Columbia River estuary inventory of physical, biological and cultural characteristics Download PDF EPUB FB2
The Columbia River Estuary is an estuary and a bay on the Oregon–Washington border and the Pacific Coast of the United States. If the Columbia River Estuary is defined by the region that experiences ocean tides, then the estuary extends up the Columbia River to Bonneville Dam and up the Willamette River to Willamette Falls (south of Portland at Oregon City, Oregon).
The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, flows northwest and then south into the US state of Washington, biological and cultural characteristics book turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean.
The river is 1, miles (2, km) long, and Mouth: Pacific Ocean, at Clatsop County, Oregon. Small () consists of ten journal papers dedicated to the physical, chemical, and biological characteristics of the Columbia River estuary and historical changes to the estuary over the past century.
In that volume, Sherwood et al. () conclude that changes in the estuary, as well as changes in the fluvial part of the system, have. T he exploration of the north bank of the Columbia River estuary from the Cascades to the Coast is one of the most dramatic and varied episodes in the entire story of the Lewis and Clark Expedition.
In fact, it deserves to be read word by word in each of the journalists' renditions. For our purposes, however, a brief overview will suffice. general readership, is presented in The Columbia River Estuary: Atlas of Physical and Biological Characteristics, about half of which consists of text and illustrations.
The other half contains color maps of the estuary interpreting the results of the work units and the ecological synthesis. CREST developed a publication, Columbia River Estuary Inventory of Physical, Biological, and Cultural Characteristics, that was used to develop the Columbia River Estuary Regional Management Plan inwhich was adopted in the local comprehensive plans in Oregon and shoreline master programs in Washington.

The Columbia River estuary is a unique and important ecological resource. EPA's National Estuary Program (NEP) was established by Congress in in Clean Water Act amendments to improve the quality of estuaries of national significance. The Columbia River estuary is File Size: 2MB.
These watershed changes alter both the input to the estuary and the fundamental estuarine processes. Our studies of the Columbia River estuary indicate that these human alterations to watersheds can affect the interaction between river flow and the tides, modifying circulation patterns important to Cited by: The Budget Committee of the Columbia River Estuary Study Taskforce (CREST), Clatsop County, State of Oregon, to discuss the budget for the fiscal year July 1, to J will take place on at PM.
The purpose is to receive the budget message and document of the district. This project was designed to evaluate the overall condition of the Columbia River estuary. For water physical/chemical parameters, 7% of the area of the Columbia River estuary was in fair/poor condition, while nutrient indicators (nitrogen, phosphorus and chlorophyll a) showed a larger percent of the area ( 46%) in the fair/poor condition.
Evaluating Cumulative Ecosystem Response to Restoration Projects in the Columbia River Estuary, v Executive Summary This report is the second annual report of a six-year project to evaluate the cumulative effects of habitat restoration projects in the Columbia River Estuary, conducted by.
About the Columbia River Estuary Conceptual Model project. The purpose of this effort is to develop an integrated conceptual model of the lower Columbia River and estuary. This model is intended to provide a technical basis for restoration planning, monitoring, and research needs identification.
is formed through the actions of physical. This paper is also a description of the physical and biological effects of human intervention in the Columbia River Basin and estuary. The Columbia River Estuary ecosystem is less altered than many of the more-studied estuaries of the Atlantic seaboard, where human influence has been by: the Columbia River benthos in the vicinity of the route followed by the Cathlamet Ferry.
The Cathlamet Ferry is a small ferry that runs between a dock on Puget Island, Washington, which is located at River Mile (RM) on the Columbia River, and Westport, Oregon.
The objectives of the study were to determine the species. Evaluating Cumulative Ecosystem Response to Restoration Projects in the Columbia River Estuary, v Preface This report is a deliverable for the study.
As such, it includes all of our work products for the study year. Future annual reports will be prepared. We illustrate the classification by applying it to the Columbia River estuary (Oregon-Washington, USA), a system that extends about river kilometers (rkm) inland from the Pacific Ocean.
More than three-quarters of this length is tidal freshwater. The Columbia River Estuary Ecosystem ClassificationFile Size: 6MB. Columbia River Basin. The Columbia River is one of the most dominant environmental features of the Pacific Northwest. Beginning high in the mountains of southeastern British Columbia, the Columbia River flows 2, kilometers (1, miles) through alpine and subalpine environments, montane forests, lava fields, semiarid grasslands, and low-elevation rainforests before entering the Pacific Ocean.
A numerical simulation of circulation in the Columbia River estuary and plume during the summer of is used to explore the mixing involved as river water is transformed into shelf water. The model is forced with realistic river ﬂow, tides, wind stress, surface heat ﬂux, and ocean boundary conditions.

Coastal waters are more affected than the open ocean by river runoff and tidal currents. Coastal waters typically have high biologic productivities.

STM 1. The goal of the tidal-fluvial estuary study is to determine the estuary's contribution to the spatial structure and life history diversity of Columbia River salmon stocks and the implications for estuary restoration. The study targets salmon use of tidal-fresh habitats in the estuary from Rkm 75 to Bonneville Dam, and addresses four primary objectives: 1.

That channel is narrow, but periodic dredging keeps it open so that ocean-going vessels can dock as far inland as Portland, miles from the river's mouth.
