Schwyll Aquifer

Schwyll Aquifer is a 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 Schwyll Aquifer rather than just read about it. In short: Schwyll Aquifer (pronounced 'Shwill') was historically known as 'the Great Spring of Glamorgan'. Welsh Water uses the resurgence at the Schwyll Spring near Ewenny in the Vale of Glamorgan as the main source of water for the Bridgend area.

Key takeaways

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

Reference excerpt

Schwyll Aquifer (pronounced 'Shwill') was historically known as 'the Great Spring of Glamorgan'. Welsh Water uses the resurgence at the Schwyll Spring near Ewenny in the Vale of Glamorgan as the main source of water for the Bridgend area. Now functioning as a backup supply, it has a number of associated source protection zones policed by Natural Resources Wales. The aquifer is an underground layer of water-bearing permeable rock. In this case, it consists of an underground waterway in the carboniferous limestone. Due to the delay between local heavy rain and discoloration of the water at the spring, it is believed that the origination is 20 miles away. This would locate the main source in the limestone of the southern edge of the Brecon Beacons. The lack of an access at the rising hinders exploration of the cave system. The only known point of access is at the pumping shaft of the extraction plant at Schwyll. The system was explored by cave divers in 1998 to 440 metres from the shaft. At 400 metres, a large cavern was discovered containing bones which were identified as horse. The bones were submitted for dating. The outflow of the spring is far larger than any other spring in Wales and greater than that from the Wookey Hole or the Cheddar Gorge risings in England.

Worked examples

Example 1 — a first encounter with Schwyll Aquifer

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

In research: Schwyll Aquifer appears in 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 Schwyll Aquifer 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: Schwyll Aquifer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aquifers, Bodies of water of the Vale of Glamorgan, Glamorgan geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Schwyll Aquifer 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.
