dc.description.abstractThe following study examines the occurrence of seepage incidents and sand boils observed and documented during the 2011 Mississippi River Flood in the Lower Mississippi River Valley (LMV) within the boundaries of the U.S. Army Corps of Engineers (USACE), Mississippi Valley Division (MVD), Vicksburg District. This study examines the occurrence of sand boils in relationship to the underlying floodplain geology and identifies locations where large sand boils occurred. Large sand boil areas will be the focus for additional detailed study to better understand the mechanics of underseepage and internal erosion in USACE flood-control levees. Seepage and sand boil incidents documented during the 2011 Flood are presented in this report on geologic base maps and pre-flood imagery to compile a record of their occurrence and identify geologic relationships, as well as spatial patterns associated with the underlying fluvial landforms. A review of levee evolution within the LMV is summarized here along with past research studies of seepage involving major historic floods and their control.en_US
