Sediment Processes and their Relationship to Various Sediment Environments
Environmental Characteristics
Key Fate and Transport Processes
Generally depositional environment
Groundwater interaction decreasing
Organic matter decreasing with
Often fine-grained sediment
Water-side mass transfer limitations
advection in near-shore area
Bioturbation (especially in near-shore area)
Diffusion in quiescent settings
Biotransformation of organic matter (e.g., gas
Low to high energy environment
Potential for significant groundwater
Variable sediment characteristics
Local and generalized groundwater
biotransformation processes in
sediments (potentially anaerobic at depth)
Generally low energy environment
