Bank Distress of Low Water Weirs on Big Creek, LA.
Abstract
Several recently constructed low water weirs on Big Creek in northeastern Louisiana have shown signs of bank distress (slumping of slopes and severe erosion). The weirs were evaluated to determine possible causes of the distress, recommend remedial measures, and recommend direction for future studies. The evaluation included visual inspection, discussions with design and inspection personnel, soil sampling and testing, and soil and pore water chemistry determinations. The distress problem was divided into two parts: an erosion problem (gradual removal of material beneath and adjacent to the downstream edge of the slope protection) and a bank distress problem (i.e., riprap and filter fabric displacement associated with apparent large soil displacements).
