Abstract:
The Amite River Basin (ARB) in southeastern Louisiana has experienced numerous hydromodifications because of land use-land cover (LULC) changes. Mining in the middle section of the river began in the 1920s and continues until present, creating significant hydrological and environment challenges, especially during flood events. The goal of the research aims to study the fluvial instability due to the flood and mining practices. Using the level set method, this study examines how the 2016 flood changed the pits’ size and depressions hierarchy in the floodplain and how the spatial variation pit size and numbers, and thus mining influence, varies spatially. The study also examines planform change after the 1980s using a variety of channel change indices. This study examines how land cover-land use (LCLU) contributes to the channel instability and the strength of the correlations. The results indicated a positive correlation between mining practices and river instability. Also, the results indicated the flood event played important role in the river avulsion. Findings of this study are relevant to better understanding drivers and extent of channel instability
