| Abstract: | The Red River, Atchafalaya River, and the Old River Control Complex (ORCC) Outflow Channel Adaptive Hydraulics two-dimensional depth averaged sediment model (AdH-2D-SED) was used to evaluate the short-term and system-wide sedimentation effects of modifying the operation schedule at ORCC. The changes evaluated were increasing and decreasing the percentage of flow that is diverted to the Atchafalaya River from the Mississippi River at the ORCC and modifying the distributions through four ORCC structures. Sedimentation effects for several operation scenarios were compared to a Base condition for each water year that represented the existing operation protocols. Four dredging scenarios were developed and analyzed. Additionally, two structure options were developed and analyzed. The scenario analyses presented in this report are intended to identify large trends and to make gross assessments of the potential impacts of various proposed operational changes to the ORCC. |
