The boundary can usually be called the water's edge, or when one is talking about a beach, the word 'shore' is used.
The boundary between land and a body of water is called a shoreline. It is the area where land meets the water, and it can vary in appearance depending on factors such as tides, erosion, and human development. Shorelines are important for ecosystems and provide a diverse habitat for plants and animals.

A natural boundary is often times a body of water such as a river. Between the US and Mexico, part of the boundary between these two countries is the Rio Grand River. A political boundary is one created by a treaty or some type of political agreement between two countries. For example, the Dominican Republic and Haiti are on the same island. The boundary between them is a political one established when France ruled Haiti and Spain ruled the Dominican Republic.
A natural boundary that is not a body of water could be formed by physical features such as mountains, deserts, or forests. These features act as barriers and define the limits of a region or country.
The boundary between the states on each shore of a body of water less than 24 nautical miles wide is typically drawn along the median (middle) line of the waterway. This approach ensures that each state has equal access to the water body and helps avoid disputes over ownership.
