Three case studies are described in which long-term shoreline response was simulated using a numerical model. One project was along Kachemak Bay, Alaska and involved evaluation of design alternatives that included a detached breakwater, beach fill, and a revetment. The second project was on the north New Jersey coast and characterized by a long seawall and numerous groins. The third project was a model test of shoreline change behind three detached breakwaters Lake Erie. The shoreline response model used, called GENESIS, is demonstrated to have applicability to a wide range of commonly encountered shore protection situations.

The Vistula Lagoon

Three dumping sites located at the south-eastern part of the Baltic Sea (Kaliningrad Oblast) at shallow depths are considered. The first one is located to the south of the Vistula Lagoon inlet in front of a permanently eroded open marine shore segment. The second one is located to the north of the Vistula Lagoon inlet, and is used now for disposing of dredged material extracted from the Kaliningrad Seaway Canal. The third dumping site is located near the northern shore of the Sambian Peninsula to the east of the Cape Gvardeijski and assigned for disposing the dredged material extracted from the fairway to the Pionerskij Port located nearby. The last site is planned to be used for disposing of dredged material from the future port that should be constructed there before the beginning of the FIFA World Cup 2018. All three dumping sites are located not far from the eroded segments of the shore. The question behind the study is: would it possible that disposed material will naturally transported from the damping site to the shore and accumulate there to protect it from erosion? A numerical hydrodynamic-transport 3D model (MIKE) was used to model sediment transport under different wind actions. The winds with the speed stronger than 15 m/s complete wash out disposed material from the dumping site and spreading it over the wide area with a negligible layer thickness. Winds of about 7-10 m/s transport material along the shore at a distance of few kilometers that may be useful for shore protection. The first location of the dumping site (to the south of the Vistula Lagoon inlet) looks very ineffective for potential protection the shore nearby. At the other hand, the second and especially the third locations are favorable for transport of disposed material to the shore, the most favorable conditions are at onshore or alongshore currents.

The North Atlantic Oscillation

Abstract The distribution of the daily wintertime North Atlantic Oscillation (NAO) index in the 40-yr ECMWF Re-Analysis (ERA-40) is significantly negatively skewed. Dynamical and statistical analyses both suggest that this skewness reflects the presence of two distinct regimes—referred to as “Greenland blocking” and “subpolar jet.” Changes in both the relative occurrence and in the structure of the regimes are shown to contribute to the long-term NAO trend over the ERA-40 period. This is contrasted with the simulation of the NAO in 100-yr control and doubled CO2 integrations of the third climate configuration of the Met Office Unified Model (HadCM3). The model has clear deficiencies in its simulation of the NAO in the control run, so its predictions of future behavior must be treated with caution. However, the subpolar jet regime does become more dominant under anthropogenic forcing and, while this change is small it is clearly statistically significant and does represent a real change in the nature of NAO variability in the model.

We report a mass mortality of Northern Map Turtles (Graptemys geographica [LeSueur, 1817]) on the north shore of Lake Erie, Ontario, Canada. Thirty-five dead adult females were recovered from a nesting area over a period of four weeks. Predation and boat strikes were both excluded as potential cause of death, but the actual cause could not be determined because of the poor condition of the carcasses. Other possible explanations for the mortality include poisoning, drowning, and infection with an unidentified pathogen. Mass mortality in long-lived species, such as turtles, can have long-term effects on population growth and is a cause for concern in a species at risk.

Shoreface-connected ridges (SFCR) are series of ridges and troughs obliquely oriented towards the shore in the inner-continental shelf. They exist sporadically from Long Island to Florida on the North American Atlantic Shelf with maximum expression on the Delmarva peninsula (Swift et al., 1978), including the western half of Fire Island, NY. The long-term historic shoreline record of Fire Island (e.g., Allen and LaBash, 1997) shows persistent undulations in shoreline shape at an alongshore scale similar to the alongshore scale of the ridges. These ridges and troughs are spaced approximately every 2 to 3 km in the alongshore and occupy a total length about 14 km in the cross-shore direction with an average crest to trough height of 2 m.

Abstract Open cut has traditionally been the preferred method of pipeline installation traversing watercourses. It is well understood and accepted that open cut excavation of the channel bed and banks during construction causes temporary disturbance to watercourse and aquatic habitat. Horizontal directional drilling, direct push and other subsurface installation methods can potentially avoid channel bed and bank disturbance but may have unique environmental effects such as frac-outs of drilling fluid. Although highly dependent on site conditions, open cut crossings are generally less costly than comparable subsurface installation methods. When a pipeline is installed in an open cut, the pipe is typically installed on a gravel or sand bed, laid in place, surrounded by a sand pack and surrounding soils placed back in the cut in a manner that attempts to replicate the soil lithology, horizons and native compaction of the cut. It has long been thought that this sediment and soil disturbance and backfilling has the potential create a zone of geomorphological weakness at the cut where soil and sediment become dissimilar to the surrounding channel bed and banks and can result in the acceleration of bed scour, bank erosion, widening and slope instability. In this paper we examine the longer-term effects of open cut pipeline installations on the geomorphic characteristics of watercourses. Over the course of four years of field investigation, nearly 750 pipeline watercrossings throughout Ontario were visited and assessed for geomorphic stability and depth of cover. The fluvial geomorphology of Ontario is diverse and ranging from alluvial, sinuous, unconfined, low gradient watercourses in the southwest to karst-influenced morphologies in eastern Ontario and often greater slope, confined and bedrock dominated watercourses in the north. By examining the field-based geomorphological characteristics of pipeline watercourse crossings in Ontario installed by open cut and crossing a wide range of fluvial geomorphological types we will explore and draw empirically-based conclusions on whether open cuts do in fact affect the long term geomorphological conditions of the watercourse.

Innovative structuring of the decision-making process has allowed a large metropolitan planning organization, the North Jersey Transportation Planning Authority (NJTPA), to face the challenge of cooperatively developing a long-range transportation investment agenda in a complex and diverse region. The wide range of applicable geographic scales is a problem when exploring alternative strategies in such a region, so a single, multiscaled, technically based planning analysis was designed and conducted to unify decision makers around a comprehensive set of performance goals and the estimated potential effects of all reasonable actions. The analysis, built within an accelerated 10-month time frame under federal scrutiny, relied on participation by elected officials, planners, engineers, and regional stakeholders. It produced a full regionwide identification of long-term performance needs and an exhaustive assessment and prioritization of location-specific strategies. NJTPA applied this prioritization to select strategies to update its long-range transportation plan and to develop specific immediate guidance for implementation agencies.

The 19Th Century

Abstract The channel of most of the rivers is the result of long-term human endeavour to modify their shape. This paper focuses on the flow of commodities juxtaposed with the physical water flow of the river that has served over centuries as one of the main means of goods transport. The topic is closely observed on the example of the Danube regulation in Bratislava at the end of the nineteenth century and the transformation of the river into a canal. The reasons for the individual interventions in the natural riverbed differed. The third regulation (1886 - 1896) was meant to add the missing part of the canal on the route between the North and Black Seas, which would be fully adapted for freight transport by steamer. The 19th century has introduced a new paradigm to city planning. In the belief in technical innovation, the planning process was undertaken by engineers. The paper places in confrontation the oeuvre of two engineers, Charles-Joseph Minard and Enea Grazioso Lanfranconi. While the former, a French civil engineer, brought a unique way of visualizing the flow of goods between territories based on statistical data, the latter, a Hungarian hydraulic engineer, is the author of the third regulation of the Danube in the section between Devín (Theben) and Gönyű (Gönyö). For the purpose of the paper, the original theoretical work of Enea Grazioso Lanfranconi was translated and analysed. Selected data from Lanfranconi’s work was interpreted visually.

The article is devoted to the experimental practice of new local history and museum design, the study of collective identity, the actualization of “gene memory” and the representation of the Finno-Ugric ethnic group of the North of Udmurtia, Russia. The project continues to develop a long-term partnership of an inter-regional consortium consisting of specialists in the fi eld of cultural anthropology and authentic geography, local history, music and stage art, folklore, design, architecture and modern art practices, and the local community. The article deals with the study of the principles of organizing a traditional a local history museum, its tactile and spatial reconfi guration based on immersive interaction with the visitor, his active participation, polylogue, post-empathy and total involvement (psychophysiological “linkage” with reality). It covers a wide range of topics from technological to meta-immersion, creation spaces of holistic experience, space-event, space-situations, where the viewer becomes a key subject.
