Parameter: BDENS - Bulk density

Method: 1040

Matrix: US - Unfractionated

Unit: g/cm3 Description: Determination of vertical bulk density profiles by non-intrusive gamma-

ray-attenuation measurements. The gamma-ray-densitometer moves automatically along the sediment core in 1 cm steps. The magnitude of attenuation depends on the bulk density of the exposed material and the diameter of the column. (Gerland and Villiger, 1995).

Parameter: TAU_CR_E - Critical shear stress for erosion

Method: 1041


Unit: Pa Description: The SETEG-System determines a depth oriented measurement of the

critical erosion shear stress (usually in depth intervals of 2-3 cm). The sediment core is mounted on the bottom of the pressure duct, exposing the sediment surface to the flow. The continuously adjustable discharge is increased, until entrainment of sediment particles from the surface can be observed. The corresponding wall shear stress can be determined by a hydraulic calibration function which describes the relationship between wall shear stress and discharge through pressure loss.

Parameter: ERET0.44 - Erosion rate at an excess shear stress of 0.44 Pa

Method: 1042


Unit: g/cm² s Description: Determined with the SEDCIA System that consists of a laser which

projects 30 lines onto the sediment surface. To compute the loss of sediment volume over a certain period of time, snapshots of the projected lines are taken by a CCD-camera, installed at a fixed vertical and centred position above the sediment core. Subsequent snapshots are taken at given time intervals. The sediment surface is recalculated by a bilinear interpolation between the laser lines using a special computer program. The loss of sediment volume is obtained by calculating the volume difference of subsequent snapshots. Together with the density of the eroded material the sediment erosion rates can be calculated. (Witt and Westrich, 2003).
