Suiken Embankment

Suiken Embankment 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 Suiken Embankment rather than just read about it. In short: The Suiken Embantment (水軒堤防, Suiken teibō) is an Edo period levee located in the Nishihama neighborhood of the city of Wakayama, Wakayama Prefecture, in the Kansai region of Japan. The site was designated a National Historic Site of Japan in 2019.

Key takeaways

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

Reference excerpt

The Suiken Embantment (水軒堤防, Suiken teibō) is an Edo period levee located in the Nishihama neighborhood of the city of Wakayama, Wakayama Prefecture, in the Kansai region of Japan. The site was designated a National Historic Site of Japan in 2019.

Overview The Suiken Levee is located on the south bank of the mouth of the Kinokawa River, which flows through the northern part of Wakayama Prefecture. It forms a seawall and breakwater and extends for 2.6 kilometers, of which approximately 1.5 kilometers are covered by the National Historic Site designation. The levee consists of three portions. The middle portion (approximately 960 meters) consists of a stone embankment with a trapezoidal cross section, a clay embankment behind it, and stone paving in front. The stones are ashlars of local Izumi sandstone. The double structure of the stone embankment and the earthen embankment was designed to be able to withstand the load caused by waves, The southern portion consists only of an earthen embankment, and is approximately 280 meters long, and the northern portion is largely a natural levee, with a length of approximately 1370 meters. The levee had a height of between 3.7 and 4.4 meters and a width of 27 meters or more. There are few historical records pertaining to the construction of this levee, and it has long been attributed to Asahina Danzaemon, a retainer of Kishu Domain in the early 17th century. However, archaeological excavations from 2004 to 2009 have found that it was constructed around the latter half of the 18th century. Much of the levee is buried under sand which has accumulated over time A part of the excavated portion has been preserved at the Suiken Park, near Suiken Station on the Nankai Electric Railway Wakayamako Line.

Worked examples

Example 1 — a first encounter with Suiken Embankment

Start with the simplest possible case. Write down what Suiken Embankment 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 Suiken Embankment 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 Suiken Embankment 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 Suiken Embankment

In research: Suiken Embankment 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 Suiken Embankment 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: Suiken Embankment is common in secondary-school and first-year university syllabi. It links to neighbouring topics 18th-century establishments in Japan, Historic Sites of Japan, History of Wakayama Prefecture, so understanding it makes those chapters shorter.
In everyday life: Look for Suiken Embankment 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.
