Reborn as a police officer in South Africa

The exploration team camped in the mountains at night, and Aric stewed a pot of snake soup, which comforted Dennis' injured soul to the greatest extent.

 When Gardner's student Xiao Hua treated Dennis' blisters on his feet, Dennis's painful wails could be heard throughout the canyon.

"It's not a big problem. After the blisters burst, they will turn into cocoons and you won't suffer this kind of pain again in the future." Xiao Hua said nicely. He would definitely suffer in these two days.

“Thank you Xiao, are you a doctor?” Dennis was still very grateful to Xiao Hua. He took out a cigar from his pocket and handed it to Xiao Hua.

Xiao Hua did not refuse. He took the hand and sent it to Gardner. Then he came back and explained: "No, I am a student of Professor Gardner. Wilderness first aid is also part of our courses. You know, field work

, we often encounter various accidents, and without professional doctors, we can only save ourselves."

“It’s really not easy. Your work is very hard. The federal government should give each of you a medal.” Dennis deeply understood the hardship of field work. The development of Southern Africa is based on the silent contributions of countless people.

"I don't think it's hard. This is my own choice. It's my hobby. While working, I can also travel and see the magnificent scenery of nature. What could be happier than this?" Xiao Hua is really not Versailles.

Unlike other people who carried as little as possible, Xiao Hua carried a huge backpack and a bulky camera, taking many photos along the way.

"I wish you success in your studies. You will become an excellent geologist and maybe a photographer. I look forward to seeing an exhibition of your photography works in Pretoria one day." Dennis

I'm very happy, not only for Xiao Hua, but also for southern Africa.

Southern Africa is indeed lucky to have such outstanding, pragmatic and dedicated young people.

“I have already held a photo exhibition at Nyasaland University, and the results were pretty good. The Nyasaland Photography Association accepted me as a member, and I have gained a lot from it.” Xiao Hua is a cheerful and sunny young man.

 There was no talking all night. The next morning, after a simple breakfast, Xiao Hua did not forget to bring the cans and put out all the bonfires when setting off to completely eliminate the hidden dangers.

 Four hours later, the group finally saw the Ohrabis Falls.

From a distance, you can see the water mist that is more than 100 meters high, as well as the rainbow formed by the refraction of the water mist. This is a beautiful scenery unique to waterfalls. Therefore, Ohrabis Falls is also called the "Rainbow Falls".

The total drop of Ohrabis Falls is 191 meters, and the depth of the pool at the bottom is more than 40 meters. During the rainy season, the width of the waterfall can reach 18 kilometers, and the flow rate is 14,000 cubic meters per second. It is a rare wonder in nature.

"Look at how beautiful and spectacular this is. If this great landscape disappears to build a reservoir, it will be a pity for all mankind." Stuart lamented, and the Ohrabis Falls is indeed very developed.

value.

"The canyon is 18 kilometers long. If we build a reservoir at the outlet of the canyon, we can maximize the use of the water resources of the Orange River." Gardner ignored Stuart. The natural landscape is indeed good, but there is no economic foundation.

If you can't even eat, who can be in the mood to appreciate the natural scenery?

"The evaporation of the Orange River is very serious. The amount of water lost due to evaporation can reach 12 times the precipitation downstream. If we build a reservoir at the mouth of the canyon, we can minimize the impact of evaporation on the water volume of the Orange River and can also meet the demand during the dry season.

Regarding the demand for water supply downstream, the Ministry of Land and Resources estimates that there are dozens of places across the Orange River suitable for building reservoirs. This is a huge project that may last for decades." Dennis sat on a simple wooden chair.

, this was made temporarily by Arik last night, otherwise Dennis might not be able to reach the Ohrabis Falls today.

The Orange River is also known as the Orange River. There are many tributaries in the upper reaches. On the right bank there are the Macallen River, the Caledon River, the Fal River, the Hronwater River, the Molopo River, the Fes Wadi River, etc.;

On the left bank are the Krai River, Sikwe River, Brak River, Hatbes River, etc.

Compared with the upper reaches, the middle and lower reaches of the Orange River have no tributaries other than seasonal rivers. This puts higher requirements on the water conservancy project of the Orange River. To ensure the water supply in the middle and lower reaches, it is necessary to ensure

There are enough reservoirs upstream.

Although there are many places suitable for building reservoirs, due to capacity and financial constraints, Southern Africa can only build up to six reservoirs on the upper reaches of the Orange River, and they must be built in batches. It is impossible to start construction at the same time, so the project will last a long time.

.

"Look at the Crocodile Bay Hydropower Station. It has been in use for more than 20 years and has generated more than 1 million pounds in value for Johannesburg and Pretoria. Hydropower does not cause huge pollution like thermal power stations. It is a one-time investment and has long-term benefits. The federal government

The requirements for environmental protection are getting higher and higher, and all states are exploring clean energy. Hydropower still has huge potential that can be explored." Gardner has ideals. Nyasaland University is not only researching more powerful hydropower units, but also

Wind power and tidal power are also being studied.

Wind power generation has been a popular project in recent years, and it is not the first of its kind at Nyasaland University. There are similar projects in Denmark, Sweden, and the United States.

Inspired by rotor technology, researchers at Nyasaland University developed a small wind power generation device and used it on windy islands and remote villages. The cost of electricity obtained is much lower than that of internal combustion engines.

The University of Nyasaland is researching a giant wind power device with a blade diameter of more than 30 meters. Once successfully developed, wind power can enter the commercial stage, which will be a huge progress in energy supply.

The history of tidal power generation is earlier than that of wind power. In 1913, Germany built a tidal power station on the coast of the North Sea, which was mankind's first tidal power station.

The principle of a tidal power station is the same as that of a hydropower station. By leaving the reservoir, seawater is stored in the reservoir during high tide and stored in the form of potential energy. Then, seawater is released at low tide, using the difference between high and low tide levels to drive the rotation of the turbine.

, drives the generator to generate electricity.

All port cities in southern Africa have great interest in this technology. Walvis Bay and Port Edward have used their own economic advantages to support the University of Nyasaland in research on tidal power generation. The progress is currently very fast. Walvis Bay already has

A tidal power station is under construction with a total installed capacity of 240,000 kilowatts and can generate about 500 million kilowatt hours of electricity every year.

 In addition to tidal power and wind power, Rock will certainly not forget nuclear power.

 Nyasaland University has begun research in nuclear physics. This is also a super project and cannot be completed overnight.

Roque is patient. Southern Africa has the funds and strength. The results are only a matter of time, as long as they can catch up with World War II.

While Gardner and Dennis were chatting, Silver was busy taking pictures. The Ohlabis Falls may disappear in the future. Silver wants to use his camera to record the Ohrabis Falls. This is one of Silver's hobbies.

.

"Don't just be busy taking pictures and forget about your work." Gardner has high requirements for Xiao Hua. During their trip, they not only have to inspect the topography of the Orange River, but also inspect the water quality of the Orange River and study how to treat it.

Soil erosion along the Orange River.

Basutoland's soil erosion is indeed very serious, which can be seen from the color of the river water. Gardner and Xiao Hua had just inspected the Victoria Falls of the Zambezi River before. Compared with the clear water of the Zambezi River, Austria's

The water of the Orange River is obviously more turbid, has a higher sand content, and the water is earthy yellow, which seriously affects the view of the Ohrabis Falls.

Xiao Hua put away his camera and jumped to the edge of the Ohrabis Falls to take some water samples. There were obviously a lot of microorganisms in the water. A layer of sand quickly fell on the bottom of the glass bottle. Gardner shook his head repeatedly.

, this kind of water quality is not good. If it is not treated, after the reservoir is built, it will have to be desilted every year.

“It is necessary to restrict livestock farming in the upper reaches of the Orange River, start afforestation along the banks, and carry out water and soil protection.” It is easy for Gardner to say it, but difficult to do it.

"This requires the cooperation of the Basutoland State Government." Dennis and Gardner whispered. Stuart couldn't hear this, otherwise Stuart would go crazy.

“We are only concerned with assessment, and the specific implementation depends on the decision of the federal government.” Gardner is not in a hurry. Basutoland must develop its economy and cooperate with the interests of the federal government.

This is just like the Rand Gold Mine. Although the Rand Gold Mine is mainly located in the Transvaal, in fact the income of the Rand Gold Mine is mainly taken away by the federal government, and the Transvaal State Government can only drink some.

Soup, otherwise Pretoria would not vigorously develop the tourism industry, and it would be great to have a comfortable gold mine.

Of course, if the tourism industry is well done, it will be an inexhaustible gold mine. This has become a consensus in southern Africa, not only in Transvaal, Nyasaland, and Rhodesia.

Countries like Pudong and other states are vigorously developing the tourism industry. Even if there are no tourists, the green mountains and green waters are more comfortable to look at than the foggy city in London.

Just as the federal government is preparing to develop the Orange and Zambezi rivers, the Nyasaland state government is also preparing to increase investment in the development of Lake Niassa. To this end, the Nyasaland state government has selected a man who has just arrived in Nyasa.

A young girl from Saran Star City has become the spokesperson for Lake Nyasa tourism. She is Greta, who has changed her name to Garbo.

Garbo came to Nyasaland Star City two months ago. With her beautiful appearance and outstanding acting talent, Garbo quickly attracted the attention of Star City Film Company, and signed a contract with Star City's largest Universal Film Company to star in Nyasaland.

The car filmed a series of car advertisements and became the spokesperson of Nyasaland Cars.

He is said to be a spokesperson, but he is actually a car model. I don’t know whether this is a blessing or a curse for Garbo.
