• Abstract:
  The goal of the project was to critically review existing literature to access currently available devices, the ; identification of areas of improvement for future designs, and the outline of a new-generation cohesive sediment ; erosion measuring device. The results of this investigation shows that several devices exist for the measurement of ; cohesive sediment erosion upon which there are great opportunities for improvement. Most significantly, the ; availability of technologies such as laser Doppler velocimeters and bed mapping systems would allow for the ; noninvasive measurement of key parameters directly in the field. The introduction of such instruments to the ; framework of existing flume devices would allow for greater accuracy in determining a relationship between bed ; shear stress and suspended sediment concentration. Direct measurement of the flow profile by the LDV would erase ; the potential for error where flows were previously estimated. Acoustic bed mapping technology has already been ; successfully utilized in the NIWA-II flume to noninvasively measure the erosion process (Aberle et al. 2004, ; Debnath et al. 2007). However, the integration of more advanced technologies, whether laser-based or acoustic, has ; the potential to improve accuracy and resolution in measurements. The development of the proposed device is ; realistic and achievable, and would enhance the understanding of cohesive sediment erosion.
