Methods used to determine PN burial rates varied but all included an estimate of sediment accumulation rate ( Pb, sediment budget, pollen grain analysis) and an estimate of PN concentration at a depth in the sediment column where concentrations were constant with further depth.

The further development of mathematical representations of estuarine processes should proceed simultaneously with investigations of both specific sedimentary processes and regional sedimentary systems. For the model proposed here some of the specific processes that deserve attention in the future include the processes that control the rate of formation of marine mud at the base of the surficial layer of agglomerates and the relationship between the eddy-diffusion coefficient for sand transport and fluctuations in the water velocity. The study of specific processes tell us little about the long-term manifestations of these processes. For this there is the need to develop comprehensive descriptions of estuarine sedimentary systems and to begin to contrast and compare sediment budgets in different coastal areas. 

While the seafloor depths of the lysocline and CCD can be readily identified from sedimentary criteria, this information is of limited use without realistic knowledge of the rates at which calcium carbonate is lost from the sediments to dissolution. In practice, it is much easier to determine carbonate accumulation in the deep sea than it is to estimate carbonate loss. Yet the latter information is clearly needed in order to close sediment budgets and to reconstruct changes in the carbonate system.

Material may be supplied to the littoral sediment budget by coastal erosion, by feed from offshore or by contributions from rivers. After sediment has been distributed along the coast by longshore drift, it may be deposited in a sediment reservoir and, therefore, lost from the active environment. Sediment reservoirs formed offshore take the form of bars where the material is in a state of dynamic equilibrium, but from which it may easily re-enter the system. Dunes are the commonest types of onshore reservoirs, from which sediment is less likely to re-enter the system. 

In construction of a new inlet, the ebb and flood shoals can be assumed to be formed by sand transported from the adjacent beaches. Although this will be a long-term process, the volume removed from the beaches should be considered in the sediment budget.
