WitrynaPredicted effects of climate change on nitrogen delivery through the stream network to tidal waters between 1995 and 2025 reflect predicted changes in both flowing and impounded streams. Nitrogen losses within the stream network are estimated as a function of average stream velocity and average discharge (Ator 2024) (Table 1).
