Book Description
Rivers are essential to every aspect of civilization, yet how many understand how they work? Fleming takes readers on a journey along our planet's waterways, providing a scientist's reflections on the profound interrelationships that rivers have with landscapes, ecosystems, and societies.

Book Description
Geochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc.) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.

Book Description
Essential to life, water can be found in different forms all around us. This important book explains how the Earth's supply of water moves from bodies of water, to the atmosphere, and to land in a process called the water cycle . Accessible text and detailed images help explain such processes as transpiration, evaporation, condensation, and precipitation, as well as the important roles of sunlight and gravity in the water cycle. Feature boxes highlight examples of the ways in which human activity creates shortages of clean water and interferes with the water cycle. Readers are encouraged to find ways to take action and find solutions.

Book Description
The present volume "Rare Earth Elements" A 6b deseribes in its first part the origin, mode of oeeurrenee, and behavior of Y and/or RE elements in the hydrosphere and atmos phere. Separately for marine and non-marine environments (surfaee, subsurfaee, mineral, and thermal waters), the behavior of RE (ineluding Y) in the hydrosphere eomprises espeeially the relationship between eontentleomposition and the ehemistry of water, and the processes aeting during migration, removal, and preeipitation are outlined; the influenee of biologieal material is mentioned. Behavior of RE in the atmosphere involves mainly transport, regional differenees, and temporal variations as weil as removal by preeipitation; the anthropogenie influenee is only outlined. The seeond part of this volume treats, partly in a more summary manner, the eosmo and geoehemieal eyeles and the balance of Y and/or RE elements. The relationship between geodynamie position and type of magmatism, as weil as the geoehemieal variations in the geospheres, especially mantle and erust of the earth, are deseribed in greater detail.

Book Description
Originally published in 1981, this book describes and interprets the physical nature of British rivers and is authored by leading authors from universities, the Institute of Hydrology and a water Authority. The contents include data on river regimes and catchment characteristics, information on water quality in both polluted and unpolluted rivers, a full discussion of river channels and their erosion and sediment characteristics, and a consideration of river management problems in the distinctive British context. Where possible, nationwide information is presented in map form and many of the maps presented a national picture for the first time. The book will be of interest to students and scientists in a wide range of disciplines: geography, geology, environmental science, hydrology and engineering. Those professionally engaged in environmental management and the water industry should also find it useful. In summary, all who are concerned with rivers – as agents of landscape change, sedimenting phenomena, environmental resources or flood hazards will find this book as relevant now as when it was first published.

Book Description
The Handbook of Rare Earth Elements focuses on the essential role of modern instrumental analytics in the recycling, purification and analysis of rare earth elements. Due to their numerous applications, e.g. in novel magnetic materials for computer hardware, mobile phones and displays, rare earth elements have become a strategic and valuable resource. The detailed knowledge of rare earth element contents at every step of their life cycle is of great importance. This reference work was compiled with contribution from an international team of expert authors from Academia and Industry to presend a comprehensive discussion on the state-of-the-art of rare earth element analysis for industrial and scientific purposes, recycling processes and purification of REEs from various sources. Written with Analytical Chemists, Inorganic Chemists, Spectroscopists as well as Industry Practitioners in mind, the Handbook of Rare Earth Elements is an indispensable reference for everyone working with rare earth elements.
