Abstract

A nonlinear optimization model is formulated for determining optimal reservoir releases to minimize channel bed aggradation and degradation in downstream rivers. The model is based upon minimizing channel bed elevation changes subject to constraints that define system hydraulics (i.e. continuity and energy), sediment routing and transport equations, operational constraints, and boundary conditions. The nonlinear programming problem is formulated as a discrete-time optimal control problem that can be solved using differential dynamic programming with the HEC-6 sediment model interfaced to solve the laws of motion.
