INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

Nemeth B.S., University of Southern California, 1962 M.S., University of Southern California, 1969 May, 1977 ACKNOWLEDGMENTS In order to conduct this study of a remote and somewhat inhospi­ table area it was necessary to enlist the aid of many individuals and organizations. The author wishes to thank Dr. Harley J. Walker for proposing the expedition; offering guidance, assistance, and suggestions throughout the project; working out the logistics of the field study; sharing his vast knowledge of the arctic; and acting as co-major professor. Without his assistance this project would not have been possible. Dr. Donald R. Lowe, co-major professor, provided assistance, many valuable suggestions, and took time from his busy schedule to take on the burden of co-major professor at a late date. The author would also like to thank his minor professor, Dr. Robert A. Muller, and the other members of the doctoral committee, Dr. Donald H. Kupfer and Dr. Judith A. Schiebout, for their assistance and suggestions. Valuable suggestions were also given by Dr. Clarence 0. Durham, Jr. and Dr. James P. Morgan, who served as co-major professor until his retirem ent. The author gratefully acknowledges Dr. Prentiss E. Schilling who designed the statistical analyses and Dr. Penelope Hale who con­ ducted the analyses and offered valuable consultation along the way. M essrs. Jeffrey Peake, Lawrence McKenzie, and Donald White, and Dr. William Richie aided with the field work. Laboratory facilities and supplies were provided by the Depart­ ment of Geology, Louisiana State University. Travel expenses were financed through a Penrose Grant from the Geological Society of America. ii Logistic support in Alaska was supplied by the Naval Arctic Research Laboratory, Barrow, Alaska. The project was supported through the Office of Naval Research, under contract N00014-69-A-0211-0003, Project NR 388 02. The manuscript was diligently typed by Mrs. Mary M e v e rs. This study would not have become a reality without the support of the author’s family and especially his wife, Darlyne, who persevered throughout the project and assisted in ways too numerous to mention. iii TABLE OF CONTENTS Page TITLE PAGE.............................................................................................................................. i A ' ACKNOWLEDGMENTS........................ i i LIST OF FIGURES............................................................................................................... v i i LIST OF SYMBOLS . ...................................................................................................... x LIST OF TABLES................................................................... x i i ABSTRACT................................................................................................................................... x i i i INTRODUCTION......................................................................................................................... 1 THE STUDY AREA............................................................................. 2 Nomenclature ............................................................................................................... 2 C lim a te .............................................................................................................................. 5 H y d ro lo g y ......................................................................................................................... 6 Environmental Subareas ....................................................................................... 8 PROCEDURES. ‘............................................................................................................... 15 Samples Collected ..................................................................................................... 15 Method Employed .......................................................................................................... 16 MORPHOLOGIC CHANGES ..................................................................................................... 17 Before Spring Flooding ....................................................................................... 17 Thickness of Snow Cover ............................................................................. 17 Ablation of Snow Cover .................................................................................. 23 Thickness of River Ice .................................................................................. 24 Spring Flooding .......................................................................................................... 25 Summer Flow Regim e ................................................................................................ 39 Page SEDIMENTS.................................................... 43 Grain Size S tatistical Parameters. ....................................... 47 Change with Elevation and Location ...................................................... 47 Group I —Submerged River Sediments and a ll Nongravel Bar Sediments ................................................................................................. 48 Group II—Gravel Deposits of the Longitudinal Bar. 52 Environmental Subareas and Grain Size S tatistical P a r a m e t e r s ...................................................................................................... 55 Scatter Plots ................................................................................................ 57 D is c u s s io n ................................................................................................ 61 Group 1 ................................................................................................................ 61 Group I I ..........................................................................................................

  • PADDLING TRAIL River Thames: Putney to Old Isleworth
    PADDLING TRAIL River Thames: Putney to Old Isleworth Key Information Start: Putney Slipway, Putney Portages: 0 For more Embankment, Putney, Time: 2-4 hours information scan SW15 1JW Distance: 8 miles the QR code or Finish: Isleworth Draw Dock, OS Map: Explorer 161 https://bit.ly/2Lyh5 Church St, Old Isleworth, London South k1 TW7 6BG & 173 London North This is a busy and tidal part of the River Thames. You must visit boatingonthethames.co.uk to check tide times and safety advice before undertaking this trail. The trail covers the Upper Tideway in south west London, with sweeping aspects of the river. The course of the annual University Boat Race forms part of the trail. 1. We recommend you paddle with the assistance of the tidal flow, departing from Putney in the first 2 hours of the flood tide. Closely timing the tides can allow a return trip. Put in at the public slipway, crossing to the Football Stadium side of the river and turning left, for correct rules of travel. 2. Approaching Hammersmith Bridge the London Wetland Centre is behind the tree line on the opposite bank. Beware of the tide pushing you into Dove Pier after the b ridge. 3. Between Hammersmith and Chiswick Ait the river is flanked by elegant houses. At Chiswick Ait an option is to take the inside channel; usually passable after an hour or so of a flood tide. 4. Chiswick Pier signals a crossing point for a change in navigation rules. Keep the green marker buoys on your right on this sweeping bend of the river to Chiswick Bridge.

  • Application of Remote Sensing and GIS Technology for Monitoring Coastal Changes in Estuary Area of the Red River System, Vietnam
    Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, Vol. 31, No. 6-2, 529-538, 2013 http://dx.doi.org/10.7848/ksgpc.2013.31.6-2.529 Application of Remote Sensing and GIS technology for monitoring coastal changes in estuary area of the Red river system, Vietnam Pham Thi Lan1) · Tong Si Son2) · Kavinda Gunasekara3) · Nguyen Thi Nhan4)· La Phu Hien5) Abstract Coastline is the most dynamic part of seascape since its shape is affected by various factors. Coastal zone is an area with immense geological, geomorphological and ecological interest. Monitoring coastal change is very important for safe navigation, coastal resource management. This paper shows a result of monitoring coastal morphological changes using Remote Sensing and GIS. Study was carried out to obtain intensity of erosion, deposition and sand bar movement in the Red River Delta. Satellite images of ALOS/AVNIR-2 and Landsat were used for the monitoring of coastal morphological changes over the period of 1975 to 2009. Band rationing and threshold technique was used for the coastline extraction. Tidal levels at the time of image acquisition varied from -0.89m to 2.87m. Therefore, coastline from another image at a different tidal level in the same year was considered to get the corrected coastline by interpolation technique. A series of points were generated along the coastal line from 1975 image and were established as reference points to see the change in later periods. The changes were measured in Euclidean distances from these reference points. Positive values represented deposition to the sea and negative values are erosion.

    DOCUMENT #f, / RECORD OF DECISION USDA Forest Service Kaibab National Forest CANYON MINE PROPOSAL Final Environmental Impact Statement Coconino County, Arizona r - . t __ .. 915 RECORD OF DECISION / J USDA Forest Service Kaibab National Forest CANYON MINE PROPOSAL Final Environmental Impact Statement Coconino County, Arizona I. Introduction This Recor't:l of Decision docl.lllents my approval of a modified Plan of Operations for the Canyon Uranium ~ine on the Kaibab National Forest. The alternatives considered and my rationale for selecting the preferred alternative are described in this Record of Decision. The environmentally preferred alternative is also identified. In October, 1984, Energy Fuels Nuclear, Inc. (EFN), submitted to the USDA Forest Service, Kaibab National Forest, a proposed Plan of Operations to mine uranium on unpatented mining claims on the Tusayan Ranger District. The proposed mine is located in Coconino County, Arizona, approximately six miles south of the community of Tusayan. A detailed description of the proposed mine operations can be found in the Environmental Impact Statement (EIS). In brief, the proposed Canyon Mine would involve underground mining of a breccia pipe uranium deposit and would require disturbance of approximately 17 acres for the mine shaft and surface facilities. Ore from the rrJine ~ will be trucked to t.he licensed mill near Blanding, Utah. When the Plan of Operations was submitted, the Forest Service sought public review and COlTInent on tbe proposal to assist in determining the appropriate levei of analysis and documentation required under the ~ational Environmental Policy Act (NEPA). The Forest Service decided the preparation of an EIS was "'erranted and c notice to prepare an EIS was published in the Federal Register on April 30, 1985.

Juanda no. 193, Bandung E‐Mail: [email protected] Diterima: 30 Maret 2011; Disetujui: 10 Agustus 2011 ABSTRAK Pada sungai dengan material dasar sungai tidak seragam, ukuran butir, rapat massa dan keberadaan butir­ butir material terhadap aliran sungai akan sangat mempengaruhi gerak mula masing­masing butir material dasar sungai. Aliran sungai akan terlebih dahulu mengangkut material dasar sungai dengan ukuran butir yang relatif kecil dan tidak terlindungi, sementara butir­butir dengan ukuran yang lebih besar dan stabil akan membentuk lapisan perisai di permukaan dasar sungai. Karena angkutan sedimen terpilah, pembentukan lapisan perisai dan pembentukan corak dasar sungai sangat terkait erat dengan laju angkutan sedimen, maka kecermatan penyimulasian fenomena­fenomena tersebut akan sangat mempengaruhi ketelitian analisis kedalaman aliran, laju muatan sedimen dasar, laju angkutan sedimen layang dan pada akhirnya juga akan mempengaruhi kecermatan analisis perubahan morfologi sungai. Dalam tulisan bagian pertama ini dibahas dengan detail studi pustaka dan landasan teori untuk pengembangan model numerik angkutan material sedimen terpilah, prediksi ketebalan lapisan aktif, mekanisme pertukaran antara material dasar sungai, angkutan sedimen dasar dan angkutan sedimen layang, pembentukan corak dasar sungai dan pembentukan lapisan perisai pada sungai dengan material dasar sungai tidak seragam.
