Quality of Shallow Ground Water in Alluvial Aquifers of the Willamette Basin, Oregon, By Stephen R. Hinkle Prepared as part of the National Water-Quality Assessment Program. The Willamette River is Oregon's largest river, with a basin area of 29, km2 and a mean annual discharge of m3/s. Beginning in the s, the channel was greatly simplified for navigation.
The Willamette River flows north, drain square kilometers (11, square miles) of diverse landforms and ecology. To the east, High Cascades volcanoes create the basin’s headwaters, with alpine peaks ranging up to 3, meters (11, feet). To the west, weathered volcanic and sedimentary rocks of the Coast Range bound the basin. Coniferous forests predominate in both mountain. 1. Select the study area: Willamette Valley Ecoregion (4, square mile sections). 2. Identify the population and create a sampling frame from readily available regional geographic information system (GIS) data sources. 3. Stratify the population (regional land use and soils databases). 4. Collect the Stage 1 sample ( square mile sections). 5.
The kernel of this study was whether, how and to what extent applying the various remotely sensed data that were used here, would be an effective approach to classify the historical and current land use/land cover, to monitor the dynamics of land use/land cover during the last four decades, to map the development of the irrigation areas, and to. AbstractReevaluation of the reliability of reservoirs in meeting operating objectives is needed as the landscape and operational priorities change. This study examined the individual and collective.

Estate planning for farmers
Forestry, agriculture and urban uses dominate land use in the Willamette Basin. While forestry use is active from the higher elevations to the foothills of the Coast and Cascade mountain ranges, agriculture is the largest land use in low elevation valleys.
DEQ is actively involved in a study to reduce mercury pollution in the Willamette. The Willamette Basin is Oregon's largest river basin. It contains nearly 70 percent of Oregon’s population, its most highly productive agricultural land, and significant habitat for anadromous fish populations.
The Willamette River and its tributaries make it possible to support today's population and generate hydropower. Additional Physical Format: Online version: Willamette Basin land use study.
Salem: The Division, (OCoLC) Material Type: Government. The study was undertaken to plan for the proper development of water andrelated land resources of the Willamette Basin in Oregon.
Appendix B, along with Appendices A and C, provides supporting data for the functional Appendices D through L. Climate is first discussed, including the climatic significance of geographical features such as the Pacific Ocean, the Columbia Gorge, and the Coast and. Many streams in urban areas of the Willamette River basin have been damaged.
still the main land use in the basin, are in relatively good shape. the study authors estimate. Agriculture. In its Willamette Basin Report, the Oregon Water Resources Department High salinity and high arsenic concentrations are the two major natural water-quality problems in parts of the Willamette Basin.
The study was designed to address the issues listed above by meeting the following objectives: land use, and climate, and 2) develop. Oregon's Willamette River Basin, which encompasses some of the nation's richest farm and forest land, is also home to most of Oregon's citizens.
More than 2 million people live in the Willamette Basin today, and that number is expected to reach nearly 4 million by the year The USGS has collected and compiled groundwater data for the Willamette River Basin, Oregon. This research includes data for 1, field located water wells and 6 springs, hydrographs of water-level fluctuations during various time periods for wells, borehole geophysical data for 16 wells, and water-chemistry analyses from wells and 6 springs.
The Willamette Basin Review is a cooperative feasibility study with the U.S. Army Corps of Engineers. Funding for the Study has been provided by the federal government and the State of Oregon.
The Study will determine if operational changes or modifications in the allocation of stored water would better serve present and future resource needs. The Tualatin basin contains a much larger urban land cover base whereas the Yamhill basin contains more agricultural lands and contributes more water to the Willamette River.
However, in both basins, ES like water purification and sediment retention have the potential to mitigate some of the land uses and activities negatively impacting water. COVID Resources.

Land use intro. The current (?95) quality of shallow ground water (generally, land surface) in Willamette Basin alluvium is described using results from two studies. A Study-Unit Survey, or regional assessment of shallow groundwater quality in alluvium, was done from June through August During the Study-Unit Survey, data were collected from 70 domestic wells chosen using a random.
The Willamette Story This short story, told with voices and images, offers a broad overview of the where we have come from and where we might be going as citizens of the Willamette Valley. Willamette Water A comprehensive, highly integrated examination of hydrological, ecological, and socio-economic factors in the Willamette River Basin.
There are several examples of the use of alternative futuring analysis in the United States. In Oregon, researchers modeled alternative futures for the Willamette Valley under current land use. Water, Economics, and Climate Change in the Willamette Basin, Oregon 4 is nonconsumptive, i.e., it is returned to the surface-water source from which it originated.
Second, a large fraction of urban water sup-plies in the WRB come from sources outside the Basin. Thus, consumptive use from in-basin surface water sources represents only about.

The main objective of the study is to address such questions as (1) what are the land utilizations in Kuranji River Basin, (2) what are the linkages between socioeconomic conditions of people upstream with land utilization in the Kuranji River Basin and forest conditions, and (3) what are the effects of land-use changes on Kuranji River Basin.Willamette Basin Land Use and Land Cover The land use and land cover patterns that appear circa are the results of both natural and cultural influences.
Since the mid 19th century, EuroAmerican settlement of the Willamette Valley has played a major role in establishing the patterns seen in Map Population and income growth in the Reference Case scenario raise the demand for urban land in the Willamette Basin, which raises the value of developed land over agricultural and forest land.
This increases the area of developed land by 54% between andwhile decreasing agricultural and forest land areas by -8% and -1%, respectively.
