Example of how Anthropogenic Actions can Impact Sediment System For Example?, a beach may erode naturally by the forces of waves and currents. Prior to development this beach might receive sand to replenish that lost from the nearshore but the following anthropogenic actions may inhibit natural restoration of the beach:

• Dams limit sediment supply to the open ocean and thus the beach
• Sediment sinks such as inlets (natural and constructed) capture sand and eliminate from system
• Jetties or groins impound sediment and act as barriers to limit alongshore transport of sediment
