flume 4
Flume 4 is a wide flume for investigations related to flow forces, discharge coefficients, specific design details, bed protection and morphological impact of hydraulic structures.
|
The flume has a zig-zag formed overflow gate at the upstream side and a vertical lifting gate at the downstream side so that water levels can be controlled easily and accurately. A sediment sieve is constructed at the downstream side for the collection of lightweight material in morphological tests. The flume has a maximum discharge of 1000 l/s. The electrically driven measurement bridge can also be used for drag tests.
