A man-made channel filled with water and used for boat traffic and'or irrigation is called a "canal."
It is a man-made waterway designed for ships and boats to travel through, usually constructed to connect bodies of water or provide a shortcut on trade routes. Examples include the Suez Canal and the Panama Canal.
The water-filled spaces underground are called aquifers. Aquifers are underground rock formations or sediments that hold and transmit water. They are an important source of groundwater for drinking water and irrigation.
Those are called aquifers, and they are an important source of water for both human and natural systems. Aquifers allow for the storage and movement of groundwater, providing a crucial resource for drinking water, irrigation, and ecosystems.
A rock-filled rapid is called a boulder garden. This type of rapid is characterized by numerous large boulders in the river channel, creating obstacles for paddlers. Boulder gardens can be challenging to navigate but also provide opportunities for strategic route selection.
ditches filled with water so when crops needed to be watered, it can be easily dispersed. or it can catch water unneeded when it rained
It is called an aquifer, which is an underground layer of water-bearing rock or sediment that has the ability to supply water through wells or springs. Aquifers are important sources of groundwater for drinking water and irrigation.
About of Blood's flow:A fluid flow is classified as being internal or external, depending on whether the fluid is forced to flow in a confined channel or over a surface. The flow of an unbounded fluid over a surface such as a plate, a wire, or a pipe is external flow. The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. The flow of liquids in a duct is called open-channel flow if the duct is only partially filled with the liquid and there is an free surface, e.g. the flows of water in rivers and irrigation ditches.
Filled cookes are simply what it's called. They are cookies filled with ingredients such as jelly, chocolate, etc.
In early Middle Eastern civilizations probably first built canals to supply drinking and irrigation water. Gangs of laborers (called "navvies" or "navigators") first constructed British canals to provide artificial waterways for more efficient transportation of goods and materials during the Industrial Revolution of the eighteenth century. Canals served to open up countries to the Industrial Revolution, just as the Internet is opening up the world to the Information Revolution.
