Irrigation canals do not expand from land. They expand from water into the land.
Do you mean little miniature canals? If so, irrigation

Irrigation helped farmers to grow crops because the water in the Nile would spread through the canals and create wet land, so that the wet land would grow crops. Without the river Nile Ancient Egypt would have been a desert and wouldn't have been able to grow crops and create irrigation.
The created an irrigation system and underground canals.
Irrigation systems such as irrigation ditches, channels and canals artificially supply dry land with water.A river is a system which supplies dry land with water naturally, not artificially.
That would be "irrigation."
Rivers, creeks, dams, canals and irrigation ditches.
Irrigation is the process of supplying water to land using artificial means such as man-made canals, pipes, or sprinklers to help plants grow. It is a crucial practice in agriculture to ensure crops receive enough water for optimal growth and yield.
Irrigation canals are generally aligned along the contours of the land to optimize water flow and minimize erosion. They are often designed to follow natural topography, ensuring efficient distribution of water to crops. Additionally, canals may be aligned to connect water sources, such as rivers or lakes, with agricultural areas that require irrigation. This strategic alignment helps maximize water use efficiency and supports sustainable agricultural practices.
The main method of bringing water to dry land is to use canals or pipes for irrigation. In some cases, such as in California, a canal is used to transport the water across large, flat areas, and then it is pumped through pipes to go up and down steep hillsides.
Egypt primarily relies on surface irrigation, particularly the traditional method of basin irrigation, which uses the Nile River's annual flooding to irrigate crops. In modern times, Egypt has also adopted some forms of drip and sprinkler irrigation to improve water efficiency, especially in arid regions. The country's irrigation system is vital for agriculture, given the limited arable land and water scarcity. Overall, the management of Nile water resources is crucial for sustaining Egypt's agricultural productivity.
