Lacustrine Environments
Lacustrine environments may form part of a future ERGO phase or update.

Lacustrine siliciclastic sediment is transported by fluvial systems (as shown above with the Saskatchewan River flowing into the Cumberland Lake, Canada), either by suspension or bedload; however, glacial sources are important for higher latitude lakes, whilst wind-blown sand and silt contribute to fill in arid climatic regions. Basin morphology and basin size also play a part in the distribution of siliciclastic material, with the morphology governing the topography of the source area and the slope and bathymetry of the lake itself, whilst the basin size and orientation affects the occurring wave related processes.
