Proston Weir

Proston Weir 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 Proston Weir rather than just read about it. In short: The Proston Weir is a small weir located on Stuart River between the localities of Proston and Okeden in the South Burnett Region of Queensland, Australia. The weir is located 5 kilometres (3.1 mi) southwest of the town of Proston and downriver from the Gordonbrook Dam and upstream from the confluence with the Boyne River.

Key takeaways

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

Reference excerpt

The Proston Weir is a small weir located on Stuart River between the localities of Proston and Okeden in the South Burnett Region of Queensland, Australia. The weir is located 5 kilometres (3.1 mi) southwest of the town of Proston and downriver from the Gordonbrook Dam and upstream from the confluence with the Boyne River.

Overview Construction of the mass concrete gravity structure commenced in 1965 and concluded in c. 1966. The purpose of the weir was to supply water for agriculture including stock and limited irrigation. The weir incorporates a 1.5-metre-high (5 ft) water-inflated rubber dam for a moveable crest which automatically adjusts itself to permit flood flows to pass downriver without causing excessive increase in the water level and to minimise siltation in the storage. Estimates of the storage capacity range from 307 megalitres (249 acre⋅ft) to 370 megalitres (300 acre⋅ft).

Recreation There are no picnic or toilet facilities adjacent to the weir. Recreational fishing is permitted, but no power boating is allowed. When the weir overflows the current becomes strong 200 metres (660 ft) upstream of the dam wall. As there aren't any safety barriers on the wall, swimming or kayaking on the weir after heavy rain is considered extremely dangerous.

Worked examples

Example 1 — a first encounter with Proston Weir

Start with the simplest possible case. Write down what Proston Weir 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 Proston Weir 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 Proston Weir 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 Proston Weir

In research: Proston Weir 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 Proston Weir 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: Proston Weir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s establishments in Australia, Dams completed in the 1960s, Dams in Queensland, so understanding it makes those chapters shorter.
In everyday life: Look for Proston Weir 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.
