The Thukela Water Management Area, whose water source is in the Drakensberg region, includes the Buffalo River (BR) catchment as a sub-catchment.
The current study's case study catchment was the Buffalo River in the Eastern Cape of South Africa. This river has few tributaries, a maximum order of 4 (Strahler, 1957), and is rather short (125 km from headwaters to sea). Although it rains throughout the year, the majority of it falls in the summer and there is a sharp gradient in rainfall between the upper (1500-2000 mm) and middle (500- 625 mm) reaches. The river has four impoundments: Maden and Rooikrans dams in the top catchment, the larger Laing Dam and Bridle Drift Dam in the middle and lower catchments, and Maden and Rooikrans dams in the lower catchment.

Paragraph 4: What is the relationship between Climate change and the regularity of droughts
Answer:How climate change contributes to drought
Explanation:
Warmer temperatures enhance evaporation, which reduces surface water and dries out soils and vegetation. This makes periods with low precipitation drier than they would be in cooler conditions. Climate change is also altering the timing of water availability.
What conditions would are more hazardous to the coast, a hurricane surge during high tide or a tsunami. Why one would be more hazardous than the other or both are similarly destructive?
Both a hurricane surge during high tide and a tsunami can be extremely hazardous to the coast, but there are some differences in terms of the conditions that make them more destructive.
A hurricane surge occurs when a large volume of ocean water is pushed onto shore by a hurricane or tropical storm. The severity of the surge depends on the strength of the storm and the geography of the coastline. If a hurricane surge occurs during high tide, it can lead to a much higher water level than if it occurred during low tide. This can lead to more flooding and more damage to coastal structures.
On the other hand, a tsunami is a series of ocean waves caused by an underwater earthquake, landslide, or other event. Tsunamis can be incredibly destructive because they can travel across entire ocean basins and can retain their energy as they approach shore. The severity of the tsunami depends on the size of the earthquake or event that caused it, the distance from the event to the coast, and the geography of the coastline. In general, a tsunami can be much more powerful and destructive than a hurricane surge.
Therefore, both a hurricane surge during high tide and a tsunami can be hazardous to the coast, but a tsunami can be more destructive due to its potential for greater power and reach.
Why is specialization a common result of free trade?
A. Worker safety agreements encourage production that uses skilled
labor.
B. Competition encourages countries to specialize in what they do
best.
C. Trade agreements determine what each country must produce.
D. Loss of import tax revenues forces countries to limit what they
manufacture.
Free trade frequently leads to specialisation because it encourages nations to concentrate on providing the commodities and services that they are best fitted to produce. Option B. B. Competition encourages countries to specialize in what they do best. is correct.
Countries might specialise in the production of goods and services where they have a comparative advantage, i.e., where they can produce at a lower opportunity cost relative to other countries, when they can trade freely with one another.
For instance, a nation with an abundance of natural resources can be known for manufacturing raw materials, but a nation with a highly educated workforce might be known for generating high-tech goods. Specialisation in certain fields boosts productivity and efficiency, which ultimately lowers costs for consumers. All free trade participants can gain from this.
As a result, specialisation is crucial to free trade since it enables nations to concentrate on their advantages and increase their economic production.

describe that raw materials from farming and fishery help to generate revenues
Answer:
Explanation:
Raw materials from farming and fishery are essential for many industries, including food and beverage production, textiles, pharmaceuticals, and cosmetics. These raw materials include crops, livestock, and fish that are grown, raised, or caught by farmers and fishermen.
Farming and fishery industries provide the raw materials that are used to produce a wide variety of products, which in turn generate revenue. For example, crops like wheat, corn, and rice are used to make flour, cereals, and other food products, which are sold to consumers and generate revenue for the companies that produce them. Livestock such as cows, pigs, and chickens are raised for meat, dairy, and egg production, which also generates revenue.
Similarly, fish caught by fishermen are used to produce a wide range of products such as canned fish, fish oil, and fish meal, which are used in animal feed, pet food, and other products. These products generate revenue for the companies that produce them.
Moreover, raw materials from farming and fishery also help to support local and national economies. For example, in many countries, agriculture and fishing are major sources of employment and income for rural communities. The sale of raw materials from farming and fishery generates revenue for these communities and contributes to the growth of the local economy.
Overall, the raw materials from farming and fishery play a crucial role in generating revenue for industries and supporting local and national economies.
Look at the description of the Sherburne. How was the distance to/ from the shore of the sea changing in the area as the Sherburne was being deposited?
Why are there no fossil ferns or primitive pine trees
Answer from your tutor:
The Sherburne formation is starting to become sandier the closer you get to the top because the shore is starting to transition to sandstone.
How did the distance to/from the shore change as Sherburne was deposited?The Sherburne formation refers to sequence of sedimentary rocks that was deposited in the Late Cretaceous period in what is now Montana and Wyoming which is thought to have been deposited in a shallow marine environment with the shoreline fluctuating over time.
As the Sherburne was being deposited, the distance to/from the shore of the sea was changing in the area. At the bottom of the formation, the sediment is composed of finer-grained rocks such as shale and mudstone which indicate a more offshore environment.
But as you move up the formation, the sediment becomes coarser with the sandstone and conglomerate becoming more prevalent which suggests that the shoreline was moving closer and the area was becoming shallower.

background information about area of study with poor service delivery: explain where in Polokwane the study area is located
The study area with poor service delivery is located in the city of Polokwane and Polokwane city is located in Limpopo Province of South Africa
The city is the capital of the province and is one of the largest urban areas in the region.
Polokwane has a diverse population, with a mix of different ethnicities and cultures.
Specifically, it is situated in one of the low-income suburbs in the southern part of the city.
This area is characterized by informal settlements, high unemployment rates, and inadequate service delivery.
In recent years, the area has experienced significant population growth due to migration from rural areas and other parts of the country.
This has put pressure on the existing infrastructure, leading to a range of service delivery challenges.
Residents in the area struggle with issues such as poor sanitation, inadequate housing, limited access to healthcare, and unreliable public transport.
The local government has implemented various initiatives aimed at improving service delivery in the area, such as the construction of new housing developments, upgrading of road networks, and provision of basic services such as water and electricity. However, these efforts have been inadequate to meet the needs of the growing population, and much more needs to be done to address the service delivery challenges in the area.
