Exploring The Role Of Near Channel Geospatial Attributes To Predict Suspended Sediment Concentration Patterns Across The Conus Region, Aaron J. Sigman
Exploring The Role Of Near Channel Geospatial Attributes To Predict Suspended Sediment Concentration Patterns Across The Conus Region, Aaron J. Sigman
All Graduate Theses and Dissertations, Fall 2023 to Present
High concentrations of suspended sediment (SSC) in a river can represent a critical water quality concern, reduce the storage capacity of reservoirs, and impact aquatic habitat. The total amount of sediment is calculated from a combination of river properties, including the amount of available sediment and the flow of water carrying the sediment. Water flow properties can be found using local information about the channel, however understanding the concentration of sediment in the river requires understanding the supply of sediment from the watershed. To understand where sediment is coming from, we examined over 1000 United States Geological Survey sites with …
Investigating Gulf Coast Aquifer System: Stratigraphy Reconstruction, Inverse Modeling, And Groundwater Stress Assessment, Shuo Yang
LSU Doctoral Dissertations
The Mississippi Embayment aquifer system (MEAS) and the Coastal Lowlands aquifer system (CLAS) provide substantial groundwater resources for human activities in the U.S. Gulf Coastal Plain. However, the overexploitation has led to groundwater depletion in the MEAS and the CLAS, threatening sustainable groundwater use. Such concern highlights the crucial need for an advanced understanding of stratigraphy and groundwater in these aquifer systems, which is essential for effective regional groundwater management. This dissertation presents a comprehensive investigation of MEAS and CLAS in the Louisiana and southwestern Mississippi region, encompassing three fundamental dimensions: stratigraphy reconstruction, groundwater modeling, and groundwater stress assessments.
