Small unsteady spoil banks/ levees can be built up to form a 'bowl' shape. Then with the help of dredges, soil can be pumped in and marsh grasses planted. Once the marsh grasses build up, levees will begin to collapse creating a new vegetated marsh area.
Worden is a village in Madison County, Illinois, United States.
Worden was originally called New Hampton, and under the latter name was laid out in 1860. When the railroad was built through the settlement in 1870, the name Worden was given to the station, after John C. Worden, an English immigrant, businessman, and railroad promoter.
