Book Study for Flushing of Salt Lagoon and Small Boat Harbor Improvements at St  Paul Harbor  St  Paul Island  Alaska  Coastal Model Investigation

Download or read book Study for Flushing of Salt Lagoon and Small Boat Harbor Improvements at St Paul Harbor St Paul Island Alaska Coastal Model Investigation written by and published by . This book was released on 1997 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1:10-scale (undistorted) three-dimensional coastal hydraulic model was initially used to investigate the design of proposed harbor improvements at St Paul Harbor, St Paul Island, Alaska, with respect to wave and current conditions in the harbor and sediment patterns at the site. Wave-induced circulation and sediment patterns seaward of the main breakwater as a result of a submerged reef were investigated. Proposed improvements consisted of deepening the entrance channel, constructing a maneuvering area and installing a wave dissipating spending beach inside the existing harbor, and constructing a submerged reef seaward of the main breakwater. In this study, the model was reactivated to optimize flushing of Salt Lagoon and small-boat harbor improvements in St. Paul Harbor. The model reproduced approximately 2,865 m (9,400 ft) of the St Paul Island shoreline, the existing harbor, the surface area of Salt Lagoon with its connecting channels to the harbor, and sufficient offshore area in the Bering Sea to permit generation of the required test waves. An 18.3m-long (60ft-long) unidirectional, spectral wave generator, an automated data acquisition and control system, and a crushed coal tracer material were used in model operation.

This book was released on 2001 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1:10-scale (undistorted) three-dimensional coastal hydraulic model was initially used to investigate the design of proposed harbor improvements at St. Paul Harbor, St. Paul Island, Alaska, with respect to wave and current conditions in the harbor and sediment patterns at the site. Wave-induced circulation and sediment patterns seaward of the main breakwater as a result of submerged reefs were investigated. Proposed improvements consisted of deepening the entrance channel, constructing a maneuvering area and installing a wave dissipating landfill inside the existing harbor, and constructing submerged reels seaward of the main breakwater. The model was reactivated in 1997 to study, on a preliminary basis, small-boat harbor improvements and flushing of Salt Lagoon in St Paul Harbor. In this study, the model was reactivated to finalize the design of small-boat harbor improvements and flushing at St. Paul Harbor. The model reproduced approximately 2,865 m (9,400 ft) of the St Paul shoreline, the existing harbor, the surface area of Salt Lagoon with its connecting channel to the harbor, and sufficient offshore area in the Bering Sea to permit generation of the required test waves. An 18.3-m-long (60-ft-long) unidirectional, spectral wave generator and an automated data acquisition and control system were used in model operation. Conclusions from study results were as follows: (a) Preliminary experiments indicated that all improvement plans would result in wave heights of less than 0.3 m (1.0-ft) in the small-boat mooring area for short-period storm wave conditions. (b) Preliminary experiments indicated that the harbor would experience long-period (surge) conditions for all the improvement plans.

Book Monitoring of Harbor Improvements at St  Paul Harbor  St  Paul Island  Alaska

Download or read book Monitoring of Harbor Improvements at St Paul Harbor St Paul Island Alaska written by Robert R. Bottin and published by . This book was released on 1997 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, St. Paul Harbor, Alaska, was approved for inclusion in the Monitoring Completed Navigation Projects Program. The objective of the monitoring plan for St. Paul Harbor was to determine if the harbor and its structures were performing (both functionally and structurally) as predicted by model studies used in the project design. Monitoring of the harbor was conducted during the period July 1993 through June 1996. Elements of the monitoring program included prototype wave gauging, wave hindcast study, wave runup, wave overtopping, bathymetric analysis, broken armor unit surveys, and photogrammetric analysis. Wave height data obtained inside the harbor appeared to validate a previous three-dimensional model study. A videotape analysis used to obtain wave runup data along the face of the St. Paul Harbor main breakwater was successful, except during periods of low visibility. Trends in wave hindcast data obtained outside the harbor correlated reasonably well with runup data in a qualitative sense. Absolute values of the hindcast significant wave heights, however, appeared to be substantially lower than the waves experienced in the prototype based on runup values measured, overtopping observed, and local forecasts. Although the St. Paul Harbor main breakwater is currently functioning in an acceptable manner and is in good condition structurally, armor stone continues to degrade. Continued deterioration is predicted due to freeze-thaw and wet-dry cycles as well as large waves and sea ice action. Photogrammetric analysis revealed most of the breakwater extension was below its design elevation.

This book was released on 2005 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study conducted in Sept. 2002 used the sediment quality triad approach to evaluate risk posed by a diesel-contaminated site to the salt lagoon on St. Paul Island, Alaska. Sediment samples were analyzed for diesel range organics and polycyclic aromatic hydrocarbons, semipermeable membrance devices were used, and a 10-day amphipod bioassay was conducted. This is a concern for the migratory birds and young northern fur seals that utilize the lagoon.

Download or read book St Paul Harbor St Paul Island Alaska Design for Wave and Shoaling Protection written by Robert R. Bottin and published by . This book was released on 1988 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1:75-scale three-dimensional hydraulic model was used to investigate the design of a proposed breakwater extension at St. Paul Harbor, St. Paul Island, Alaska, with respect to wave and shoaling conditions. The model reproduced approximately 13,500 ft of the island shoreline and included the existing harbor (located in Village Cove) and sufficient offshore area in the Bering Sea to permit generation of the required test waves. Improvement plans consisted of extensions to the existing breakwater and the installation of breakwater spurs and a new secondary breakwater structure. A 60-ft-long unidirectional, spectral wave generator, an automated data acquisition and control system, and a crushed coal tracer material were utilized in model operation. (FR).
