This analysis was performed for two reasons: 1) the KWG needed a way to focus and synthesize the results of applied research on the condition and trends of natural resources, and the factors affecting those resources; and 2) a detailed watershed analysis was needed to supplement watershed assessments planned for...

Widespread erosion of the Yellow River loess plateau has led to serious soil and water conservation problems for north central China. In the DingXi District of Gansu
Province, with less than 400 mm annual precipitation, terraced plantations for timber, fuel, or fodder form part of a large scale afforestation project...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...

Sand dunes are used as indicators of wind
power potential and examples are presented of their application
as a prospecting technique at four study sites in
the Central Columbia River Basin. Aerial reconnaissance
is combined with interpretation of photography and topographic
maps as a basis of sand dune analysis. Sand...
For several years, the profitability of farming in the Columbia Basin has been diminishing, as consistently low grain prices have not kept pace with increases in farming costs. The costs of labor, fuel, machinery, fertilizer, pesticides, transportation, accounting, and brokerage fees have combined to cause many small grain producers to...
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...
Archival information about fish and water in the Umpqua Basin can be found in reports housed in disparate locations (e.g., offices of various State and Federal agencies and local organizations). A comprehensive bibliography of grey literature, important or uncataloged reports, and published reports is one means of recording what research...
Tributaries of the Tualatin River cascade down high gradient slopes for relatively short distances, then flow into the low gradient mainstem which meanders for much of its length. The gentle, east-facing slopes of Oregon's Coast Range provide the geomorphic and climatic template for the watershed's patterns of discharge, water quality,...
