Available in PDF, EPUB and Kindle. Book excerpt: Some of the physical changes of the Oregon coast (from the California boundary to the Columbia River) which have occurred since settlement are discussed. Included are changes of the beaches and the immediate backshore, of the active dunes near the shore, and of the estuaries. Some discussion is of a more general nature, to place the specific studies in the proper perspective. The time span, arbitrarily chosen, is the period since white settlement, a little more than a century. This is the time for which historical records are available to document the nature of the changes. The purpose is to describe, measure, and explain some of the Oregon coast changes within the limitations of time and resources available. Special emphasis is placed on the beaches, dunes, and tidal marshes in the estuaries, where changes have occurred and are occurring. Many aspects of these three categories and many lines of investigation had to be left unstudied. (Author).

Download or read book Prehistory of the Oregon Coast written by R Lee Lyman and published by Routledge. This book was released on 2016-09-16 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first synthesis of the prehistory of the coast of Oregon. It analyzes the artifacts and mammalian faunal remains of three representative sites on the coast. A model of the evolution of cultural adaptational strategies is presented and tested, from which it creates a model of coastal cultural development. On a methodological level, the volume examines the overriding importance and effects of various sampling techniques.

Book excerpt: Geographers is an annual collection of studies on individuals who have made major contributions to the development of geography and geographical thought. Subjects are drawn from all periods and from all parts of the world, and include famous names as well as those less well known, including explorers, independent thinkers and scholars. Each paper describes the geographer's education, life and work and discusses their influence and spread of academic ideas. Each study includes a select bibliography and a brief chronology. The work includes a general index, and a cumulative index of geographers listed in volumes published to date. Published under the auspices of the International Geographical Union.

Download or read book Shoreline Changes Due to Jetty Construction on the Oregon Coast written by J. R. Lizarraga-Arciniega and published by . This book was released on 1975 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patterns of beach erosion and accretion due to jetty construction are examined for the coast of Oregon. All jetty systems are included with the exception of those on the Columbia River, making a total of nine systems. All evidence indicates that these areas of the Oregon coast are experiencing a seasonal reversal in the sand drift, but with a zero or near zero net drift over a several years time span. Thus, shoreline changes resulting from jetty construction are not the usual examples of jetties blocking a net drift as found in southern California and elsewhere. In general, accretion of the shoreline took place adjacent to the jetties following their construction, both to the north and south. This accretion resulted mainly from the embayment formed between the jetty and the pre-jetty shoreline, the embayment becoming filled until the shoreline is straight and again in equilibrium with the waves such that there is a zero net sand drift. In some cases, as at the entrance to Yaquina Bay, the jetties are oblique to the trend of the shoreline and so produced a protected zone from the waves where accretion could occur. Sand for the accretion adjacent to the jetties was derived from beach erosion at greater distances from the jetties. The severity of the erosion depended on the total amount of sand required for the beach accretion to a new equilibrium, and the length of beach that was undergoing erosion. When only a short stretch of beach occurs to one side of the jetties, as at Bayocean Spit, then the resulting erosion was particularly severe, in that case leading to the breaching of the spit. A computer model is developed to simulate the shoreline changes that occurred following construction of the jetties on the Siuslaw River mouth. The model demonstrates deposition next to the jetty to fill the embayment created by the jetty, and erosion at greater distances from the jetty. The shoreline advances of the model agreed closely with the actual shoreline changes found in surveys following jetty construction.

Available in PDF, EPUB and Kindle. Book excerpt: While the coast of the Pacific Northwest becomes ever more populated and developed, its beaches and cliffs continue to be altered by ocean currents and winter storms. Coastal oceanographer Paul Komar reminds readers of the area's geological and cultural history and the ever-present problem of erosion. He issues an urgent call for changes in shoreline management and attitudes toward development. 41 figures. 20 maps. 112 photos.
