4. Ecohydrological research: from characterising salmon habitats to catchment science.
Since the second half of the 1990s, the much broader research focus on salmon and their habitats not only led to better understanding of the ecology of the species, but also a greater appreciation of the physical and chemical processes that linked the landscape of the Girnock’s valley (Fig 1b) to the riverscape of its channel network (cf. Hynes, 1975).
