It's a gully. Rills are smaller ditches cut by running water, but can be plowed over. Once the ditch is so deep it can't be plowed over, it's a gully.
No. There is more oxygen in deeper water.
Photosynthetic organisms need light in order to survive. In very deep water there is no light.

A deep ditch carved over time by running water is called a ravine.
A canion.
A deep gully or ditch carved by running water is called a ravine. It is typically formed by the erosive forces of flowing water over a long period of time, creating a narrow and steep-sided channel in the landscape.
This is known as a gully, which forms through erosion as water flows downhill, cutting into the soil and creating a channel. Gullies can become larger and more pronounced over time if not properly managed, leading to soil erosion and potential environmental challenges.
A deep water carved gully or ditch is a channel formed in the Earth's surface by the flow of water. These features are typically created through erosion over long periods of time, usually by rivers or streams carrying water that cuts into the land and forms a steep-walled channel. They are common in areas with high water flow or where the land is soft and easily eroded.
A canyon is a land form that is carved by running water over a long period of time, usually through erosion. The force of the water wears away the rock or soil, resulting in the formation of a deep, narrow valley with steep sides.
The word "ravine" is a noun. It refers to a deep, narrow valley with steep sides typically carved by running water.
It is called a moat
Another word for a deep ditch that is dug around a castle is a moat. You could call it a trench, or you could fill it full of water and call it a moat.
This is called a gorge and is formed over time as water erodes and cuts through the surrounding rock or soil, creating a narrow and steep-walled valley. Gorges can vary in size from small to massive, and can often be found in mountainous or canyon regions where water flow is concentrated and powerful.
A gully is a narrow and deep channel caused by erosion, often formed by running water or rainfall. It can occur in natural landscapes or as a result of human activity that disrupts the natural flow of water. Gullies can have significant impacts on the landscape and ecosystem.
The water is 27.6 in deep and slopes up to even with the running surface
