Answer;
Riparian
Explanation;
The extent of water regimes and associated riparian areas is primarily determined by topography, relief, climates, flooding and soil deposition. The riparian region also exercises substantial influence over the flows in the landscape, in particular on water, nutrients, sediments, as well as animals and plant species. The appearance and limit of a riparian region thus differ from place to place. The riparian areas exist between marine and terrestrial environments in their entirety or as ecotones (transitions zones). It can also happen as incremental zones of transition called ecoclines.
