Short answer:
When fresh water meets salt water and they mix, the result is brackish water.
(See related questions for a discussion of the variety of places where this occurs.)
The name of a place where salt water and fresh water mix is often an estuary which is a partially enclosed region usually near the mouth of a river. (See related link.)
More:
An estuary is a partially enclosed area where a fresh water source such as a river flows into a salt water body such as a sea or ocean. The area is termed an estuary if both ocean and salt water influxes substantially determine the nature of the body of water, hence it would normally be partially enclosed and retaining a significant portion of fresh water influx that is not immediately diluted into the seawater.
Estuaries are often both interesting biological systems and interesting geological formations.
Note: For the more general question of where fresh and salt water meet, see related questions.
Note: If one is interested in the halocline, which is a strong vertical gradient of salt concentration form sometimes at the interface of fresh water and salt water, then that is a different question.

Brackwater
An estuary is a coastal area where fresh water from rivers and streams mixes with salt water from the ocean. These areas are characterized by dynamic ecosystems and serve as important habitats for various species of plants and animals.
Land and water intermingle at coastlines, where the land meets the sea or ocean. Saltwater and freshwater intermingle in estuaries, where rivers meet the sea, creating a unique ecosystem with a mix of salt and fresh water.

Fresh water and salt water form layers due to differences in density. Salt water is denser than fresh water, so when they come into contact, the salt water sinks beneath the fresh water, creating distinct layers. This process is known as stratification.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
A mix of fresh and salt water is called brackish water. It usually occurs in estuaries where rivers meet the sea.
Fresh water and salt water meet at a river's mouth, where fresh water becomes salty and is known as brine. This mixing often occurs in an estuary, where the river widens.
The combination of salt water and fresh water is called brackish water.
A mix of fresh and salt water is called brackish water. This type of water is found in estuaries, where rivers meet the sea, creating a unique ecosystem that supports diverse wildlife.
The movement of water when ocean and fresh water meet is called Density currents.
Underground water is called underground water, because it is "underground" not because it is fresh or salt. You can have underground salt water reservoirs just like you can have fresh water ones.
When fresh water is added to salt water, the two types of water will initially form distinct layers due to differences in density. Over time, through a process called mixing and diffusion, the fresh water and salt water will blend together, creating a more uniform salt concentration throughout the mixture.

Ponds form where rainwater and runoff meet in a depression in the landscape.
The arthur kill is a place where the salt water (ocean) and the fresh water meet together!
