A method for solving the water quality models by a shooting technique was presented for Jamaica Bay. The technique exhibits excellent convergence rates for linear problems and generally involves the solution of much smaller linear systems than models utilizing direct finite difference methods. The method, which has been extended to multiconstituent water quality problems, has also been employed in the determination of water quality management policies in Jamaica Bay. A recent study has shown that these shooting techniques may also be employed in solving boundary value problems in which the elliptic operator is approximated with sparse two-dimensional finite difference equations with a considerable reduction in the size of the linear systems to be solved.
