This EWN Action Project provides biological and hydrological monitoring data to quantify benefits and otherwise improve our understanding of the maturation of beneficial use of dredged material within the Atchafalaya Basin. The project documents how a river island is successfully created using dredged material in a beneficial manner, taking advantage of the natural hydrological processes inherent in the system. Project findings will help direct future dredged material placement practices in the basin and other riverine systems.
