Book excerpt: Landscape Evolution of Continental-Scale River Systems: A Case Study of North America's Pre-Pleistocene Bell River Basin provides a detailed case study and complete analysis of this continental-scale North American paleo-river system. The book uses detrital zircon provenance data to link incision of the Grand Canyon to deposition of its erosional products in a giant drowned delta in the Labrador Sea, in the context of sedimentary source-to-sink processes and Plio-Pleistocene continental drainage changes. The case study describes the tectonic changes in this continental-scale paleo-river system, with global implications, and contrasts this system to other continental-scale river systems around the world. This book is a valuable reference for postgraduate students, academics and researchers in the fields of geology, fluvial geomorphology and other geosciences. Readers will be able to use this detailed case study to better understand the implications for how active tectonics of headwaters regions influence delta deposition in continental-scale river systems around the world. - Details the landscape evolution of a continental-scale paleo-river system using detrital zircon geochronology with fluvial processes - Provides a multidisciplinary case study with applications to other continental-scale river systems around the world - Compares and contrasts the Bell river to the Amazon and uses these examples as analogs to discuss other systems

Book Synopsis Tectonic and Climatic Controls on Continental River Systems by : Samuel Lukens Goldberg

Download or read book Tectonic and Climatic Controls on Continental River Systems written by Samuel Lukens Goldberg. This book was released on 2021. Available in PDF, EPUB and Kindle. Book excerpt: Erosion by rivers is the dominant driver of topographic change over much of Earth's terrestrial surface, and sets the pace of change for other landscape processes. In this thesis, I explore the complexities of landscapes evolving under fluvial processes. I address questions of how rivers respond to climate, geologic substrate, and tectonics across scales, how landscape disequilibrium results from changing tectonic and climatic forces, and implications of landscape evolution for past human settlement. In the first chapter, I use a process model of river erosion that includes sediment transport feedbacks to show that climate controls the degree to which rock type affects erosion through transport limitations, with arid regions showing a much weaker dependence on rock type than humid regions. This complexity is not captured by typical models of river erosion. In the second chapter, I study the unusual case of the Rio Casiquiare, an ongoing river capture of the Amazon River from the Rio Orinoco. I use this case study to show that large lowland rivers with slope asymmetry across drainage divides reorganize their planform geometry towards a more equilibrated state, and in doing so can create perennial interbasin connections for centuries or longer. In the third chapter, I show that large lowland Amazon rivers have been quickly responsive to cyclical Quaternary climate changes, and as a result have repeatedly incised and aggraded with successive wettings and dryings of the region. In the fourth chapter, I use remote-sensing imagery and machine-learning classification to identify spatial patterns and distributions of ancient settlements, and find that they are almost universally located at the bluff edge at the interface between uplands and floodplains; this is an example of the ways in which geologic and environmental history can influence human society. These studies advance our knowledge of landscape evolution towards a more realistic understanding of the complexities of the natural world and its constant change.

Book Synopsis Remote Sensing of Geomorphology by :

Download or read book Remote Sensing of Geomorphology written by . This book was released on 2020-05-04. Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Geomorphology, Volume 23, discusses the new range of remote-sensing techniques (lidar, structure from motion photogrammetry, advanced satellite platforms) that has led to a dramatic increase in terrain information, and as such provided new opportunities for a better understanding of surface morphology and related Earth surface processes. As several papers have been published (including paper reviews and special issues) on this topic, this book summarizes the major advances in remote sensing techniques for the analysis of Earth surface morphology and processes, also highlighting future challenges. Useful for MSc and PhD students, this book is also ideal for any scientists that want to have a single volume guideline to help them develop new ideas. In addition, technicians and private and public sectors working on remote sensing will find the information useful to their initiatives. Provides a useful guideline for MSc and PhD students, scientists, technicians, and land planners on the use of remote sensing in geomorphology Includes applications on specific case studies that highlight issues and benefits of one technique compared to others Presents future trends in remote sensing and geomorphology

Book Synopsis Geomorphic Analysis of River Systems by : Kirstie A. Fryirs

Download or read book Geomorphic Analysis of River Systems written by Kirstie A. Fryirs. This book was released on 2012-09-26. Available in PDF, EPUB and Kindle. Book excerpt: Filling a niche in the geomorphology teaching market, this introductory book is built around a 12 week course in fluvial geomorphology. ‘Reading the landscape’ entails making sense of what a riverscape looks like, how it works, how it has evolved over time, and how alterations to one part of a catchment may have secondary consequences elsewhere, over different timeframes. These place-based field analyses are framed within their topographic, climatic and environmental context. Issues and principles presented in the first part of this book provide foundational understandings that underpin the approach to reading the landscape that is presented in the second half of the book. In reading the landscape, detective-style investigations and interpretations are tied to theoretical and conceptual principles to generate catchment-specific analyses of river character, behaviour and evolution, including responses to human disturbance. This book has been constructed as an introductory text on river landscapes, providing a bridge and/or companion to quantitatively-framed or modelled approaches to landscape analysis that are addressed elsewhere. Key principles outlined in the book emphasise the importance of complexity, contingency and emergence in interpreting the character, behaviour and evolution of any given system. The target audience is second and third year undergraduate students in geomorphology, hydrology, earth science and environmental science, as well as river practitioners who use geomorphic understandings to guide scientific and/or management applications. The primary focus of Kirstie and Gary’s research and teaching entails the use of geomorphic principles as a tool with which to develop coherent scientific understandings of river systems, and the application of these understandings in management practice. Kirstie and Gary are co-developers of the River Styles® Framework and Short Course that is widely used in river management, decision-making and training.
