The specific project need which led to the development of CS2.NET involved the sizing of dredge spoil settling ponds. Since hydraulic dredging can generate large volumes of extremely loose fluid sediments, the needed settling pond or disposal dike size depends partially on how fast the material will settle and consolidate under its own weight. Most consolidation programs are limited to small strain consolidation situations such as those applicable to foundation design. The CS2 numerical model is well suited to model the 1-D large-strain settlement of very loose sediments under their self weight with or without a surcharge load and/or seepage forces.
