Brackish

Brackish describes water that is a mixture of saltwater and freshwater, possessing a salinity level higher than freshwater but less than seawater. This typically occurs in estuaries, lagoons, and where rivers meet the ocean. The term often denotes an unpleasant or slightly salty taste and can affect the types of flora and fauna that can thrive in the environment. The level of salinity can vary considerably depending on tides, rainfall, and river discharge, creating a dynamic ecosystem.

Brackish meaning with examples

• The estuary was a haven for various bird species, adapted to feeding in the brackish waters where the river met the sea. The fluctuating salinity provided a unique habitat, different from both the freshwater upstream and the saltwater of the open ocean. These birds relied on the brackish environment for their survival.
• The coastal marshes were filled with brackish water during high tide, which provided food sources for many organisms. This mixture of freshwater and saltwater provided a wide range of nutrients, and a fertile breeding ground for many marine species. The cycle of tides created the perfect balance for life to thrive.
• The brackish taste of the well water made it undrinkable without boiling, a frustrating situation for the settlers. The water table mixed with salt water, making it unsuitable for everyday drinking. The salinity was slightly off-putting, which was a common challenge in coastal communities.
• The researchers studied the resilience of mangroves in a brackish environment, observing how these plants thrived despite the high salt content. They were interested in the adaptability of mangroves, and to see if they can withstand the extreme conditions. They compared plants in different salinity conditions.
• The low-lying agricultural fields were often inundated with brackish water during storms, damaging crops and reducing yields. The flooding was difficult to prevent, as it often coincided with times of heavy rainfall. Farmers would employ a range of protective tactics to protect crops.
