Simulating Marine Sedimentation Using Streamlines
in: 24th gOcad Meeting, ASGA
Abstract
This paper presents a three-dimensional simulation model for erosion, transport and deposition of clastic sediments in a marine environment. Erosion and deposition of sediments on the seafloor are represented by the means of empirical formulations parameterized by field data. The key parameters are : (i) the flow of suspended sediments invading the zone of interest and transported by marine currents; (ii) the granulometry distribution of clastic material; (iii) the velocity field of submarine currents. The G°CAD streamline research plug-in for triangular surfaces has been used to solve the coupled sedimentation/erosion/transport equations. Transport of suspended sediment is calculated including diffusive, dispersive and advective components and solving the differential equations by a finite element methods. Deposition of suspended clastic sediment matter is calculated as a function of velocity, water depth and granulometry. The model was tested and calibrated by simulating flows and suspended sediment transport in simple illustrative cases.
