Chapter 6
Best Practices
Publication: Navigation Channel Sedimentation Solutions
Abstract
Best practices for predicting channel sedimentation are expressed in this chapter in terms of models, with the emphasis on numerical models; however, these concepts can lead to best use of field data, desktop modeling, and physical modeling, as needed. Sedimentation problems are best solved through a methodical, step-by-step approach. The advent of easy-to-use numerical models has increased the temptation to begin modeling immediately without the necessary preparatory steps. The Conceptual Site Model can serve to summarize various lines of evidence and conceptualize the dominant processes relevant for sedimentation at the project site. Sedimentation model validation works best when it employs a weight of evidence approach that includes visual inspection of model results plotted with observed time series and spatial data and evaluation of model performance statistics. Deterministic future sedimentation quantitative predications must be expressed in probabilistic terms based on the joint probabilities of future conditions.
