The Marsh Equilibrium Model MEM 5.41
Computes C-Sequestration and Marsh Responses to Sea-Level Rise
The one-dimensional or point version of the Marsh Equilibrium Model provides a beautiful example of how a salt marsh plant community interacts with the physical environment to perpetuate its environment in such a way as to favor its survival (within limits). Call it salt marsh Gaia if you will. MEM 5.4 is the successor to the Morris et al. model published in 2002. New to MEM 5 is a more explicit treatment of belowground organic matter and the incorporation of the sediment cohort model SEMIDEC (Morris and Bowden 1986). This online version allows users to perform sophisticated experiments (see the exercises page) and to simulate sedimentation and sediment organic matter profiles in any tidal marsh.
