Figure 4.8. Maps of the nearshore area showing the three inputs to the quantitative bottom classification: (A) water depth, (B) bathymetric slope, and (C) acoustic-backscatter intensity. Map D shows the predicted texture of surficial sediment in the area and the mean grain size of the 14 sediment samples represented by the graph in figure 4.7. Appendix 4 describes the processing flow for the analysis, input data, and functions used to generate this classification.
