Atkinson Bureau of Reclamation, Chairman Jem ,. Chastain Federal Energy Regulatory Commission Samuel M. Huston Tennessee Valley Authority Edward Lonon Corps of Engineers ~------~ PREFACE There are presently more than 80,000 dams in use across the United States. Like any engineering works, these dams require continual care and maintenance, first to ensure that they remain operational and capable of performing all intended purposes, and then to preclude endangering people and property downstream. The safety of all dams in the United States is of considerable national, state, and local concern. Given that, the principal purpose of the TADS (Training Aids for Dam Safety) program is to enhance dam safety on a national scale. Federal agencies have responsibility for the safe operation, maintenance, and regUlation of dams under their ownership or jurisdiction. The states, other public jurisdictions, and private owners have responsibility for the safety of non-Federal dams. The safety and proper custodial care of dams can be achieved only through an awareness and acceptance of owner and operator responsibility, and through the availability of competent, well-trained engineers, geologists, technicians, and operators. Such awareness and expertise are best attained and maintained through effective training in dam safety teChnology. Accordingly, an ad hoc Interagency Steering Committee was established to address ways to overcome the paucity of good dam safety training materials. The committee proposed a program of self-instructional study embodying video and printed materials and having the advantages of wide availability/marketability, low per-student cost, limited or no professional trainer involvement, and a common approach to dam safety practices. The 14 Federal agencies represented on the National Interagency Committee on Dam Safety fully endorsed the proposed TADS program and have underwritten the cost of development. They have also made available technical specialists in a variety of disciplines to help in preparing the instructional materials. The states, through the Association of State Dam Safety Officials, also resolved to support TADS development by providing technical expertise. The darn safety instruction provided by T ADS is applicable to dams of all sizes and types, and is useful to all agencies and dam owners. The guidance in dam safety practice provided by T ADS is generally applicable to all situations. However, it is recognized that the degree to which the methods and principles are adopted will rest with the individual agency, dam owner, or user. The sponsoring agencies of T ADS assume no responsibility for the manner in which these instructional materials are used or interpreted, or the results derived therefrom.

  • The Monumental Architecture of Iklaina
    The Monumental Architecture of Iklaina Michael B. Cosmopoulos1 Abstract: The excavations of the Athens Archaeological Society at Iklaina have brought to light a major LH settle- ment that is identified with *a-pu2, one of the district capitals of the Mycenaean state of Pylos. One of the most striking features of the site is its monumental architecture, which includes at least two large buildings, two paved roads, a paved piazza, and massive built stone drains. The presence of this kind of monumentality outside the traditionally defined ‘palaces’, combined with other markers of advanced socio-political complexity, opens up a number of questions regard- ing the processes of the unification of the Mycenaean state of Pylos. In the present paper I review the relevant archi- tectural and stratigraphic evidence and assess its possible implications for this issue. It is concluded that the emergence of monumental architecture at Iklaina could have been initiated either by the Palace of Nestor following a peaceful annexation of Iklaina in the early Mycenaean period, or by the local Iklaina rulers following a period of continuous growth before a forced annexation in LH IIIB. Keywords: Monumentality, state formation, Mycenaean, Pylos, Iklaina Introduction The excavations at Iklaina are conducted under the auspices of the Archaeological Society at Athens.2 Over the course of nine field seasons we have unearthed a significant part of a LH settle- ment, which can be identified with *a-pu2, one of the district capitals of the Mycenaean state of Pylos.3 The site includes three general areas: residential, industrial, and administrative (marked as R, I, and A in Fig.

  • Seismic Performance of Rock Block Structures with Observations from the October 2006 Hawaii Earthquake
    4th International Conference on Earthquake Geotechnical Engineering June 25-28, 2007 SEISMIC PERFORMANCE OF ROCK BLOCK STRUCTURES WITH OBSERVATIONS FROM THE OCTOBER 2006 HAWAII EARTHQUAKE Edmund MEDLEY 1, Dimitrios ZEKKOS 2 ABSTRACT Unreinforced masonry construction using blocks of rock is one of the oldest forms of building, in which blocks are stacked, sometimes being mortared with various cements. Ancient civilizations used locally available rocks and cements to construct rock block columns, walls and edifices for residences, temples, fortifications and infrastructure. Monuments still exist as testaments to the high quality construction by historic cultures, despite the seismic and other potentially damaging geomechanical disturbances that threaten them. Conceptual failure modes under seismic conditions of rock block structures, observed in the field or the laboratory, are presented. A brief review is presented of the damage suffered by the culturally vital Hawaiian Pu’ukoholā and Mailekini Heiaus, rock block temples damaged by the Mw 6.7 and 6.0 earthquakes that shook the island of Hawaii on October 15, 2006. Keywords: rock block structures, Hawaii earthquakes, earthquake observations, geomechanical failures INTRODUCTION Construction of unreinforced masonry is common in various earthquake-prone regions, particularly in developing countries, and rural areas of developed countries. This vulnerable type of construction is susceptible to often devastating damage, as evident from the effects of the 2001 Bhuj, India earthquake (Murty et al. 2002), where 1,200,000 masonry buildings built primarily based on local traditional construction practices, either collapsed or were severely damaged. Buildings constructed with adobe and unreinforced masonry suffered devastating damage in the Bam, Iran 2003 earthquake (Nadim et al.

The cooperation and help of the Greek Antiquities Service, especially that of the late Dr. Nicholaos Kondoleon and of Dr. Dimitrios Lazarides, former and present directors of the Service, is most appreciated. The advice and support of Dr. Stylianos Alexiou, Ephor of Crete and Director of the Archaeological Museum of Herakleion, was especially crucial from the earliest stages of the excavation. Generous financial support for the initial stages of the project has been supplied by the chief sponsoring institutions and the Canada Council (Grants S 74-0460 and 1930), as well as the SCM Corporation of New York. Other corporations (Kodak Canada, Ltd.; Keuffel and Esser of Canada; Olivetti Canada, Ltd.; Polaroid Corporation of America; Staedtler-Mars, Ltd.) provided much-needed drafting, photographic, and office equipment. Individual help and encourage- nment,especially that of Leon Pomerance (in cooperation with the American Institute of Nautical Archaeology), Mrs. Edgar Stone, Luther Replogle, and Rue Shaw, have been most appreciated.

    MYCENAE (Abstracts from the edition of the John S. Latsis Public Benefit Foundation:ALCESTIS PAPADIMITRIOU, MYCENAE. 2015) Translation: Deborah Kazazis) THE LANDSCAPE More than any other factor, location must have determined the fortunes of Mycenae: located at the northeastern termination of the ever-fertile plain of Argos, it abutted the sea on the south, was protected by the mountain ranges of Arachnaion on the east and Artemision on the west, and lay atop a low elevation which the opening of the mountains to its north. Homer (Od. 3.263) placed the kingdom of Agamemnon “in the heart of Argos” (“µυχῷ Ἄργεος ἱπποβότοιο”), and it was as if he saw it in the shadow of the steep hills of Prophetes Elias and Zara, which like horns of consecration protected it to north and south, while the two deep ravines of Kokoretsa and Havos made it impregnable. Before the Cyclopes crowned it with its emblematic walls, this isolated piece of land, which rose 278 meters above sea level and was accessible only from the west, would have been almost invisible, appearing only to those passersby who approached it. From the summit of the acropolis, there was an unobstructed view only in the direction of Argos and the southwestern part of the plain. However, if one climbed up to the natural observatory on Prophetes Elias, they had a clear view in every direction and could mark out their kingdom at sight. Man’s choice of this location was not only dictated by its location near the main land passage from Korinthia to the Argolic plain and sea.

  • The Theory Evidence Exists That Seems to Illustrate That a Relatively
    The Theory Evidence exists that seems to illustrate that a relatively advanced culture, capable of ocean navigation, who were artistically gifted, and were capable of constructing incredibly precise megalithic buildings coded with information about the cosmos once spanned the globe in ancient times. Over the next few episodes, I’ll guide you guys on a tour around the world as we visit places like Peru, Egypt, Japan, and as remote as Easter Island, to prove to you that this ​ ​ ​ ​ ​ ​ ​ ​ civilization left its telltale signature at all of these locations. We will ask the question, was this one global civilization? Or is this the result of many ancient civilizations coming into contact with each other, and sharing their resources and knowledge, far further back in time than anyone in the mainstream is willing to allow? Origins I think the origin of this Conspiracy comes from the fact that all across the globe, Ancient Civilizations built similar Pyramids, all carefully aligned to celestial points. These same cultures mummified their dead, and built with remarkably similar techniques and peculiarities. Archaeologists and Anthropologists argue that this is all the result of these being the most obvious or simple forms of construction. While this may seem like a valid argument, as soon as you start looking at what they claim to be the “simplest” methods, it falls apart. Scientists are still to this day unable to explain many of the construction methods of ancient megalithic sites. (as we saw in our Pyramids episodes) We’ll look at more examples of this, such as the Megalithic Polygonal Architecture found all across the globe, ancient maps that depict the “new world” far further back into antiquity than is accepted, as well as evidence of Pre-Columbian contact with the Americas.

  • Exploring Natural Stone and Building a National Identity
    arts Article Exploring Natural Stone and Building a National Identity: The Geological Exploration of Natural Stone Deposits in the Nordic Countries and the Development of a National-Romantic Architecture Atli Magnus Seelow Chalmers University of Technology, Department of Architecture and Civil Engineering, Sven Hultins Gata 6, Gothenburg 41296, Sweden; [email protected]; Tel.: +46-72-968-88-85 Academic Editor: Marco Sosa Received: 22 February 2017; Accepted: 2 May 2017; Published: 12 May 2017 Abstract: In the second half of the 19th century, new methods for quarrying and processing natural stone were developed. In the Nordic countries Sweden, Norway, and Finland, this technological progress went hand in hand with a systematic geological mapping and large-scale exploitation of natural stone deposits. As a result, new constructions were developed, changing the building practice in these countries. With the end of historicism, a new architecture arose that, particularly in Norway and Finland, acquired a national-romantic character. This paper examines the interaction between geological exploration, commercial development, technical inventions, and the development of national-romantic architecture. Keywords: architecture; 19th century; 20th century; Nordic countries; natural stone; national romanticism; geology 1. Introduction In the second half of the nineteenth century, the methods for quarrying and processing natural stone were developed tremendously—parallel to the industrialization of brick production and later the advent of concrete construction. A number of technical innovations, such as the invention of the band saw or the use of power machines and explosives from the 1860s and 1880s onwards respectively, facilitated the hitherto laborious quarrying of natural stone, especially of hard rock varieties (Elliott 1992, pp.
