Haarlemmertrekvaart

Haarlemmertrekvaart is a engineering 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 Haarlemmertrekvaart rather than just read about it. In short: The Haarlemmertrekvaart [ˌhaːrlɛmərˈtrɛkfaːrt] (Haarlem's Tow-Canal) is a canal between Amsterdam and Haarlem in the province of North Holland, the Netherlands. It was dug in 1631, making it the oldest tow-canal in Holland.

Key takeaways

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

Reference excerpt

The Haarlemmertrekvaart [ˌhaːrlɛmərˈtrɛkfaːrt] (Haarlem's Tow-Canal) is a canal between Amsterdam and Haarlem in the province of North Holland, the Netherlands. It was dug in 1631, making it the oldest tow-canal in Holland. Travel on such canals was historically done by barges (or trekschuit in Dutch) which were towed by animals (and sometimes by man-power) on a path along the canal's edge (towpath).

History

Until the beginning of the 17th century, the primary waterway between Amsterdam and Haarlem was the IJ, a bay of the Zuiderzee. The land route was over the twisty dike along this bay. In 1631 construction began and the canal was dug in a virtually straight line to guarantee the shortest route. It shortened the waterway from Haarlem to Amsterdam considerably. Until that time, boats needed to travel up the Spaarne river to pass the narrow sluice gate at Spaarndam, to reach the IJ. Similarly, the towpath shortened the route considerably for land traffic. Prior to this route, coaches traveling by land would leave Haarlem over the Oude Weg up to the Liede, where they would cross at Penningsveer (a ferry for a penny), to Spaarnwoude and along the IJdijk (on older maps, Spaarndammerdijk) to Amsterdam. The first trekschuit 'sailed' in 1632 between Amsterdam and Haarlem, and could carry 30 passengers. Because of the sluice gate between the Haarlem Lake and the IJ, the canal was not continuous. The passengers needed to disembark and change boats at this point, which was halfway, and where the town of Halfweg (meaning "halfway") formed. Commercial freight was not allowed to use the canal, and a complicated tax system on water transport kept the trekschuit system a stable means of passenger transport for centuries. The success of the Haarlemmertrekvaart led to the extension of the canal from Haarlem to Leiden by means of the Leidsevaart in 1657. When the Haarlem Lake became a polder in 1852, the former sluice gate became a steam-driven drainage pump, which is now a museum. A railway parallel to the canal was built in 1839 which rendered passenger transport on the Haarlemmertrekvaart obsolete. While there is no longer any shipping on the canal, it is still being used for water management.

Worked examples

Example 1 — a first encounter with Haarlemmertrekvaart

Start with the simplest possible case. Write down what Haarlemmertrekvaart claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Haarlemmertrekvaart 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 Haarlemmertrekvaart 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 Haarlemmertrekvaart

In research: Haarlemmertrekvaart appears in engineering 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 Haarlemmertrekvaart 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: Haarlemmertrekvaart is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1631 establishments in the Dutch Republic, Buildings and structures completed in 1631, Canals in North Holland, so understanding it makes those chapters shorter.
In everyday life: Look for Haarlemmertrekvaart 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.
