In this paper, we report our work on applying Krylov iterative methods, accelerated by parallelizable domain-decomposed (DD) preconditioners, to the solution of nonsymmetric linear algebraic equations arising from implicit time discretization of a finite element model of the shaliow water equations
## Abstract A new conservation law is derived from the inviscid shallowβwater equations. This law governs the spreading of a fixed quantity of fluid. The symmetries of the Lagrangian of shallowβwater flow are determined. The links of these symmetries to the new law and to other conservation laws ar
