Abstract: A geomorphic assessment was conducted for the Pass a Loutre and South Pass deltaic channels of the Mississippi River birds-foot delta. The purpose of the study was to document long-term morphological trends in the channels through the analysis of historical stream gage data, hydrographic surveys, dredge data and other information on anthropogenic activity in the study area. The physical limits of the study were from Head of Passes to the Gulf of Mexico outlet for both passes, and the time period was focused from 1960 to 2008. Specifically, the geomorphic assessment tasks consisted of data compilation, a geometric data analysis, analysis of stage and discharge data, and assessment of historical river engineering activity in the study area. The results of all analyses were integrated to develop an understanding of the morphologic trends in the study area. Information derived from the geomorphic assessment assists in evaluating potential activities in the area such as river diversions for freshwater marsh restoration.
