Abstract
A model to simulate the time evolution of river delta formation process
is presented. It is based on the continuity equation for water and
sediment flow and a phenomenological sedimentation/erosion law.
Different delta types are reproduced by using different parameters and
erosion rules. The structures of the calculated patterns are analyzed in
space and time and compared with real data patterns. Furthermore, our
model is capable of simulating the rich dynamics related to the
switching of the mouth of the river delta. The simulation results are
then compared with geological records for the Mississippi River.
