Sediment Retention

The InVEST Sediment Retention model estimates the capacity of a land parcel to retain sediment by using information on geomorphology, climate, vegetative coverage and management practices. A land parcel’s estimated soil loss and sediment transport informs the service step of the InVEST model, which produces outputs in terms of avoided sedimentation. The model can also value the landscape in terms of water quality maintenance or avoided reservoir sedimentation and determines how land use changes may impact the cost of sediment removal.
