Kouhrang 3 Dam

Kouhrang 3 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 Kouhrang 3 Dam rather than just read about it. In short: The Kouhrang 3 Dam (سد کوهرنگ ۳, also known as Birgan dam بیرگان) is an arch dam currently under construction on the Kouhrang River in Chaharmahal and Bakhtiari province, Iran. It is located about 12 km (7.5 mi) northwest of Dashtak.

Key takeaways

Kouhrang 3 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 Kouhrang 3 Dam to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kouhrang 3 Dam from memory before moving on to harder problems.

Reference excerpt

The Kouhrang 3 Dam (سد کوهرنگ ۳, also known as Birgan dam بیرگان) is an arch dam currently under construction on the Kouhrang River in Chaharmahal and Bakhtiari province, Iran. It is located about 12 km (7.5 mi) northwest of Dashtak. The purpose of the dam is water supply and river regulation. Upstream of the dam will be the intake for the 23 km (14 mi) Kouhrang 3 Tunnel which will transfer water northeast to the Zayandeh River for use in major cities like Isfahan. Sabir Co. was awarded the contract for the dam's construction in February 2011 and construction began that same year. The diversion tunnels for the dam were completed in March 2013. The project was scheduled for completed in 2015. As of July 2017, the project was not yet complete, though the tunnel was considered 97% finished, and newly allocated funds were expected to allow imminent completion. It is claimed that construction of the tunnel in difficult geological conditions has led to drying up of springs, and the estimated transfer volume has been reduced from 270–300 to 40–130 million cubic metres per year.

Worked examples

Example 1 — a first encounter with Kouhrang 3 Dam

Start with the simplest possible case. Write down what Kouhrang 3 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 Kouhrang 3 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 Kouhrang 3 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 Kouhrang 3 Dam

In research: Kouhrang 3 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 Kouhrang 3 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: Kouhrang 3 Dam is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arch dams, Dams in Chaharmahal and Bakhtiari Province, Dams under construction, so understanding it makes those chapters shorter.
In everyday life: Look for Kouhrang 3 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.
