  • Local scour at isolated obstacles on river beds

    Creator:
    Huang, Cheng-Chang
    Abstract:
    Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....

  • Hydraulic influences on pool morphology : a laboratory investigation

    Creator:
    Frizenschaf, Jacqueline
    Abstract:
    A flume study was conducted to investigate the influences of changing hydraulic conditions on the bed morphology of a scoured pool. During a simulated storm runoff event, responses of the pool were tested under different conditions: clearwater flow, sediment supply at steady rates, and two different sediment mixtures of the...
