There are a couple of terms applied to poorly drained land. The worst case would be a lake or pond, a swamp would be more shallow and have vegetation growing above it, them a marsh or a bog are less wet than the others but are saturated with water.
A low area of land between hills or mountains is called a valley. Valleys are typically formed by erosion or the flow of rivers over time.
Polder land requires time for the soil to settle and stabilize after the water is drained. This process helps prevent the land from sinking or flooding in the future, ensuring it is suitable for farming. Additionally, the nutrient content of the soil may need to be replenished before crops can be successfully grown on polder land.
A lowland is land that sits lower than surrounding land. Relief is used to describe the distance between lowest and highest levels of land in any area. An area with low relief is relatively flat, with very little elevation around it. A lowland area with low relief would a flat area that is lower elevation than surrounding land.
A valley is a low area of land between hills or mountains. It is often formed by erosion or the movement of glaciers or rivers over time. Valleys can be long and narrow or wide and open.
A coastal plain is an area of low land along the coast that is formed by sediment deposition from rivers and oceans. These plains are typically flat or gently sloping and can stretch for miles along the shoreline.
A bridge that crosses an area of low-lying land that is flooded and drained by tidal streams.
The Dutch call their area of land reclaimed from the sea "polders." These are low-lying lands enclosed by dikes where water is drained to create arable land. Polders are a notable feature of the Dutch landscape and have helped expand their habitable territory.
The Fens, located in eastern England, are known for their low-lying and flat landscapes. This area was historically marshland that has been drained and converted into agricultural land, creating vast expanses of flat terrain.

A low area surrounded by higher land is called a basin. The areas are usually bowl shaped and are completely surrounded.

Plain
The Fens in East Anglia is a region in the UK that is mainly flat and low-lying. It is known for its vast expanses of flat land that were historically marshes and wetlands, which have been drained for agriculture.
Valley
It's a region of alkaline marshes in the UK, mostly drained, and very flat and low-lying. The area is located to the north of Cambridge.
That land is called a polder. Polders are created by draining water from low-lying areas, typically with the help of dikes and pumps. They are common in countries with extensive low-lying areas like the Netherlands.
