lower Harz Pond and Ditch System in 1903/04. The Kochsgraben was extended for the last time and it now ended in the catchment area of the Teufelsteich, the Siebengrund bottom. This extension was called the Siebengründer Graben; at the same time the section to Neudorf was drained dry. The Teufelsteich was now supplied with water from the Lude stream and the Rödelbachgraben along with the nearby mining ponds of the Fürstenteich and the Silberhütter Pochwerksteich. In 1947 the pond was used for the first time to supply drinking water. In 1985 the embankment had to be completely replaced. To do this a new dam was built 30 m below the old one and the old dam removed. The new, higher dam consists of a shale body with a clay core in the centre. The retaining capacity of the new dam is around 203,000 m³ greater. The reservoir now has new facilities such as a spillway, a bottom outlet, a glory hole spillway (Entnahmeturm) with service jetty, a valve house and a pump station. The impounded stream is the Teufelsgrundbach.

Worked examples

Example 1 — a first encounter with Teufelsteich

Start with the simplest possible case. Write down what Teufelsteich claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Teufelsteich 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 Teufelsteich 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 Teufelsteich

In research: Teufelsteich appears in engineering 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 Teufelsteich 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: Teufelsteich is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1697 establishments in the Holy Roman Empire, Buildings and structures completed in 1697, Lower Harz Pond and Ditch System, so understanding it makes those chapters shorter.
In everyday life: Look for Teufelsteich 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.

Frequently asked questions

What is Teufelsteich in simple terms?

Why does Teufelsteich matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Teufelsteich?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
