Sediments and Ecohyraulics is comprised of papers submitted to the 6th International Conference on Cohesive Sediments (INTERCOH 2005) held in Saga, Japan, September 2005. The papers are divided into two major categories. The first is basic processes, including erosion, settling, flocculation, and consolidation. The second major catagory is application of the understanding of cohesive sediments to address specific issues, including waterway and part management, fluid mud behavior, and contaminiated sediment management.

*Provides an up-to-date resource of the present knowledge of cohesive sediment transport processes
*Contains practical solutions on cohesive transport problems
*Presents information on managing cohesive sediments
