Opis

Water remains a major issue as we enter the third millennium where more than one quarter of the world do not have safe drinking water. Consequently there is an increasing demand on hydrometry to provide the essential hydrometric information in order that the world's water resources can be managed more efficiently. This text deals with methods of measuring the flow in rivers and open channels to obtain the necessary data to serve, among others, the following functions: the supply of water systems; the control of pollution; the design of highway bridges and culverts; the management of floods; the production of power; the design and maintenance of navigation facilities; the development of recreation facilities.

Hydrometry is concerned with the measurements of all the variables in the hydrological (water) cycle and hydrological information is therefore necessary for the practice of efficient water management. Water will be a major issue as the world enters the third millennium where more than one quarter of its population still do not have safe drinking water. An increasing demand is therefore placed on hydrometry to provide the essential hydrometric information in order that the world′s water resources may be managed more efficiently. The aim of this second edition is to continue the success of the first edition by including new chapters on weather radar, remote sensing, groundwater and tree ring analysis, important in extending hydrometric records. Chapters of the first edition have been brought up to date as necessary in accordance with new technology and care has been taken to bridge the gap between past methods in hydrometry. The book therefore provides an invaluable guide to managers as well as field personnel who have operation and decision making roles in water management. Contents: Flow measurement; Instrumentation; Long river records; Precipitation measuring radar; Satellite remote sensing; Groundwater; Tree ring analysis; Transmission of hydrometric data by satellite; Maximizing the utility of river flow data; Hydrometric data processing; Uncertainties and Measuring up to water resources assessment.
