Abstract: The subtopic "Measurement Techniques for Turbulent Flows"will in most casesbe understood to refer mainly to the measurement techniques for highly turbu-lent flows.Within the framework of the general conference topic "Hydraulicsand the Environment"it will,however,also be of great interest to considerthe question of minium turbulence,for example in water reservoirs(Fig.1)in order to avoid stagnant regions and thermal stratifications.The HydraulicLaboratory in Stuttgart has over the past few years investigated numerousdrinking-water reservoirs which did no longer meet the standards demanded bythe authorities due to insufficient turbulence [1].For these tests a flow-metering method was used,which provides very detailed and reliable informa-tion on the original state and the subsequent stepwise improvement towardsturbulent flow conditions [2].
