Audiomagnetotelluric investigations of shallow sedimentary basins in northern Sudan

Fast and Slow Compaction in Sedimentary Basins

A mathematical model of compaction in sedimentary basins is presented and analyzed. Compaction occurs when accumulating sediments compact under their own weight, expelling pore water in the process. If sedimentation is rapid or the permeability is low, then high pore pressures can result, a phenomenon which is of importance in oil drilling operations. Here we show that one-dimensional compactio...

Adaptive Resonance Theory Based Sedimentary Basins Identification

The objective of this paper is to present identification and recognition of Magneto-telluric data for sedimentary basins using Adaptive Resonance Theory (ART). Several sets of data consisting of 17 phases and 17 apparent resistivity values and their respective tag values are given. These sets of data are used for training the network, and other sets of data are used to test the network. The tes...

Experimental and Theoretical Study of Strata Formation in Sedimentary Basins

The long-term goals of our stratigraphy project are to obtain experimental evidence and to develop quantitative models of the formation of strata on continental margins. Experiments and analytical models can greatly contribute to better understand the relationships between variation in forcing functions such as sediment supply, sea-level changes and subsidence, and the resulting strata in depos...

Mathematical Modelling of Compaction and Diagenesis in Sedimentary Basins

Scale-invariant topography and porosity variations in fluvial sedimentary basins

We consider a model of • floodplain evolving with channel •vulsion, deposition, •nd erosion. Avulsion is modeled as • r•ndom process in sp•ce and time. Sediment ransport is modeled by the diffusion equation (Culling's model). The power spectrum of v•ri•tions in the topographic profiles predicted by the model S(k) is proportional to k -2 (where k is the w•venumber). This is the Brown noise often...
