Lower Columbia Estuary Partnership, Charles M. Cannon, Mary F. Ramirez, Danelle W. Heatwole, Jennifer L. Burke, Charles A. Simenstad, Jim E. O'Connor, and Keith Marcoe, 2012, Columbia River Estuary Ecosystem Classification Geomorphic Catena: U.S. Geological Survey.


Estuarine ecosystems are controlled by a variety of processes that operate at multiple spatial and temporal scales. Understanding the hierarchical nature of these processes will aid in prioritization of restoration efforts. This hierarchical Columbia River Estuary Ecosystem Classification (henceforth "Classification") of the Columbia River estuary is a spatial database of the tidally-influenced reaches of the lower Columbia River, the tidally affected parts of its tributaries, and the landforms that make up their floodplains for the 230 kilometers between the Pacific Ocean and Bonneville Dam. This work is a collaborative effort between University of Washington School of Aquatic and Fishery Sciences (henceforth "UW"), U.S. Geological [...]
