Silveh Dam

Silveh Dam 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 Silveh Dam rather than just read about it. In short: The Silveh Dam (Persian: سد سیلوه) is an earth-fill embankment dam on the Lavin River just downstream of the village of Silveh in Piranshahr County, West Azerbaijan Province, Iran. The primary purpose of the dam is interbasin transfer for irrigation.

Key takeaways

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

Reference excerpt

The Silveh Dam (Persian: سد سیلوه) is an earth-fill embankment dam on the Lavin River just downstream of the village of Silveh in Piranshahr County, West Azerbaijan Province, Iran. The primary purpose of the dam is interbasin transfer for irrigation. Since completion, a tunnel and canals shift water from the reservoir north to the Chaparabad area. The project essentially transfers water from the Little Zab River basin to the Lake Urmia basin in an effort to help replenish the lake and irrigate about 9,400 ha (23,000 acres) of farmland. Construction on the dam began in 2004 and it was expected to be complete by the end of 2015. The dam was effectively completed as of 2018. The village of Silveh will be flooded when the reservoir is impounded. The dam is 102 m (335 ft) above its foundation with a length of 750 m (2,460 ft). It has an uncontrolled spillway with a maximum discharge capacity of 1,040 m3/s (37,000 cu ft/s). The reservoir created by the dam will store 163,000,000 m3 (132,000 acre⋅ft) of water. Near the northeastern edge of the reservoir water will be able to enter a 841 m (2,759 ft) long tunnel which will discharge it into the opposing valley, within the Lake Urmia basin. About 121,700,000 m3 (98,700 acre⋅ft) of water will be transferred through the tunnel annually while an estimated 10,800,000 m3 (8,800 acre⋅ft) will be sent downstream to Piranshahr during the same period.

Worked examples

Example 1 — a first encounter with Silveh Dam

Start with the simplest possible case. Write down what Silveh Dam 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 Silveh Dam 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 Silveh Dam 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 Silveh Dam

In research: Silveh Dam 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 Silveh Dam 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: Silveh Dam is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dams in West Azerbaijan Province, Dams in the Tigris River basin, Earth-filled dams, so understanding it makes those chapters shorter.
In everyday life: Look for Silveh Dam 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.
