Optimal allocation of ’BOD’ loadings in a tidal river Jamal, Iqbal Badrudin
A methodology Is presented in this thesis which addresses the water quality manager's problem of maximizing the biochemical oxygen demand loadings in reaches of a tidal river, subject to dissolved oxygen concentration regulation at various compliance levels. The non-linear tidal dynamics and BOD-DO processes were explicitly accounted for by numerical, finite-difference models incorporated as equality and inequality constraints of a non-linear programming problem solved by a direct search algorithm. This methodology was applied to the Nicomekl River in Surrey B.C., to investigate policy implications and its applicability, using a microcomputer, to the resolution of actual pollution management problems.
