Canyon
A canion.
A deep valley carved by a river is called a canyon. Canyons are typically characterized by steep sides and are formed over long periods of time by the erosive action of flowing water.
Flooded glacial valleys are valleys carved out by glaciers during the last Ice Age which are now submerged under water. These valleys can form deep fjords, where seawater has filled in the glacially-carved depressions. Examples include the fjords of Norway and Alaska.
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.
Minnows can be carried into a dry ditch after it rains when the rainwater floods the surrounding area, allowing them to swim into the ditch. They may also be transported there by birds or other animals that can carry them in their feathers or fur from other water sources.
A deep ditch carved over time by running water is called a ravine.

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.
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.
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.
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.
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.
A deep valley carved by a river is called a canyon. Canyons are typically characterized by steep sides and are formed over long periods of time by the erosive action of flowing water.
A gully is a water-worn ravine or small valley, often caused by erosion from heavy rain or flooding. A ditch, on the other hand, is a man-made trench dug to channel water or provide drainage. While both can be used to manage water flow, gullies typically form naturally, whereas ditches are constructed by people.
The men dug a deep ditch to lay pipes for the new septic tank. I fell in the ditch, but luckily it was dry.
A ditch with deep sides is commonly referred to as a "gorge" or "ravine." These terms describe narrow, steep-sided valleys that are typically formed by the erosion of rock and soil by a river or other water flow. In some contexts, a "trench" may also be used to describe a similarly deep and narrow excavation.
