Creator:: Gudjonsson, Sigurdur
Abstract:: A hierarchical classification system of Iceland's watersheds and rivers is presented. The classification is based on Iceland's substrate, climate, water, biota, and human cultural influences. The geological formations of Iceland are very different in character depending on their age and formation history. Three major types of formations occur: Tertiary, Plio-Pleistocene,...

Creator:: McCullough, Dale A.
Abstract:: Adequate management and scientific investigation of ecosystems depends on classification of landscape systems based on all significant bio-physical and associated cultural properties. The present classification is a hierarchical systems design that can be modeled in terms of a natural system interacting with its level-specific environment. A watershed system in this...

Abstract:: Stream management and design recommendations related to the Salmon Habitat Recovery Program in the Pacific Northwest require area specific information concerning appropriate methods of stream classification, bankfull discharge recurrence intervals, and hydraulic geometry relationships. New region specific information, based on field measurements, is presented here. The Rosgen Classification of Natural...

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Creator:: Zweygardt, Louanne R.
Abstract:: Twelve stream segments in the Silvies River drainage system were classified in the fall of 1993 and again in 1994, using a morphological classification of natural rivers (Rosgen 1994). Bankfull flow of stream channels is the key feature of this system. Measurement of bankfull is used in the calculation of...

Abstract:: The nature and extent of niparian vegetation change from 1972 to 1981 in the Willamette River Greenway in Benton and Linn Counties, Oregon was quantitatively investigated. The study was primarily by aerial imagery analysis and associated field verification. A classification of vegetation and land cover within the study area was...

Abstract:: The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...
