Frequently the discharge is being measured at designed measuring sites, equiped with measuring flumes or weirs. In reality, the standardized solutions are often not applicable (e.g. measuring flume requires long approach section that can’t be provided at a given location, etc.). In such cases, somewhat modified solutions have to be applied, with their flow characteristics (e.g. discharge curve) determined in our testing flumes.
EXAMPLES:
– measuring site with measuring flume (determination of waste-water discharge)
– measuring site with sharp-crested thin-plate rectangular weir (determination of discharge at fresh-water intake)
