Measuring and understanding biogenic influences upon cohesive sediment stability in intertidal systems

摘要: The Cohesive Strength Metre (CSM) is a commonly used machine to test the surface stability of exposed intertidal sediment. After its conception by Paterson (1989) has been commercially manufactured Sediment Services and many machines are now in laboratories research institutes across world. In consultation with comprehensive review CSM was undertaken an attempt improve performance reduce manufacturing costs. Although these were unsuccessful, several flaws current operating procedure identified. These investigated rectified through creation new calibration method. New component parts for erosion chamber trailed as method deployment. components failed increase accuracy or costs CSM, while deployment found be equally accurate existing but generally considered easier use.
