The late Pleistocene in the Dead Sea Basin is one of the most studied and well-dated under-filled lacustrine deposits in the world and therefore provides a unique opportunity for analyzing individual controlling factors by applying field data into a forward model.
The analysis of the depositional history of basins commonly shows a nonunique solution caused by the interdependence of the depositional controlling factors. This can be demonstrated by modeling stratigraphic successions that were constructed using different sedimentary and tectonic values but visually look the same.
Here, we used the computer forward simulation SEDPAK to reconstruct the stratigraphic sequences observed in the field using multiple data sets that were established for these deposits. By applying a high-resolution lake level curve, subsidence history, and depositional rates in the offshore sections, we reduced the uncertainties of the model that match outcrop observations. We were then able to test the sensitivity of the simulated cross section to changes in individual parameters and evaluate the contribution of each of them to the result. This allows checking for errors and locations where more data are needed. It also provides insights into the distribution and character of potential hydrocarbon reservoir facies.

Lacustrine Sandstone Reservoirs and Hydrocarbon Systems
Many publications on lacustrine systems concentrate on reconstructing paleo-environments, deciphering paleoclimate or estimating hydrocarbon source potential. This is the first memoir to give attention to describing the occurrence, distribution and character of sandstones in various lake settings. the volume is the outcome of a Hedberg Conference held in Baku, Azerbaijan in 2004. The memoir is divided into four sections beginning with a global overview, and followed by two sections covering lacustrine systems in compressional and extensional regimes. The volume concludes with a series of papers on modern lake regimes.
