The use of Hyperspectral Technologies to Identify Riparian Habitats in Coastal Watersheds: an Example from the Navarro River, California

摘要

The Information Center for the Environment and the John Muir Institute of the Environment, at the University of California, Davis, have been assisting state and federal agencies, as well as international governments and non-governmental organizations, with resource management decision-making through environmental information brokerage and research. These activities are located throughout the world; however, intensive studies have largely focused on the state of California and California's watersheds and coastal resources in particular. From the inception of the California Rivers Assessment (Viers et al. 1998,), our research has refined the methods in which resource inventories and monitoring are carried out by regulatory agencies. This is particularly true in the case of the federal Clean Water Act and, most importantly, the provisions from Section 303(d) that articulate the development of total maximum daily loads (TMDLs) for impaired waterbodies. These TMDLs are currently being applied to non-point source pollutants in large, rural watersheds throughout northern California (see Pacific Coast Federation of Fishermen's Associations, et al. v. Marcus, No. 95-4474 MHP, March 11,1997).
