  • Coupled ADCPs can yield complete Reynolds stress tensor profiles in geophysical surface flows

    We introduce a new technique to measure profiles of each term in the Reynolds stress tensor using coupled acoustic Doppler current profilers (ADCPs). The technique is based on the variance method which is extended to the case with eight acoustic beams. Methods to analyze turbulence from a single ADCP rely on questionable assumptions on turbulence anisotropy ratios and on the requirement of ...

  • Discharge Measurements In Low Flow Conditions With ADC p t echnology – First Experiences In Nepal

    Low flows prevail during about nine months of the year in Himalayan rivers as a result of the influence of the monsoon climate. They account for a large portion of the annual water balance and accurate information about these flows is therefore critical for water resources planning, development, management and hydropower design. Issues that occur with the neighbouring country India are often ...

  • OTT ADC measurement - Germany

    Background As the open pit Cottbus Nord is making use of the water of the ponds in the protected landscape of Lakoma (a village 6 km from Cottbus) the Vattenfall Europe Mining AG (VEM) as owner of the pit was obligated to take compensation measurements. VEM entrusted the engineers of the gerstgraser Ingenieurbüro für Renaturierung (gIR) in Cottbus with the planning of the ...
