title: Uncertainty in experimental techniques for measuring sediment erodability.
abstract: There are many experimental methods currently utilized to measure sediment erodability and stability. When utilizing any of the available methods or devices to characterize erodability, one must understand the inherent uncertainty associated with each technique in relation to the application or expected measurement need. In addition, while some uncertainties are unique to a particular measurement device or technique, other uncertainties arise from variation in sediment conditions or properties. Several widely used devices and techniques are discussed with respect to their uncertainties and applicability for certain measurements. Finally, suggestions will be made on how to reduce uncertainty and manage it in model development.
