Reference excerpt

The Napa River flood of 1986 is considered by many to be the worst flood experienced by Napa, California, United States, during the 20th century. Twenty inches of rain fell in a 48-hour period; 7,000 people were evacuated, 250 homes were destroyed and another 2,500 were damaged. Three people died, and estimated damages reached $100 million. Following the flood, residents expressed a renewed urgency to mitigate flooding caused by winter storms, which created obstacles that slowed the flow of the river on its course to San Francisco Bay. Since the flood, the Napa County Flood Control and Water Conservation District has worked to manage floods through the Napa River Flood Project. Another flood of lesser proportions occurred on December 31, 2005, after over a week of rain. Smaller floods also occurred in 1995 and 1997.

Worked examples

Example 1 — a first encounter with Napa River flood of 1986

Start with the simplest possible case. Write down what Napa River flood of 1986 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 Napa River flood of 1986 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 Napa River flood of 1986 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 Napa River flood of 1986

In research: Napa River flood of 1986 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 Napa River flood of 1986 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: Napa River flood of 1986 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s floods, 1980s floods in the United States, 1986 in California, so understanding it makes those chapters shorter.
In everyday life: Look for Napa River flood of 1986 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.
