What is water that is partly salty and partly freash?

Water that is partly salty and partly fresh is referred to as brackish water. It typically occurs in areas where freshwater from rivers or streams meets and mixes with saltwater from oceans or seas, such as estuaries and coastal wetlands. This type of water has a salinity level higher than freshwater but lower than seawater, making it a unique habitat for various plants and animals adapted to these conditions. Brackish water is crucial for maintaining biodiversity and supporting various ecosystems.
