Streamflow Measurement

Autor Reginald W. Herschy
en Limba Engleză Hardback – 30 iun 2008
‘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.

Descriere

This book discusses 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. It includes coverage of the Acoustic Doppler Current Profiler (ADCP) and coverage of uncertainties in accordance with the recent International Standard on uncertainties in measurement (GUM). The book also discusses the Stage-Fall-Discharge method, hydrometric data processing, and flood flows.
