inlet
Definition
An inlet is a narrow body of water that connects to a larger body of water. Inlets are often found along coastlines and can be used for transportation, fishing, and recreation.
Inlets are formed by a variety of processes, including:
- Erosion: When waves and currents erode the coastline, they can create a narrow channel that leads to a larger body of water.
- Deposition: When rivers or streams carry sediment to the coast, they can deposit it in a narrow channel, creating an inlet.
- Human activity: Humans can also create inlets by building dams or levees that divert water into a narrow channel.
Inlets are important for many reasons. They provide a place for fish to spawn and for birds to nest. They also provide a way for people to travel between different bodies of water.
Inlets can also be a source of pollution. When runoff from land enters an inlet, it can carry with it pollutants such as pesticides, fertilizers, and heavy metals. These pollutants can harm fish and other aquatic life.
How can the word be used?
The inlet was clogged with seaweed.
Different forms of the word
Noun: An inlet is a narrow body of water that flows into a larger body of water, such as a lake or an ocean.
Verb: To inlet is to create an inlet.
Adjective: Inlet means relating to an inlet. For example, an inlet valve is a valve that controls the flow of water into an inlet.
Etymology
The word "inlet" comes from the Old English word "inlæt", which means "a place where something is let in". This is a very accurate description of the meaning of the word "inlet", as it refers to a narrow body of water that flows into a larger body of water.

What is an inlet?
AQA Science Exam Question and Answer
Question:
Explain the concept of an inlet in coastal geography, detailing its formation and role in shaping coastal landforms, and discuss the significance of inlets in terms of ecological diversity and human activities.
Answer:
An inlet is a significant feature in coastal geography, characterised by a narrow strip of water extending inland from a larger body of water, such as an ocean, sea, or lake. Inlets are formed through various geological processes, including erosion, sediment deposition, and tectonic activities.
Erosion by waves and currents can create openings or channels in coastal barriers, allowing seawater to flow into otherwise enclosed areas. Sediment deposition, on the other hand, can gradually build up sandbars or spits that restrict water movement, leading to the formation of sheltered inlets. Tectonic activities like land subsidence or rising sea levels can also contribute to inlet formation.
Inlets play a crucial role in shaping coastal landforms. They can lead to the creation of estuaries, where freshwater from rivers mixes with saltwater from the sea. These dynamic environments host diverse ecosystems, making them vital for various plant and animal species. Inlets also affect sediment transport, erosion, and coastal currents, influencing the overall coastal landscape.
Beyond ecological significance, inlets have economic and recreational importance. They often serve as natural harbours for shipping and fishing activities. Additionally, their calm waters attract tourism and recreational activities such as boating, swimming, and birdwatching.
In summary, inlets are narrow water passages that play a vital role in coastal geography. Their formation, ecological diversity, and human activities all contribute to their significance in shaping coastal landscapes and supporting both natural ecosystems and human endeavours.
