Brackel, A.K.C. (author)Brackish waters can be found in transition zones between freshwater rivers and saltier seas. These dynamic coastal landscapes harbor multiple functions such as housing, agriculture, nature, and industry. Because of climate change, existing borders between fresh and saline water - and between land and water - are becoming contested. Extreme...doctoral thesis 2024
