"In 1968 an analysis was made of discharge measurement records for a number of gauging stations located in Manitoba and Northwest Territories. The purpose of the analysis was to discover the relationship between discharge measurements made on the basis of single velocity observations in the cross section, and discharge measurements made using traditional techniques. The relationship appeared to be very promising and the results were documented in the report "Preliminary Investigation into Relationship between Discharge Computed Using Single Velocity in a Cross-Section and Discharge Measured Using Standard Techniques," dated September 19, 1968. At the International Hydrological Decade Symposium on Hydrometry at Koblenz, Germany in September 1970, Mr. P.W. Strilaeff covered this subject in his paper entitled "Measurement of Discharge under Ice Cover." This paper was subsequently published as Technical Bulletin No. 29 by Inland Waters Branch; Department of Energy, Mines and Resources; Ottawa, Canada. This summary report is based on a more intensive and exhaustive analysis of the relationship by W. Bilozor, and suggests procedures to be followed when applying the single-velocity method in discharge measurement work"--Summary, p. vii.

The mission of the U.S. Geological Survey (USGS) Water Resources Discipline is to provide the information and understanding needed for wise management of the Nation's water resources. Inherent in this mission is the responsibility of collecting data that accurately describe the physical, chemical, and biological attributes of water systems. These data are used for environmental and resource assessments by the USGS, other government agencies and scientific organizations, and the general public. Reliable and quality-assured data are essential to the credibility and impartiality of the water-resources appraisals carried out by the USGS.

‘Too little water or too much’? In either case streamflow measurement is crucial. Climate change could significant affect water resources and flood management. Streamflow measurement is necessary for efficient water management. This third edition deals with all the main current methods for measuring the flow in rivers and open channels, in accordance with ISO and CEN standards and to satisfy the current requirements of the International Organization for Standardization and the European Union’s Water Directive. A new chapter on the Acoustic Doppler Current Profiler (ADCP) is included; the chapter on uncertainties has been redrafted in accordance with the recent International Standard on uncertainties in measurement (GUM); the chapters on the Stage-Fall-Discharge method and Hydrometric Data Processing have also been updated; and a new section on flood flows has been added.

Hydrometry presents a thorough introduction to the science of hydrometry: the measurement of flow in open channels. Dealing with both traditional techniques and innovative new methods and instruments, in line with the latest ISO standards, this book deals with the main themes of hydrometry: the measurement of water levels and bed levels, of discharge, and of sediment transport; it considers the use of flow measuring structures, hydrological networks, and the organization of surveys. Dr Boiten has extensive experience of teaching students from many countries and backgrounds, and has distilled this experience into a clear and comprehensive account of hydrology and water resource management. Hydrometry will appeal to graduate students and to professionals engaged in hydrology and the management of water resources.

The fresh water supplies of the Earth are finite and as the world's population continues to grow humanity's thirst for this water seems unquenchable. Intense pressure is being exerted upon freshwater resources and a lack of adequate clean water is seen as one of the most serious global problems for the 21st century. Indeed it has been said that the next war will be fought over water, not oil. Human health and the health of supporting ecosystems increasingly depends upon our ability to find, control, manage and understand water. In a single volume, The Encyclopedia of Hydrology and Water Resources provides the reader with a comprehensive overview and understanding of the diverse field of hydrology. The intimate inclusion of material on water resources emphasizes the practical applications of this field, applications which are indispensable in any modern approach to the subject. This volume is a vital reference for all hydrologists, hydrogeologists and water engineers worldwide, whether they are concerned with the exploitation of new sources of water, the protection and management of existing reserves, or the science of surface water and groundwater flow. 114 eminent scientists from 17 countries worldwide have contributed to this authoritative volume. Superbly illustrated throughout, it includes almost 300 entries on a range of key topics, including arid and semi-arid zones, climates and climate change, floods and droughts, desertification, entropy, flow measurement, groundwater, hydrological cycle, hydrological models, infiltration, karst hydrology, paleohydrology, precipitation, remote sensing, river pollution prevention, rivers, lakes and seas, satellite hydrology, soil erosion, water treatment, water use, weather radar, and world water balance.
