Leidsevaart

Leidsevaart 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 Leidsevaart rather than just read about it. In short: The Leidsevaart (also known as Leidse trekvaart, Dutch for "Leiden's Pull-Canal") is a canal between the cities of Haarlem and Leiden in the Netherlands. It was dug in 1657, making it one of the oldest canals in the Netherlands.

Key takeaways

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

Reference excerpt

The Leidsevaart (also known as Leidse trekvaart, Dutch for "Leiden's Pull-Canal") is a canal between the cities of Haarlem and Leiden in the Netherlands. It was dug in 1657, making it one of the oldest canals in the Netherlands. It was the major means of transport between Leiden and Haarlem for almost two centuries until the rail connection was established in the 19th century. The original stops along the railway mirrored the toll bridges of the canal. The canal runs through or borders the municipalities of Haarlem, Heemstede, Bloemendaal, Hillegom, Noordwijkerhout, Lisse, Teylingen, Oegstgeest, and Leiden.

History

The Leidsevaart was the extension of the Haarlemmertrekvaart (Haarlem's Pull-Canal) connecting Amsterdam to Haarlem. Travel on these canals was done by trekschuit for people, and by barge for goods, which were pulled by animals (and sometimes by man-power) on a towpath along the canal's edge. It was reliable, comfortable and cheap. The speed was about 7 kilometers per hour, which was faster than walking, and more comfortable than by coach. Many wealthy Amsterdam families had summer homes along the Leidsevaart or Spaarne River, and they arrived with their heavy belongings by barge, often being pulled or sailed all the way to their door, as most summer estates had canals dug for this purpose. Even today the old canals are visible though probably too shallow for a trekschuit. The canal was kept up with toll money and taxes. Many estate owners spent money on making canal spurs to their doorstep and then had to pay taxes for fishing rights, "swan" keeping rights, or general canal use. The same was true for landowners whose lands were seized for digging the canal. They were compensated for the loss of the land strip taken up by the canal, but they had to pay for a bridge themselves. Trekschuit owners also had to pay taxes for using the canal. Taxes for traffic in people (by trekschuit) was heavier than taxes for traffic in goods (by barge). After the railway line from Leiden to Haarlem (Oude Lijn) was built, many of these extra costs made trekschuit travel unattractive and the canal quickly fell in popularity from 1842 onwards. Due to the many drawbridges along its course that are no longer in operation, the Leidsevaart is unsuitable for boat traffic nowadays and therefore has fallen mostly in disuse.

Estates along the Leidsevaart

Oud Poelgeest, home to Herman Boerhaave Keukenhof, former estate and scene of a yearly flower show in the Netherlands Huis te Vogelenzang (reachable via a rather long canal spur that continued straight when the canal approached Heemstede) The Hartekamp, home to George Clifford and famous for its Hortus Cliffortianus published by Carl Linnaeus Huis te Manpad, at the corner of the Manpadslaan and located at the toll bridge to Heemstede Leyduin, across from the Manpad Meer en Berg, at the end of the Manpad on the East side (now part of Groenendaal Park) Iepenrode, across from Groenendaal (now part of Groenendaal park) Berkenrode, across from the Haarlem toll bridge (today the location of Heemstede-Aerdenhout railway station) Alverna, a cloister across from Berkenrode

Worked examples

Example 1 — a first encounter with Leidsevaart

Start with the simplest possible case. Write down what Leidsevaart 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 Leidsevaart 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 Leidsevaart 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 Leidsevaart

In research: Leidsevaart 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 Leidsevaart 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: Leidsevaart is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1657 establishments in the Dutch Republic, Buildings and structures completed in 1657, Canals in North Holland, so understanding it makes those chapters shorter.
In everyday life: Look for Leidsevaart 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.
