“…During the depositional time of the Red Palaeosol parent material, from 80 to 55 ka, sand was deposited on the coastal plain of Israel in a thickness ranging from 2 to 40 m (Zilberman et al, 2007;Roskin et al, 2013), forming dunes and sand sheet complexes. Since stream energies were greater during periods of low sea levels, mainly due to higher gradients and incisions (Suter and Berryhill, 1985;Anderson et al, 1996;Blum and Tōrnqvist, 2000 and ref. therein), the streams limited sand deposition in their channels, consequently transporting the sand back to the coastline where it was deposited.…”

The stratigraphic architecture of coastal plains is determined by the interactions between local (e.g. fluvial processes and topography), regional (e.g. climate) and global (e.g. sea level) forcing factors, primarily during the Late Quaternary Period. Detailed stratigraphic and sedimentological analyses of boreholes, cored between coastal ridges in the lowlands, coupled with optically stimulated luminescence (OSL) dating, and integrated with existing onshore and offshore databases, has enabled a 4-D reconstruction of the evolution of the coast of Israel during the last glacial-interglacial cycle. This model revealed that Nilotic-sourced littoral sand, intermittently transported inland by wind, has either been lithified into aeolianite or pedogenized into orange-brown palaeosol from about 100 ka to 8 ka. Dark silty clay wetlands were deposited between the aeolian coastal ridges adjacent to streams which cut the Israeli coastal plain and flow westward, from the Last Glacial Maximum until the onset of the Holocene. These units are topped by beach and aeolian quartz sand dated to 6.6-0.1 ka. Diachronous thicknesses and lithological dissimilarities were identified between the sections studied and previous reports on adjacent coastal aeolianite ridges. Streams were found to be a dominant control on the stratigraphical composition and related facies architecture due to fluvial-induced erosion. Consequently, the relief variations between the lowland and cliff controlled aeolian pedogenesis as well as alluvial processes from about 80 to 5 ka. Climate, mainly influenced by precipitation and dust input, induced pedogenic processes; while sea level lowstand during the Last Glacial Maximum is shown to have hindered sediment deposition in the shallow offshore, which in turn affected aeolian transport, reducing sediment accumulation on the palaeo-coastal plain. The palaeoenvironmental model presented in the current study serves as an example for understanding the evolution of similar low-latitude siliciclastic-rich low-gradient shelf-coastal areas during the last glacial-interglacial cycle. Furthermore, it demonstrates the influence of local to global forcing factors on these environments.

“…In many cases, these are depositional records, preserved in areas of relatively large sediment supply. Examples include, but are not limited to, the inner shelves of New Jersey (Sheridan et al, 2000), Maryland (Toscano, 1992;Toscano & York, 1992), North Carolina (Boss et al, 2002;Riggs et al, 1995), large estuaries (Colman et al, 1992) and thick sections on the Texas shelf (Anderson et al, 1996;Rodriguez et al, 2000). Where sediment supply is more limited (such as the shelves of South Carolina and Georgia), extensive recycling of shelf sediments during multiple Quaternary transgressions is inferred from local stratigraphic sections where 1-2 m of preserved section may represent the entire Quaternary (Gayes et al, 1992;Harris et al, 2000;Heron et al, 1984;Hine & Snyder, 1985;Macintyre et al, 1978;Pilkey et al, 1981).…”

“…Thus, variation in sediment flux caused by climate change or tectonics can be assessed on the basis of deviations from the template if other external forcing mechanisms are constant or change in (roughly) the same way as they did in our experiments. We illustrate the application of the template on the basis of the Colorado river-shelf system of Texas (Gulf of Mexico), which has been studied extensively in the last decades (Anderson et al, 1996(Anderson et al, , 2004. The Colorado River is fed by a drainage basin of 110 000 km 2 (Fig.…”

Variation in sediment transport and temporary sediment storage at large spatial and temporal scales is governed by inherited relief and by the interaction between climate change (water discharge and sediment yield), eustatic sea-level change and tectonics. These processes influence the character of sedimentary successions, and are difficult to reconstruct from stratigraphy alone. Physical modelling can help by allowing observation and quantification of processes that generate model stratigraphy. Sediment transport in the model set-up shows diffusive behaviour. Non-dimensionalizing the relevant physical parameters that underlie model stratigraphy allows a comparison with real-world examples. The effect of (changes in) the forcing parameters (discharge, sediment yield, sea-level change and consequent shoreline position) on a loose bed of sand in a set of experiments is measured by means of high-resolution digital elevation models (DEMs). These DEMs are transformed into geological maps, profiles and Wheeler diagrams that allow detailed reconstruction of sediment flux and routing, storage time, and headward erosion rates. All raw data are stored in the Pangaea database, and are publicly available. A synthesis of all experiment results obtained over the past 10 years has resulted in a first-order prediction of sediment flux that is induced solely by sealevel change. The flux changes with relaxation time (response time) of the system, transport efficiency of the river system (in terms of slope gradient), and the amount that sea level drops below the shelf edge (change in slope gradient); all variables are dimensionless. The results are presented as templates covering systematic trends in the effects of the dimensionless parameters on stratigraphic architecture, which allows for the assessment of the impact of sea-level change on sediment flux relative to the other forcing parameters.
