Application of 3D-Printing Technology in a Modified Oedometer for Characterization of Dredged Coastal Wetland Sediments

Published on 2026-02-03 by Omar S. Apu, Jay X. Wang @MDPI

Abstract: In Louisiana&amp;rsquo;s marsh creation projects designed to mitigate wetland loss, riverine sediments are hydraulically dredged and transported through pipelines. These dredged materials are extremely soft, with moisture contents well above 100%, resulting in significant consolidation settlements even under minimal self-weight loads. Conventional one-dimensional (1-D) oedometer consolidation tests are commonly used to assess consolidation behavior; however, they are limited to soils with mu[...]


Our summary: This study introduces a modified oedometer using 3D-printed dial caps to test high-moisture dredged sediments. The new setup reduces seating pressure, allowing for accurate testing of slurries with moisture contents over 100%. Results show that integrating settling column tests enhances the evaluation of consolidation behavior in these soils.
