Souris–Red–Rainy water resource region

Souris–Red–Rainy water resource region 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 Souris–Red–Rainy water resource region rather than just read about it. In short: The Souris–Red–Rainy region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. These geographic areas contain either the drainage area of a major river, or the combined drainage areas of a series of rivers.

Key takeaways

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

Reference excerpt

The Souris–Red–Rainy region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. These geographic areas contain either the drainage area of a major river, or the combined drainage areas of a series of rivers. The Souris–Red–Rainy Region, which is listed with a 2-digit hydrologic unit code (HUC) of 09, has an approximate size of 90,759 square miles (235,060 square kilometers), and consists of 3 subregions, which are listed with the 4-digit HUC codes of 0901 through 0903. This region includes the drainage within the United States of the Lake of the Woods and the Rainy, Red, and Souris River Basins that ultimately discharges into Lake Winnipeg and Hudson Bay. Includes parts of Minnesota, North Dakota, and South Dakota.

Worked examples

Example 1 — a first encounter with Souris–Red–Rainy water resource region

Start with the simplest possible case. Write down what Souris–Red–Rainy water resource region 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 Souris–Red–Rainy water resource region 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 Souris–Red–Rainy water resource region 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 Souris–Red–Rainy water resource region

In research: Souris–Red–Rainy water resource region 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 Souris–Red–Rainy water resource region 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: Souris–Red–Rainy water resource region is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drainage basins, Regions of the United States, Water resource regions, so understanding it makes those chapters shorter.
In everyday life: Look for Souris–Red–Rainy water resource region 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.
