Available in PDF, EPUB and Kindle. Book excerpt: This critical book focuses on the geomorphological landscapes of eastern Canada and provides a companion volume to “Landscapes and Landforms of Western Canada” (2017). There are a number of unique characteristics of eastern Canada’s landscapes, notably its magnificent coastlines, the extraordinary variety and extent of wetlands, the huge Great Lakes-St. Lawrence basin, the high incidence of meteorite craters, the spectacular Niagara Falls, urban karst in Montreal and Ottawa, youthful, glaciated karst in Ontario, Newfoundland, Quebec and Nova Scotia, the ubiquitous permafrost terrain of Nunavut, Labrador and northern Quebec and the magnificent arctic fjords and glaciers. Looking at coastlines, the tidal extremes of the Bay of Fundy are world renowned; the structural complexity of the island of Newfoundland is less well known, but produces an astounding variety of coastlines in close succession; the arctic fjordlands of Baffin and Ellesmere islands and the extravagant raised beaches of Hudson Bay bear comparison with the classic fjords of Norway and the Baltic Sea raised beaches. As for wetlands, there are distinctive Arctic, Subarctic, Boreal, Eastern Temperate and Atlantic wetlands, and their extent is second only to those of Russia. In the Hudson and James Bay regions, between 75-100% of the terrestrial surface is comprised of wetlands. One of North America’s largest river basins, the Great Lakes-St. Lawrence basin, has its source in Minnesota, straddles the USA-Canada border and debouches into Quebec as the St. Lawrence River and evolves through its estuary into the Gulf of St. Lawrence, a journey of almost 5,000 km. As far as meteorite craters are concerned, 10% of the world’s total are located in eastern Canada, including some of the largest and most complex landforms. They are preserved preferentially in the ancient Shield terrain of Quebec. Finally, the three million km2 of permafrost controlled relief in eastern Canada serves as a reminder of the vulnerability of eastern Canada’s landscapes to climate change. Effects of warming are expressed through thawing of the permafrost, disruption of transportation corridors and urban construction problems, ever-present geomorphic hazards.

Available in PDF, EPUB and Kindle. Book excerpt: This is the only book to focus on the geomorphological landscapes of Canada West. It outlines the little-appreciated diversity of Canada’s landscapes, and the nature of the geomorphological landscape, which deserves wider publicity. Three of the most important geomorphological facts related to Canada are that 90% of its total area emerged from ice-sheet cover relatively recently, from a geological perspective; permafrost underlies 50% of its landmass and the country enjoys the benefits of having three oceans as its borders: the Arctic, Pacific and Atlantic oceans. Canada West is a land of extreme contrasts — from the rugged Cordillera to the wide open spaces of the Prairies; from the humid west-coast forests to the semi-desert in the interior of British Columbia and from the vast Mackenzie river system of the to small, steep, cascading streams on Vancouver Island. The thickest Canadian permafrost is found in the Yukon and extensive areas of the Cordillera are underlain by sporadic permafrost side-by-side with the never-glaciated plateaus of the Yukon. One of the curiosities of Canada West is the presence of volcanic landforms, extruded through the ice cover of the late Pleistocene and Holocene epochs, which have also left a strong imprint on the landscape. The Mackenzie and Fraser deltas provide the contrast of large river deltas, debouching respectively into the Arctic and Pacific oceans.

Download or read book Landscapes and Landforms of Scotland written by Colin K. Ballantyne and published by Springer Nature. This book was released on 2021-08-24 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an appealing and informative overview of the outstanding landforms and landscapes of Scotland. Scotland is internationally renowned for the diversity of its geology, landforms and landscapes. The rock record spans most of geological time, from the Archaean to the Palaeogene, and represents the outcome of tectonic plate movements, associated geological processes, and sea-level and climate changes. Scotland incorporates primeval gneiss landscapes, the deeply eroded roots of the Caledonian mountain chain, landscapes of extensional tectonics and rifting, and eroded remnants of volcanic complexes that were active when the North Atlantic Ocean opened during the Palaeogene. The present relief reflects uplift and deep weathering during the Cenozoic, strongly modified during successive episodes of Pleistocene glaciation. This striking geodiversity is captured in this book through 29 chapters devoted to the evolution of Scotland’s scenery and locations of outstanding geomorphological significance, including ancient palaeosurfaces, landscapes of glacial erosion and deposition, evidence of postglacial landscape modification by landslides, rivers and wind, and coastal geomorphology. Dedicated chapters focus on Ice Age Scotland and the associated landscapes, which range from alpine-type mountains and areas of selective glacial erosion to ice-moulded and drift-covered lowlands, and incorporate accounts of internationally renowned sites such as the ‘Parallel Roads’ of Glen Roy, the Cairngorm Mountains and the inselbergs of Assynt. Other chapters consider the record of postglacial rock-slope failures, such as the famous landslides of Trotternish on Skye, and the record of fluvial changes since deglaciation. The sea-level history of Scotland is addressed in terms of its raised and submerged shorelines, while several chapters discuss the contrasting coastal landscapes, which range from the spectacular sea cliffs of Shetland and Orkney to the beaches and dunes of eastern Scotland. The role of geoconservation in preserving Scotland’s outstanding geomorphological heritage is outlined in the final chapter. The book offers an up-to-date and richly illustrated reference guide for geomorphologists, other Earth scientists, geographers, conservationists, and all those interested in geology, physical geography, geomorphology, geotourism, geoheritage and environmental protection.

Download or read book Meandering Streamflows: Patterns and Processes across Landscapes and Scales written by A. Finotello and published by Geological Society of London. This book was released on 2024-10-02 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meandering patterns shaped by fluid flows are found over a broad range of landscapes, from bedrock channels to rivers and estuaries, deep-marine environments, supraglacial streams and other planets such as Mars and Venus. During the last six decades, meanders have been widely investigated by researchers from different fields, such as fluid mechanics, geomorphology, ecology, civil- and petroleum engineering, and geology. This volume seeks to push the science of meandering forward by bringing together insights gained from field, laboratory and numerical investigations of meandering streams found in distinct environmental and geological contexts. The authors pay particular attention to the interactions between autogenic and allogenic processes that affect meander kinematics and the resulting morphology, sedimentology and stratigraphic architecture. The findings presented in this volume contribute to a better understanding of stream meandering in diverse settings, with broad implications for stream and wetland restoration, land management, infrastructure design, oil exploration and production, carbon sequestration, hazard mitigation and planetary palaeoenvironmental reconstructions.
