Download or read book Check Dams Morphological Adjustments and Erosion Control in Torrential Streams written by Carmelo Consesa Garcia and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Check dams are a potentially effective instrument for planning of hydrological risks and soil conservation. Cross structure sequences have been used in numerous areas in the world to control flooding, recharge aquifers and stabilise mountain streams, gullies and high-gradient ephemeral channels. Nevertheless, it is little known of the effectiveness of check dams and their morphological effects. This book is an attempt to compile different based-field and laboratory research works in torrential head water areas. Bed stability variations will be investigated according to check dams types, bedrock control, bed slope, channel roughness, lateral sediment input, and highly variable sediment transport capacity. Though the main purpose of check dams is to stabilise the channel bed and diminish the boundary sheer stress reaching a minor longitudinal slope, they can reduce the volume of channel-stored material favouring local scour processes downstream and occasionally destabilise the hill slopes upstream.

Download or read book Rivers in the Landscape written by Ellen Wohl and published by John Wiley & Sons. This book was released on 2020-02-10 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea level do not lie within a drainage basin. Even points distant from the nearest channel are likely to be influenced by that channel. Tectonic uplift raises rock thousands of meters above sea level. Precipitation falling on the uplifted terrain concentrates into channels that carry sediment downward to the oceans and influence the steepness of adjacent hill slopes by governing the rate at which the landscape incises. Rivers migrate laterally across lowlands, creating a complex topography of terraces, floodplain wetlands and channels. Subtle differences in elevation, grain size, and soil moisture across this topography control the movement of ground water and the distribution of plants and animals. Rivers in the Landscape, Second Edition, emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form. The book is suitable for use as a course text or a general reference on rivers. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, Rivers in the Landscape is designed to: emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; provide a concise summary of the current state of knowledge for physical process and form in rivers; reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references.

Download or read book Nature Based Solutions for Flood Mitigation written by Carla S. S. Ferreira and published by Springer Nature. This book was released on 2022-05-30 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the typical nature-based solutions (NBS) used for flood mitigation at different scales and in different areas (e.g. from catchment to hillslope scale; from urban to coastal areas). NBS can provide several ecosystem services, such as water regulation and water quality enhancement, and as such offer relevant technical solutions to complement typical grey infrastructures to mitigate flood hazard and water quality problems. In recent years, political awareness and interest from the scientific community have led to increasing implementation of NBS worldwide. In light of this trend, this book provides valuable insights into the environmental aspects of NBS, particularly their effectiveness for flood and pollution mitigation, and discusses socio-economic aspects related to the implementation of NBS, including regulatory aspects, cost, and citizens’ perceptions of NBS. Compiling the latest research, the book furthers our understanding of the role of NBS for flood mitigation and its relation to environmental aspects, to guide scientists and stakeholders in future NBS projects. It is intended for the scientific community and stakeholders, such as spatial planners and landscape managers.

Download or read book Water Resources of Lebanon written by Amin Shaban and published by Springer Nature. This book was released on 2020-07-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water has become a challenging resource that many countries worldwide are concerned with. Thus, water is often linked with health, society development, national income and even international geo-politics. Sometimes, water resources are unavailable, but successful management involves developing approaches and projects to assure water supply. However, there are some countries with available water resources, but unsatisfactory management, and thus complain about water supply becoming a national problem. This situation is prevalent in Lebanon, a country characterized by abundant water resources whether on the surface or sub-surface. It is a paradox that there is still imbalance in water supply/demand in Lebanon, and water resources are now under stress due to chaotic use. This has been exacerbated by the oscillating climatic conditions, increased population and improper management. Therefore, people receive less than one-third of their water needs, and most water supplied is of poor quality. The current status shows a descending trend. Undoubtedly, if the water sector in Lebanon continues this way, we should anticipate unfavourable (and may be severe) consequences. Many studies have been conducted on water and related disciplines in Lebanon; however, all of them focus on specific themes and sometimes defined regions. Nevertheless, the occurred changes on the influencers (natural and man-made) have not been considered. This book is the first of its type for Lebanon, and it shows all aspects of water resources with updated measurements and findings obtained by adopting new techniques. It diagnoses in-depth the major elements of water flow/storage mechanism that have never been covered in such a comprehensive manner before. Also, this book introduces and analyses the existing challenges and proposes solutions. It represents a comprehensive investigation of the water resources in Lebanon.

Available in PDF, EPUB and Kindle. Book excerpt: The state-of-the-art in water-worked bed hydraulics can only be examined through a careful exploration of the experimental (both laboratory and field) results via theoretical development. This book is primarily focused on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows, as the most up-to-date research findings in the field are presented. It begins with two reviews on bedload transport and water-work bed experimental studies. The sediment dynamics is then analyzed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and results from field studies. It is intended as a course guide for field professionals, keeping up with modern technological developments. Therefore, as a simple prerequisite, readers should have a basic knowledge of hydraulics to an undergraduate level.
