Bathymetry is a critical component of any assessment of navigation channels and the projection of sedimentation rates. Applications of bathymetric assessment include the determination of current conditions of the channel and asse.
Dredging Records. Past dredging volumes, identified by time period and channel reach, provide useful data for validating prediction methods and establishing rough relationships between deposition volumes and environmental events such as storms and fl -- Test Pits. Digging test pits and measuring sediment accumulation in them provides an estimate of the deposition rate that may be expected if sediment supply and hydrodynamics are unchanged. However, projects such as channel enlargement or realignment -- Sediment Dating. Radionuclide dating methods for measuring sedimentation rates involve the measurement of radioactive isotope activity over depth in sediment cores ( Holmes 1998 ). These methods can also be used for dating specific sediment strata. T -- Tracing Sediment -- Other Data -- Error and Uncertainty in Field Observations -- Desktop Methods -- General Desktop Approaches -- Trapping Efficiency. Lake and reservoir sedimentation studies sometimes employ simple trapping calculations to estimate loss of storage capacity from sediment accumulation. The technique does not directly apply to navigation channel deposition but can -- Bottom Area Method. The bottom area , or footprint method for predicting deposition rates is not recommended. It assumes that the sedimentation rate per unit area will be the same in a modified channel as in the existing channel, so the predicted -- Volume-of-Cut Method. In the volume-of-cut method ( Trawle and Herbich 1980 , Trawle 1981 , Van Rijn 2013 ), the volume of sediment deposited in the channel is related to the volume of sediment that was removed beyond the natural depth or the depth -- Inland Channel Methods -- Coastal Channel Methods -- Machine Learning Models -- Physical Models -- Model Scales -- Moveable-Bed River Models -- Movable-Bed Coastal Models -- Fixed-Bed Tracer Models.
