Abstract

The aim of this study was to develop a database of landscape metrics that could be used to rank the rivers in relation to potential salmon productivity. The AA. examined the rankings in relation to existing empirical (monitoring) data describing productivity of salmon stocks. To extract the metrics for each river basin they used a digital elevation model and multispectral satellite imagery. They developed procedures to extract channel networks, floodplains, on-channel lakes and other catchment features; variables such as catchment area, channel elevation, main channel length, floodplain area, and density of hydrojunctions (nodes) were measured. They processed 1509 catchments in the North Pacific Rim including the Kamchatka Peninsula in Russia and western North America. Results and discussion
