Uncertainty Associated with the Sediment Mobility Tool
Abstract
The goal of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to quantify the uncertainty associated with the forcing and sediment movement in the Sediment Mobility Tool (SMT). The beneficial use of dredged sediment through placement in the nearshore is a common practice, but answers to key questions about whether the sediment will move and where it is likely to go, remain challenging. The SMT was developed to assist coastal engineers and planners to site nearshore placement areas. SMT is a simple web application that can rapidly produce a preliminary assessment of how often sediment placed in the nearshore will be mobilized and the direction of sediment transport. Currently, the web application can be found on the Navigation Portal (http://navigation.usace.army.mil). The sediment mobility calculations used in the web application are detailed in Evaluating Sediment Mobility for Siting Nearshore Berms technical note by McFall et al. (2016), and the depth of closure calculations are detailed in Calculating Depth of Closure Using WIS Hindcast Data technical note by Brutsch et al. (2016). This technical note addresses the aleatory and epistemic uncertainties from the forcing and sediment movement in this model.
