Gouina Hydroelectric Plant

Gouina Hydroelectric Plant 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 Gouina Hydroelectric Plant rather than just read about it. In short: The Gouina Hydroelectric Plant (French: Centrale hydroélectrique de Gouina) is a run-of-the-river-type hydroelectric installation on Gouina Falls along the Senegal River in Mali. It is located about 18 km (11 mi) southeast of Diamou in the Kayes Region.

Key takeaways

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

Reference excerpt

The Gouina Hydroelectric Plant (French: Centrale hydroélectrique de Gouina) is a run-of-the-river-type hydroelectric installation on Gouina Falls along the Senegal River in Mali. It is located about 18 km (11 mi) southeast of Diamou in the Kayes Region. It is the fourth project of the Senegal River Basin Development Authority and its ground-breaking ceremony on 17 December 2013 was attended by the heads of state of each member country. Mauritanian President Mohamed Ould Abdel Aziz laid the foundation stone. Preliminary construction had been suspended due to the 2012 Malian coup d'état and subsequent Northern Mali conflict. The plant was inaugurated by the Malian Prime Minister Abdoulaye Maïga in December 2022. It cost US$329 million and the 280 km (170 mi) of transmission lines cost US$65 million. The project received 85 percent of its funding from the Exim Bank of China along with US$1 million from the EU-Africa Infrastructure Trust Fund and US$1.4 million from the International Development Association and European Investment Bank. It has an installed capacity of 140 megawatts (190,000 hp) and will use the outflows of the Manantali Dam upstream to regulation water flow into the plant. A 1,230 m (4,040 ft) long weir just above the water fall directs water into a channel which will feed the power house just downstream of the falls. The power house contains three 46.6 MW Kaplan turbine-generators. The difference in elevation the water fall and weir provides a hydraulic head (water drop) of 22.5 m (74 ft).

Worked examples

Example 1 — a first encounter with Gouina Hydroelectric Plant

Start with the simplest possible case. Write down what Gouina Hydroelectric Plant 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 Gouina Hydroelectric Plant 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 Gouina Hydroelectric Plant 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 Gouina Hydroelectric Plant

In research: Gouina Hydroelectric Plant 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 Gouina Hydroelectric Plant 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: Gouina Hydroelectric Plant is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dams in Mali, Dams on the Senegal River, Dams under construction, so understanding it makes those chapters shorter.
In everyday life: Look for Gouina Hydroelectric Plant 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.
