The importance of investigating karstified aquifers lies in their significance as a major source of drinking water. This book describes methods that are basic to all hydrogeological studies, such as hydraulic investigations, hydrochemistry, geophysics, isotope chemistry and modelling, but with the emphasis placed on their application to karst systems. Other techniques are specific to the karst environment, such as the speleological exploration of aquifers and water tracing. The various chapters of this book are written by experts in different methods. Most of the chapters are multi-authored, and the authors include hydrogeologists who are experienced in evaluating a variety of karst environments and who together, provide a comprehensive review of karst methods.

A fascinating history of the Maya - drawing on a wealth of recent archaeological discoveries - whose civilisation in the jungles of Central America was for almost a thousand years hidden from the world.Over the last two centuries explorers have made the most remarkable discoveries in the tropical forests of Central America. Across much of present-day Mexico, Guatemala, Belize and Honduras dozens of cities - some with populations of well over 100,000 - have been unveiled, and every year fresh reports emerge of the findings of unknown Maya ruins - great temples, palaces, towering stone pyramids and the tombs of the Maya kings.What these spectacular discoveries indicate is the former presence of an exceptionally advanced, sophisticated and complex society. Recently, major developments made in the decipherment of Maya hieroglyphics have revealed that alongside the material achievements of the Maya ran intellectual accomplishments in astronomy, maths and calendrics, seemingly tied to the complexities of Maya religion, that were remarkable for a society technically in the Stone Age. From reliefs on temple walls, from magnificent hieroglyphic stairways and from stone stelae planted by Maya rulers in the plazas of their cities has come written history: the Chronicles of the Maya Kings.David Drew looks at why they constructed their cities in the hostile setting of the jungle, the exact age of their ruins, the strange human images depicted in elaborate costume at so many Maya sites, and he asks why at the time of the Spanish conquest, all knowledge of the Mayas had been lost.

First published in 1983, Man-Environment Processes provides an overview of human-environment relationships as they existed at that time, while also placing them in historical context. The book explores humanity’s impact on the natural environment by analyzing individual components—soils, plants and animals, the atmosphere, water, landforms, and oceans—as well as the cumulative effects of rural-agricultural and urban-industrial activities. Its distinctive contribution lies in integrating aspects of the natural environment that are typically studied in isolation, offering a holistic perspective that enhances understanding of complex environmental interactions.This book will be of interest to students and researchers of geography and environmental studies.

One quarter of the world's population lives in karst terrains, yet karsts are highly vulnerable to stresses caused by human activity. This book surveys human impact on karst water, showing that the increasing pollution of the environment has, to a great extent, spoiled sensitive karst ecosystems. This text examines such consequences and offers proposals for future solutions and strategies. Part One provides an overview of the functioning of karsts and of human interaction with karst environments over several millennia. Part Two consists of a systematic examination of the major areas of human activity affecting karst waters, such as agriculture, industry, mining and water exploitation. Finally, Part Three views the effects on karst groundwater within a broader societal and legislative perspective and considers possible changes of methodology and approach.

This book is a manifesto for change that showcases new policy ideas for an incoming Labour government.Organised by the Society of Labour Lawyers, the Labour Party’s legal think tank, the contributors inspire debate about Britain’s future, exploring a wide range of issues from access to justice to family law reform, housing, employment, EU and trade law, asylum and refugee law, immigration and citizenship, international law and constitutional reform.This book is a must-have collection of new insights into how a Labour government can renew Britain.
