List of drainage basins of Australia

List of drainage basins of Australia 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 List of drainage basins of Australia rather than just read about it. In short: A drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a converging point such as a river mouth, or into a water body such as a lake or the ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels and is separated from adjacent basins by a drainage divide.

Key takeaways

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

Reference excerpt

A drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a converging point such as a river mouth, or into a water body such as a lake or the ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels and is separated from adjacent basins by a drainage divide. In Australia, major drainage basins are coded by hierarchy within the National Catchment Boundaries (NCB) dataset, with primary drainage basins attributed Level 1 and smaller river catchment subdivisions attributed Level 2. Beyond that, minor river and creek watersheds are ranked by the Pfafstetter Coding System. This article deals with surface water rather than groundwater basins, such as the Great Artesian Basin. Australia has twelve distinguished NCB Level 1 drainage divisions or thirteen after splitting the South East Coast division at the New South Wales–Victoria border as defined by the Australian Water Resources Assessment 2012, a hydrological survey conducted by the Bureau of Meteorology. Runoff from these divisions generally flows into the Pacific Ocean, the Indian Ocean, the Southern Ocean and Lake Eyre.

List of NCB Level 1 drainage basins

A ^ New drainage basin codes assigned by the Bureau of Meteorology in 2010. Previous codes were labelled using Roman Numerals. See [1] for details. B ^ Long term average from July 1911 to June 2010 C ^ The obsolete Australia River Basins 1997 survey listed the Bulloo-Bancannia drainage basin as a separate division, but has now been combined with the Lake Eyre Basin. D ^ Known in Queensland as Gulf Basin

Worked examples

Example 1 — a first encounter with List of drainage basins of Australia

Start with the simplest possible case. Write down what List of drainage basins of Australia 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 List of drainage basins of Australia 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 List of drainage basins of Australia 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 List of drainage basins of Australia

In research: List of drainage basins of Australia 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 List of drainage basins of Australia 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: List of drainage basins of Australia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drainage basins of Australia, Lists of drainage basins, Lists of landforms of Australia, so understanding it makes those chapters shorter.
In everyday life: Look for List of drainage basins of Australia 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.
