Fundamentals of Hydrology. Tim Davie. Water is essential to sustain life on Earth and an understanding of water quantity and quality issues is vital for anyone involved in environmental management. Fundamentals of Hydrology provides an absorbing and comprehensive introduction to how fresh water moves on and around the planet and how humans affect the quantity and quality of water available to them. It describes techniques used by practising hydrologists in the assessment of water resources. Fundamentals of Hydrology is a lively and accessible introduction to the study of hydrology and will give undergraduates an understanding of hydrological processes, a knowledge of the techniques used to assess water resources and an up to date overview of hydrology in a changing world.

The second edition of this popular book brings the text up-to-date with additional case studies and dia- grams and a greater synthesis of water quality with physical hydrology. The chapters on runoff and evaporation have been updated and the final chapter on hydrology in a changing world has more material on water resource management strategies.
Additionally the chapter on streamflow analysis now includes a more in-depth section on modelling runoff. The book begins with a comprehensive coverage of precipitation, evaporation, water stored in the ground and as snow and ice, and runoff. These physical hydrological processes show with respect to the fundamental knowledge about the process, its measurement and estimation and how it ties in with water quality. Following this is a section on analysing streamflow data, including using computer models and combining hydrology and ecology for in-stream flow assessment.
A chapter on water quality shows how to measure and estimate it in a variable environment and finishes with a section on pollution treatment.
The final chapter brings the text together to discuss water resource management and real-life issues that are faced by hydrologists in a constantly changing world. Fundamentals of Hydrology is a lively and accessible introduction to the study of hydrology at university level. This new edition continues to provide an understanding of hydrological processes, knowledge of the techniques used to assess water resources and an up-to-date overview of water resource management in a changing world.
Throughout the text, wide-ranging examples and case studies are used to clearly explain ideas and methods. Short chapter summaries, essay questions, guides to further reading and a glossary are also included.

D38 In a the groundwater is contributing to the stream, while in b the opposite is occurring 66 4. Global warming and climate change, possible rising sea levels, deforestation, desertification, and widespread soil erosion are just some of the issues of current concern. Although it is the role of human activity in such issues that is of most concern, this activity affects the operation of the natural processes that occur within the physical environment.
Most of these processes and their effects are taught and researched within the academic discipline of physical geography. A knowledge and understanding of physical geography, and all it entails, is vitally important. It is the aim of this Fundamentals of Physical Geography Series to provide, in five volumes, the fundamental nature of the physical processes that act on or just above the surface of the earth.
The topics are treated in sufficient breadth and depth to provide the coverage expected in a Fundamentals series. Each volume leads into the topic by outlining the approach adopted.
This is important because there may be several ways of approaching individual topics. Although each volume is complete in itself, there are many explicit and implicit refer- ences to the topics covered in the other volumes. Thus, the five volumes together provide a comprehensive insight into the totality that is Physical Geography. The flexibility provided by separate volumes has been designed to meet the demand created by the variety of courses currently operating in higher education institutions.
This is also the case with many Advanced Level syllabuses. Thus students and teachers are being frustrated increasingly by the lack of suitable books and are having to recommend texts of which only a small part might be relevant to their needs.
Such texts also tend to lack the detail required. It is the aim of this series to provide individual volumes of sufficient breadth and depth to fulfil new demands. The volumes should also be of use to sixth form teachers where modular syllabuses are also becoming common. Each volume has been written by higher education teachers with a wealth of experience in all aspects of the topics they cover and a proven ability in presenting information in a lively and interesting way.
Each volume provides a comprehensive coverage of the subject matter using clear text divided into easily accessible sections and subsections. References to important previous studies and results are included but are used sparingly to avoid overloading the text. Suggestions for further reading are also provided. The main target readership is introductory level undergraduate students of physical geography or environmental science, but there will be much of interest to students from other disciplines and it is also hoped that sixth form teachers will be able to use the information that is provided in each volume.
This in itself makes water an important compound, but when you add in that the availability of water varies enormously in time and space, and that water is an odd substance in terms of its physical and chemical properties, it is possible to see that water is a truly extraordinary substance worthy of study at great length.
To study hydrology is to try and understand the distribution and movement of fresh water around the globe. It is of fundamental importance to a rapidly growing world population that we understand the controls on availability of fresh water. To achieve this we need to know the fundamentals of hydrology as a science. From this position it is possible to move forward towards the management of water resources to benefit people in the many areas of the world where water availability is stressed.
There have been, and are, many excellent textbooks on hydrology. This book does not set out to eclipse all others, rather it is an attempt to fit into a niche that the author has found hard to fill in his teaching of hydrology in an undergraduate Physical Geography and Environmental Science setting. It aims to provide a solid foundation in the fundamental concepts that need to be understood by anybody taking the study of hydrology further.
These fundamental concepts are: an understanding of process; an understanding of measurement and estimation techniques; how to interpret and analyse hydrological data; and some of the major issues of change confronting hydrology. One particular aspect that the author has found difficult to find within a single text has been the integration of water quantity and quality assessment; this is attempted here. The book is aimed at first- and second-year undergraduate students.
This book also aims to provide an up-to-date view on the fundamentals of hydrology, as instrumentation and analysis tools are changing rapidly with advancing technology. As an undergraduate studying physical geography during the s, an older student once remarked to me on the wisdom of studying hydrology. There will be very little need for hydrologists soon, was his line of thought, as computers will be doing all the hydrological analysis necessary.
In the intervening twenty years there has been a huge growth in the use of computers, but fortunately his prediction has turned out to be incorrect. There is a great need for hydrologists — to interpret the mass of computer-generated information, if nothing else. Hydrology has always been a fairly numerate discipline and this has not changed, but it is important that hydrologists understand the significance of the numbers and the fundamental processes underlying their generation.
Neither of these is an adequate excuse to ignore arid regions or those dominated by snow and ice melt, and I have tried to incorporate some description of processes relevant to these environs. The book is an attempt to look at the fundamentals of hydrology irrespective of region or physical environment, but it is inevitable that some bias does creep in; I hope it is not to the detriment of the book overall.
There are many people whom I would like to thank for their input into this book. In common with many New Zealand hydrologists it was Dave Murray who sparked my initial interest in the subject and has provided many interesting discussions since.
At the University of Bristol, Malcolm Anderson introduced and guided me in the application of modelling as an investigative technique. Since then numerous colleagues and hydrological acquaintances have contributed enormously in enhancing my understanding of hydrology. I thank them all. Keith Smith initially suggested I write this text, I think that I should thank him for that! The reviewers of my very rough draft provided some extremely constructive and use- ful criticism, which I have tried to take on board in the final version.
I would particularly like to thank Dr Andrew Black from the University of Dundee who commented on the initial proposal and suggested the inclusion of the final chapter.
Thanks to Ed Oliver who drew many of the diagrams. My wife Chris, and daughters Katherine and Sarah, deserve fulsome praise for putting up with me as I worried and fretted my way past many a deadline while writing this. I am sure all scientists could, and do, point out the same thing for their discipline. The reason I was first drawn to hydrology above other scientific disciplines was to understand the processes that lead to water flowing down a river.
I wanted to know where the water flowing down a river had come from and how long it had taken to get there. I also have a social consciousness that wanted satisfaction in knowing that my learning was useful to people. As a University Lecturer from —, in addition to research, I spent a lot of time sharing my passion for hydrological understanding through teaching.
This culminated in my writing the first edition of Fundamentals of Hydrology, which was to fill a need I found in linking of water quantity and quality. Since the publication of the first edition I have been working as a scientist in a multi-disciplinary environment with a strong focus on applied research: science that directly benefits end-users. With this in mind, the second edition of Fundamentals of Hydrology has included extra sections on water resource management concepts and some of the linkages between ecology and hydrology.
This edition has also benefited from the feedback provided by readers and reviewers. In response to this feedback the text has been rewritten to a slightly higher level and there are more illustrations and case studies. The chapter structure has been simplified with the text around rainfall interception Chapter 4 in the first edition being incorporated within the precipitation and evaporation chapters.
I have also attempted to integrate the water quality and quantity aspects of hydrology to a greater degree through the addition of extra sections linking the physical processes with water quality. The second edition also provides an updated version of hydrological science. Hydrological knowledge is increasing and there is a constant need to update any text book in light of recent discoveries. In the second edition of Fundamentals of Hydrology there are over fifty new references and each chapter has been reviewed in light of recent research findings.
In addition to a changed working environment, the new edition of the book has benefited from many informal discussions on hydrological matters that I have been able to have while at work. I am grateful to my employer, Landcare Research NZ Ltd, which has generously allowed me the time to finish this second edition through the provision of Capability Funding from the New Zealand Foundation for Research Science and Technology.
In particular I think of Dave Murray who has died since the publication of the first edition. The staff at Routledge, and in particular Andrew Mould and Jennifer Page, have been extremely tolerant of my idiosyncrasies, I thank them for that. I remain particularly grateful to my wife Chris and children, Katherine and Sarah, who once again have put up with me as I work my way past deadlines but also are subjected to many impromptu hydrological lessons as we travel on holidays.
The real hudor. Modern hydrology is not evenly distributed and is not evenly accessible. It is the aim of hydrology as an applied science This wide-ranging definition suggests that all to take the knowledge of why any disparities exist water comes under the remit of a hydrologist, while and try to lessen the impact of them.
