Streamflow Measurement
About this book
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 accordanc

isÂ
theÂ
combinedÂ
resultÂ
ofÂ
allÂ
climatologicalÂ
andÂ
geographicalÂ
factors
thatÂ
operateÂ
inÂ
aÂ
drainageÂ
basin.Â
ItÂ
isÂ
theÂ
onlyÂ
phaseÂ
ofÂ
theÂ
hydrologicalÂ
cycleÂ
in
whichÂ
theÂ
waterÂ
isÂ
conďŹnedÂ
inÂ
well-deďŹnedÂ
channelsÂ
whichÂ
permitÂ
accurate
measurementsÂ
toÂ
beÂ
madeÂ
ofÂ
theÂ
quantitiesÂ
involved.Â
OtherÂ
measurementsÂ
of
theÂ
hydrologicalÂ
cycleÂ
areÂ
pointÂ
measurementsÂ
forÂ
whichÂ
theÂ
uncertainties,Â
on
anÂ
arealÂ
basis,Â
areÂ
difďŹcult,Â
ifÂ
notÂ
impossible,Â
toÂ
estimate.
GoodÂ
waterÂ
managementÂ
isÂ
foundedÂ
onÂ
reliableÂ
streamďŹowÂ
information
andÂ
theÂ
ďŹnalÂ
reliabilityÂ
ofÂ
theÂ
informationÂ
dependsÂ
onÂ
theÂ
initialÂ
ďŹeld
measurements.Â
TheÂ
hydrologistÂ
makingÂ
theseÂ
measurementsÂ
hasÂ
thereforeÂ
the
responsibilityÂ
ofÂ
ensuringÂ
rawÂ
dataÂ
ofÂ
acceptableÂ
qualityÂ
areÂ
collected.Â
The
successfulÂ
processingÂ
andÂ
publicationÂ
ofÂ
theÂ
dataÂ
dependÂ
largelyÂ
onÂ
theÂ
quality
ofÂ
theÂ
ďŹeldÂ
measurements.
ThisÂ
bookÂ
isÂ
thereforeÂ
forÂ
ďŹeldÂ
hydrologistsÂ
andÂ
forÂ
studentsÂ
ofÂ
hydrologyÂ
in
universitiesÂ
andÂ
colleges.
