Abstract: |
By introducing the variational adjoint method to the inversion of initial boundary values and parameters of the one-dimensional shallow water model, the related adjoint equations and adjoint conditions are deduced. And the procedure of the inversion method is presented step by step. Results of a numerical pilot example show that the method is feasible and effective, |
Key words: one-dimensional shallow water model variational adjoint inversion velocity water level |
