  • 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 ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • Pocket Gauger

    Hydro-Logic recently received major orders for the Pocket Gauger Windows Mobile software package from the two environmental regulators covering England and Wales (EA) and Scotland (SEPA). These orders have effectively confirmed Pocket Gauger's status as the UK's de-facto industry-standard system for collecting current-meter gaugings using conventional impellor-style meters. Pocket Gauger acts as ...

  • Discharge measurement deep within a cave - Case study

    Research is currently being conducted in the Hessenhau cave, located in southern Germany. The cave is the deepest known within the Swabian Alps at 144m (472 ft) and has a stream running through it that connects it to other caves within the area. ...

  • OTT SVR 100 - Surface Velocity Radar for Measuring Open Channel Flow

    Introduction The measurement of water surface velocities to determine discharge in rivers and open channels is one of the oldest measuring methods in hydrometry, well-tried and easy operably since centuries with the aid of floaters. The determination of discharge by surface velocity measurements is also covered by various hydrometric standards and guidelines such as ISO 748 “Hydrometry ...
