This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permeability is one of the most frequently used properties of a soil in the engineering practice but is also one of the most variable. Grain size distribution and density are known to significantly influence the permeability of sandy soils. Many sandy soils contain significant amounts of gravel of varying sizes. The effect of gravel content and size on permeability of sandy soils has not been closely examined. The objective of this research was to examine what effect, if any, varying proportions and sizes of gravel has on permeability values of different types of sand. Three different types of sandy soil, designated as Soil 1, Soil 2, and Soil 3, were tested for their grain size distributions and permeability values in the loose state. Based on grain size distributions, Soil 1 is a medium to fine-grained sand, Soil 2 contains the widest range of grain sizes and is the closest to being a well-graded sand, and Soil 3 is a coarse-grained sand. Additionally, three different gravel sizes, including 1′′- 3/4′′ (25.4 mm - 19.05 mm), 3/4′′- 1/2′′ (19.05 mm - 12.7 mm), and 1/2′′- #4 (12.7 mm - 4.75 mm), were chosen for the study. Each of the three gravel sizes was mixed with each of the three sands in increments of 5%, 10%, 15%, 20%, 25%, and 30%, by weight of sand, to prepare sand-gravel mixtures. The constant head permeability test was used to measure permeability of the three sands as well as their mixtures with gravel. The samples of sand and sand-gravel mixtures were poured into the permeameter in the loose state and allowed to saturate for 24 hours before measuring permeability. Three measurements of permeability were taken for each sand sample and each mixture and average values were obtained. Using Microsoft Excel, gravel content was plotted against permeability to examine the influence of a given size and proportion of gravel on each of the three types of sand used in the study. The results of this research shows that the presence of gravel influences the permeability of sandy soils, but the nature and degree of influence depends upon the type of the sand. For some sandy soils, the presence of gravel may facilitate water flow through the soil and increase their permeability whereas for others it may obstruct flow and decrease permeability. In some cases, the presence of gravel may not have any significant effect on permeability. It appears that the grain size distribution of the base sand, in relation to the gravel, plays a more important role in influencing the permeability of sand-gravel mixtures than the amount and size of gravel.
Download or read book Hydrogeology written by Kevin M. Hiscock and published by John Wiley & Sons. This book was released on 2014-06-03 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogeology: Principles and Practice provides a comprehensive introduction to the study of hydrogeology to enable the reader to appreciate the significance of groundwater in meeting current and future water resource challenges. This new edition has been thoroughly updated to reflect advances in the field since 2004. The book presents a systematic approach to understanding groundwater. Earlier chapters explain the fundamental physical and chemical principles of hydrogeology, and later chapters feature groundwater investigation techniques in the context of catchment processes, as well as chapters on groundwater quality and contaminant hydrogeology. Unique features of the book are chapters on the applications of environmental isotopes and noble gases in the interpretation of aquifer evolution, and on regional characteristics such as topography, compaction and variable fluid density in the explanation of geological processes affecting past, present and future groundwater flow regimes. The last chapter discusses groundwater resources and environmental management, and examines the role of groundwater in integrated river basin management, including an assessment of possible adaptation responses to the impacts of climate change. Throughout the text, boxes and a set of colour plates drawn from the authors’ teaching and research experience are used to explain special topics and to illustrate international case studies ranging from transboundary aquifers and submarine groundwater discharge to the over-pressuring of groundwater in sedimentary basins. The appendices provide conversion tables and useful reference material, and include review questions and exercises, with answers, to help develop the reader’s knowledge and problem-solving skills in hydrogeology. This accessible textbook is essential reading for undergraduate and graduate students primarily in earth sciences, environmental sciences and physical geography with an interest in hydrogeology or groundwater science. The book will also find use among practitioners in hydrogeology, soil science, civil engineering and planning who are involved in environmental and resource protection issues requiring an understanding of groundwater.

Download or read book Sedimentology and Sedimentary Basins written by Mike R. Leeder and published by John Wiley & Sons. This book was released on 2011-02-21 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sedimentary record on Earth stretches back more than 4.3 billion years and is present in more abbreviated forms on companion planets of the Solar System, like Mars and Venus, and doubtless elsewhere. Reading such planetary archives correctly requires intimate knowledge of modern sedimentary processes acting within the framework provided by tectonics, climate and sea or lake level variations. The subject of sedimentology thus encompasses the origins, transport and deposition of mineral sediment on planetary surfaces. The author addresses the principles of the subject from the viewpoint of modern processes, emphasising a general science narrative approach in the main text, with quantitative background derived in enabling ‘cookie’ appendices. The book ends with an innovative chapter dealing with how sedimentology is currently informing a variety of cognate disciplines, from the timing and extent tectonic uplift to variations in palaeoclimate. Each chapter concludes with a detailed guide to key further reading leading to a large bibliography of over 2500 entries. The book is designed to reach an audience of senior undergraduate and graduate students and interested academic and industry professionals.

Download or read book Geochemical Modeling of Groundwater Vadose and Geothermal Systems written by Jochen Bundschuh and published by CRC Press. This book was released on 2011-12-23 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical modeling is an important tool in environmental studies, and in the areas of subsurface and surface hydrology, pedology, water resources management, mining geology, geothermal resources, hydrocarbon geology, and related areas dealing with the exploration and extraction of natural resources. The book fills a gap in the literature through its discussion of geochemical modeling, which simulates the chemical and physical processes affecting the distribution of chemical species in liquid, gas, and solid phases. Geochemical modeling applies to a diversity of subsurface environments, from the vadose zone close to the Earth’s surface, down to deep-seated geothermal reservoirs. This book provides the fundamental thermodynamic concepts of liquid-gas-solid phase systems. It introduces the principal types of geochemical models, such as speciation, reaction-path or forward, inverse- and reactive-transport models, together with examples of the most common codes and the best-practices for constructing geochemical models. The physical laws describing homogeneous and heterogeneous chemical reactions, their kinetics, and the transport of reactive solutes are presented. The partial differential or algebraic equations representing these laws, and the principal numerical methods that allow approximate solutions of these equations that can provide useful solutions to model different geochemical processes, are discussed in detail. Case studies applying geochemical models in different scientific areas and environmental settings, conclude the book. The book is addressed to students, teachers, other professionals, and to the institutions involved in water, geothermal and hydrocarbon resources, mining, and environmental management. The book should prove useful to undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, environmental scientists, soil scientists, hydrochemists, and others interested in water and geochemistry.
