The Atchafalaya River Delta. Report 2. Field Data. Section 3: Grain Size Analysis of Selected Bay Sediments

Abstract

The Wax Lake Outlet and Lower Atchafalaya River deltas in Louisiana have grown dramatically. Concern for the impact of this growth has led the US army Corps of Engineers to conduct an investigation to predict how the deltas will evolve over the next 50 years and to determine the impacts of that growth on navigation, flood control, salinity, and sedimentation. This documents field and laboratory studies and analysis on the gradation of selected bay sediments. Core and grab samples were taken by Louisiana State University and returned to WES for geotechnical testing and analysis. This section emphasizes the grain size analysis of approximately 325 samples taken within the bay system and tributaries. The results of this analysis ultimately became the data for several of the numerical model studies conducted and reported within this series of reports and other independent studies conducted at LSU under contract with the New Orleans District. Keywords: Louisiana deltas; Sedimentology; Mathematical models; Flood control; Salinity.
