Spatial Variability of Beach Impact from Post-Tropical Cyclone Katia (2011) on Northern Ireland’s North Coast
Get PDFIn northern Europe, beach erosion, coastal flooding and associated damages to engineering structures are linked to mid-latitude storms that form through cyclogenesis and post-tropical cyclones, when a tropical cyclone moves north from its tropical origin. The present work analyses the hydrodynamic forcing and morphological changes observed at three beaches in the north coast of Northern Ireland (Magilligan, PortrushWest's southern and northern sectors, and Whiterocks), prior to, during, and immediately after post-tropical cyclone Katia. Katia was the second major hurricane of the active 2011 Atlantic hurricane season and impacted the British Isles on the 12-13 September 2011. During the Katia event, offshore wave buoys recorded values in excess of 5 m at the peak of the storm on the 13 September, but nearshore significant wave height ranged from 1 to 3 m, reflecting relevant wave energy dissipation across an extensive and shallow continental shelf. This was especially so at Magilligan, where widespread refraction and attenuation led to reduced shore-normal energy fluxes and very minor morphological changes. Morphological changes were restricted to upper beach erosion and flattening of the foreshore. Longshore transport was evident at Portrush West, with the northern sector experiencing erosion while the southern sector accreted, inducing a short-term rotational response in this embayment. In Whiterocks, berm erosion contributed to a general beach flattening and this resulted in an overall accretion due to sediment influx from the updrift western areas. Taking into account that the post-tropical cyclone Katia produced £100 m ($157 million, 2011 USD) in damage in the United Kingdom alone, the results of the present study represent a contribution to the general database of post-tropical storm response on Northern European coastlines, informing coastal response prediction and damage mitigation.</p

Comparative experimental approach to investigate the thermal behaviour of vertical greened façades of buildings
No full textGreening the building envelope is not a new concept, however it has not been fully approved as an energy saving method for the built environment. Vertical green can provide a cooling potential on the building surface, as plants are functioning as a solar filter and prevent the adsorption of heat radiation of building materials extensively. In this study a comparative thermal analysis of vertical green attached to a façade element is presented. An experimental set up (stationary conditions) has been developed to measure the temperature gradient through a reference cavity wall, in order to quantify the contribution of vegetation to the thermal behaviour of the building envelope. The results show temperature differences between the bare wall and between the different vertical greening systems analysed, up to 1.7 °C for the direct greening system and 8.4 °C for the living wall system based on planter boxes after 8 h of heating for summer conditions, due to the different “material” layers involved. However, the insulation material of the bare wall moderates the prevailing temperature difference between the outside and inside climate chamber, resulting in no temperature difference for the interior climate chamber for summer conditions.Materials and Environmen
Can in-store displays improve category sales and brand market share in online stores? A study on the overall effectiveness and differences between display types in an online FMCG context.
Get PDFOur study investigates the overall effects of in-store displays (ISD) on category sales and brand market share in an online shopping context, and compares the differences in effectiveness between ISD types. Using data from an online grocer, we examine three online ISD types that match with traditional ones: first screen (entrance), banner (end-of-aisle) and shelf tag (in-aisle) displays. Empirical results for 10 categories confirm that online ISD may substantially increase brand market share and to a lesser extent, category sales. Our results also demonstrate that not all types are equally effective. First screen displays clearly have the strongest effect on market share: they benefit from their placement on the ‘entrance’ location, central on-screen position and direct purchase link. While they only feature 1 SKU, banner displays typically feature all SKUs of a brand, yet, are placed on border-screen positions on traveling-zone pages without a direct purchase link. Based on our results, the advantage of banner displays does not weigh up against the advantages of first screen displays in most cases. Shelf tags, finally, may be very useful in attracting attention to interesting promotions, but appear to have no or at most a limited effect on their own.in-store displays; online grocery shopping; market response analyses;
