1 the Influence of Groyne Fields and Other Hard Defences on the Shoreline Configuration
1 The Influence of Groyne Fields and Other Hard Defences on the Shoreline Configuration 2 of Soft Cliff Coastlines 3 4 Sally Brown1*, Max Barton1, Robert J Nicholls1 5 6 1. Faculty of Engineering and the Environment, University of Southampton, 7 University Road, Highfield, Southampton, UK. S017 1BJ. 8 9 * Sally Brown ([email protected], Telephone: +44(0)2380 594796). 10 11 Abstract: Building defences, such as groynes, on eroding soft cliff coastlines alters the 12 sediment budget, changing the shoreline configuration adjacent to defences. On the 13 down-drift side, the coastline is set-back. This is often believed to be caused by increased 14 erosion via the ‘terminal groyne effect’, resulting in rapid land loss. This paper examines 15 whether the terminal groyne effect always occurs down-drift post defence construction 16 (i.e. whether or not the retreat rate increases down-drift) through case study analysis. 17 18 Nine cases were analysed at Holderness and Christchurch Bay, England. Seven out of 19 nine sites experienced an increase in down-drift retreat rates. For the two remaining sites, 20 retreat rates remained constant after construction, probably as a sediment deficit already 21 existed prior to construction or as sediment movement was restricted further down-drift. 22 For these two sites, a set-back still evolved, leading to the erroneous perception that a 23 terminal groyne effect had developed. Additionally, seven of the nine sites developed a 24 set back up-drift of the initial groyne, leading to the defended sections of coast acting as 1 25 a hard headland, inhabiting long-shore drift. -

Crannogs — These Small Man-Made Islands
PART I — INTRODUCTION 1. INTRODUCTION Islands attract attention.They sharpen people’s perceptions and create a tension in the landscape. Islands as symbols often create wish-images in the mind, sometimes drawing on the regenerative symbolism of water. This book is not about natural islands, nor is it really about crannogs — these small man-made islands. It is about the people who have used and lived on these crannogs over time.The tradition of island-building seems to have fairly deep roots, perhaps even going back to the Mesolithic, but the traces are not unambiguous.While crannogs in most cases have been understood in utilitarian terms as defended settlements and workshops for the wealthier parts of society, or as fishing platforms, this is not the whole story.I am interested in learning more about them than this.There are many other ways to defend property than to build islands, and there are many easier ways to fish. In this book I would like to explore why island-building made sense to people at different times. I also want to consider how the use of islands affects the way people perceive themselves and their landscape, in line with much contemporary interpretative archaeology,and how people have drawn on the landscape to create and maintain long-term social institutions as well as to bring about change. The book covers a long time-period, from the Mesolithic to the present. However, the geographical scope is narrow. It focuses on the region around Lough Gara in the north-west of Ireland and is built on substantial fieldwork in this area. -

Rocky Intertidal, Mudflats and Beaches, and Eelgrass Beds
Appendix 5.4, Page 1 Appendix 5.4 Marine and Coastline Habitats Featured Species-associated Intertidal Habitats: Rocky Intertidal, Mudflats and Beaches, and Eelgrass Beds A swath of intertidal habitat occurs wherever the ocean meets the shore. At 44,000 miles, Alaska’s shoreline is more than double the shoreline for the entire Lower 48 states (ACMP 2005). This extensive shoreline creates an impressive abundance and diversity of habitats. Five physical factors predominantly control the distribution and abundance of biota in the intertidal zone: wave energy, bottom type (substrate), tidal exposure, temperature, and most important, salinity (Dethier and Schoch 2000; Ricketts and Calvin 1968). The distribution of many commercially important fishes and crustaceans with particular salinity regimes has led to the description of “salinity zones,” which can be used as a basis for mapping these resources (Bulger et al. 1993; Christensen et al. 1997). A new methodology called SCALE (Shoreline Classification and Landscape Extrapolation) has the ability to separate the roles of sediment type, salinity, wave action, and other factors controlling estuarine community distribution and abundance. This section of Alaska’s CWCS focuses on 3 main types of intertidal habitat: rocky intertidal, mudflats and beaches, and eelgrass beds. Tidal marshes, which are also intertidal habitats, are discussed in the Wetlands section, Appendix 5.3, of the CWCS. Rocky intertidal habitats can be categorized into 3 main types: (1) exposed, rocky shores composed of steeply dipping, vertical bedrock that experience high-to- moderate wave energy; (2) exposed, wave-cut platforms consisting of wave-cut or low-lying bedrock that experience high-to-moderate wave energy; and (3) sheltered, rocky shores composed of vertical rock walls, bedrock outcrops, wide rock platforms, and boulder-strewn ledges and usually found along sheltered bays or along the inside of bays and coves. -

The Concrete Battleship Was Flooded, the Guns Drained of Recoil Oil and Fired One Last Time, the Colors
The Iowan History letter Vol. 5 Number 2 Second Quarter, 2016 The Concrete Initially Fort Drum was planned as a mine control and mine casemate station. However, due to inadequate de- fenses in the area, a plan was devised to level the island, and then build a concrete structure on top of it armed with Battleship two twin 12-inch guns. This was submitted to the War Department, which decided to change the 12-inch guns to 14-inch guns mounted on twin armored turrets. The forward turret, with a traverse of 230°, was mounted on the forward portion of the top deck, which was 9 ft below the top deck; the rear turret, with a full 360° traverse, was mounted on the top deck. The guns of both turrets were capable of 15° elevation, giving them a range of 19,200 yards. Secondary armament was to be provided by two pairs of 6-inch guns mounted in armored casemates on either side of the main structure. There were two 3-inch mobile AA guns on “spider” mounts for anti-aircraft de- fense.
