Great Britain led the way in the Age of Imperialism, particularly after the Suez Canal conflict in 1882. The British intervention aimed to secure control over the canal, which was crucial for trade routes to India and other colonies. This event marked a significant expansion of British imperial interests in Egypt and the broader region, setting the stage for increased colonial ambitions throughout Africa and Asia in the following decades.

The Suez Canal crisis of 1956, a pivotal moment in post-colonial politics, spurred artists to respond to themes of imperialism, national identity, and the complexities of modernity. Enlightenment ideas, emphasizing reason, individual rights, and the critique of authority, found expression in various art forms, including literature, theater, and visual arts. Artists used their work to challenge colonial narratives, provoke thought on power dynamics, and explore the human condition amid geopolitical upheaval, reflecting the Enlightenment's legacy of questioning established norms. This intersection of politics and artistic expression underscored the enduring influence of Enlightenment thought on contemporary cultural movements.

Things are typically mixed and moved along a canal using a combination of boats and barges, which transport goods and materials. Canals often feature locks to manage water levels and facilitate the movement of vessels. Cargo may be loaded and unloaded at docks along the canal, where cranes or other machinery assist in transferring items. Additionally, the natural flow of water can help in the transportation process, though the movement is primarily reliant on human-operated vessels.

Haversian canals are found within the dense, compact bone tissue. They are part of the osteon, which is the structural unit of bone, and run parallel to the long axis of the bone. These canals contain blood vessels and nerves, allowing for nutrient and waste exchange, and are surrounded by concentric layers of mineralized matrix called lamellae.

Irrigation canals are man-made channels designed to transport water from a source, such as a river or reservoir, to agricultural fields. They facilitate the controlled distribution of water, ensuring that crops receive adequate moisture for growth, especially in arid regions. These canals can vary in size and complexity, ranging from simple ditches to extensive systems with gates and locks to manage water flow.

Canals significantly boosted the economy by facilitating the efficient transportation of goods and raw materials, reducing shipping costs and time. They connected inland areas to coastal ports, expanding markets for agricultural and manufactured products. This increased trade volume spurred industrial growth and the development of new industries, contributing to urbanization and job creation. Overall, canals played a crucial role in enhancing connectivity and economic development during the Industrial Revolution.

Canal rays, also known as positive rays, are streams of positively charged particles, typically ions or atoms, that are emitted from the anode during gas discharge in a cathode ray tube. They are called "canal rays" because they travel through narrow channels or "canals" formed in the gas, which is ionized by the electrons emitted from the cathode. The discovery of canal rays helped in understanding the nature of atomic structure and led to the identification of different elements based on their positive ion emissions.

A dry canal refers to a waterway or canal that is designed for navigation but lacks a continuous flow of water. Instead of being filled with water, it may be used for transportation or trade during certain seasons or is intended for future use when water is available. Dry canals can also serve as infrastructure for other purposes, such as roads or pathways.

Copenhagen has approximately 125 miles (around 200 kilometers) of canals. The most famous ones include Nyhavn, Christianshavn, and the Copenhagen Harbor. These canals play a significant role in the city's transportation and tourism, offering picturesque views and boat tours.

A canal-side walkway is a pedestrian pathway that runs alongside a canal, providing access for walking, cycling, and sometimes jogging. These walkways often feature scenic views, recreational areas, and landscaping, making them popular spots for leisure activities. They can also serve as important links between neighborhoods, parks, and urban areas, promoting community engagement and transportation alternatives.

The bilge keel radius refers to the curvature of a ship's hull at the bilge, which is the area where the bottom of the hull meets the sides. A moderate bilge keel radius helps enhance stability and reduce rolling. Dead rise is the angle between the horizontal plane and the bottom of the hull, affecting how the ship interacts with waves and its overall seaworthiness. For the Panama Canal, specific dimensions and profiles are critical to ensure safe passage through its locks and channels, often requiring vessels to adhere to defined limits for both bilge keel radius and dead rise.

The Duke of Bridgwater built his canal on the River Irwell. The Bridgwater Canal, completed in 1761, was designed to transport coal from his mines in Worsley to Manchester, significantly aiding in the industrial development of the region. This canal is often considered one of the first true canals in England and played a vital role in the expansion of the canal network during the Industrial Revolution.

The construction of the Aswan Dam, completed in 1970, allowed Egypt to exert greater control over the Nile River, which in turn enhanced its economic and strategic position in the region. This increased control over water resources bolstered Egypt's bargaining power regarding the Suez Canal, a crucial maritime route. While the dam itself was primarily focused on irrigation and hydroelectric power, its geopolitical implications contributed to a stronger Egyptian stance in negotiations and conflicts involving the canal. Overall, the dam's benefits further solidified Egypt's influence over vital waterways.

Not all canals are man-made. While many canals are constructed by humans for purposes such as irrigation, transportation, or drainage, there are also natural waterways that can resemble canals, formed by geological processes or erosion. However, the term "canal" typically refers to artificial channels created to direct water for specific uses.

Gabon has an extensive network of waterways, including around 1,200 kilometers of navigable rivers and canals. The most notable canal system is the Ngounié River, which is part of the larger river network in the country. However, specific information on the exact number of canals in Gabon is scarce, as many waterways are natural rather than man-made. Overall, the country's geography is characterized by its numerous rivers rather than a defined number of canals.

Negotiations to return the Panama Canal to Panama began in earnest in 1964. These discussions culminated in the signing of the Torrijos-Carter Treaties in 1977, which set a framework for the gradual transfer of control of the canal from the United States to Panama. The transfer was completed on December 31, 1999.

The semi-circular canals are small, fluid-filled structures located in the inner ear, each measuring about 1-2 centimeters in length and only a few millimeters in diameter. There are three semi-circular canals—horizontal, anterior, and posterior—arranged perpendicularly to one another to detect rotational movements of the head. Their size allows them to effectively sense changes in balance and orientation, playing a crucial role in maintaining equilibrium.

To register a narrowboat for use on the canal, you need to apply to the Canal & River Trust (CRT) if you're in England and Wales. This involves filling out a registration form and providing details about the boat, such as its dimensions and engine type. You must also pay a registration fee and obtain a valid boat license, which includes proof of insurance and a valid boat safety certificate. Once approved, you'll receive a registration number that should be displayed on your narrowboat.

Several improvements were made on the canal, including widening and deepening the waterway to allow for larger vessels to pass through. Lock systems were also installed to manage water levels and facilitate the movement of boats up and down the canal. Additionally, towpaths were constructed alongside the canal to allow for horse-drawn boats to be pulled along the watercourse, increasing transportation efficiency.

The water flows through the Suez Canal from north to south. The canal connects the Mediterranean Sea to the Red Sea, with the northern end located at Port Said and the southern end at Suez. This north-south flow allows ships to travel between Europe and Asia without having to navigate around the southern tip of Africa.

Ferozpur, which had the headworks of all the rivers in Pakistan, was given to India, but India agreed not to interfere in the water supply. On 1st April 1948, India stopped all the water coming into Pakistan due to which crops could not be irrigated. In May 1948, a temporary treaty was signed, according to which India would resume water supply in return for a sum of money. However, the water supply was still interfered with by India in the 1950s. In 1960, the Indus Water Treaty was signed, with the help of the World Bank, according to which Indus, Chenab and Jhelum were given to Pakistan while Ravi, Bias and Sutlej, were given to India.
