Sediment Transport On A River-Dominated Shallow Water Shelf: Atchafalaya Bay Region, Louisiana, Renee T. Bellotte
Sediment Transport On A River-Dominated Shallow Water Shelf: Atchafalaya Bay Region, Louisiana, Renee T. Bellotte
LSU Master's Theses
Cold front passage impacts on sediment transport on the inner continental shelf near Atchafalaya Bay were studied, combining satellite imagery and in-situ meteorological and oceanographic measurements. An empirical model relating atmospherically corrected MODIS imagery reflectance to surface measurements of suspended sediment concentration was developed and successfully applied to the coastal waters. An equation for predicting total suspended sediment from Nephelometric Turbidity Units was also applied to the water column at 1, 2, and 3 meters from the seabed. Five case study weeks were selected to examine the dynamics of pre-frontal and post-front forcing mechanisms on sediment transport in a fine-grained …

The Hydrology And Sediment Transport Of Low-Gradient, Forested Headwater Streams, Philip Saksa
LSU Master's Theses
Understanding stream hydrology of headwater regions is critical in effective land management for downstream water quantity and quality. Although extensive research has been performed on headwater streams in topographically variable areas, fewer studies examine low-gradient headwater stream systems, such as those existing on much of the southeastern coastal plain. This study aims to investigate spatial and temporal variation of headwater stream hydrology in a low-gradient forested watershed, quantify mass loading of suspended and dissolved solids in the watershed, and assess the applicability of a spatially distributed model in predicting hydrologic responses of a flat terrain landscape. Stream discharge and sediments …
