Applying the Von-Neumann stability analysis, the present method is shown to be unconditionally stable. The accuracy of the proposed method is checked by two test problems. L<inf>2</inf> and L<inf>∞</inf> error norms and conserved quantities are given at selected times. The obtained results are found in good agreement with the some recent results. © 2016 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/openAccessCollocationFinite Element MethodKawahara EquationSeptic B-SplinesSolitary WavesArticle10.19139/soic.v2i3.742-s2.0-85006351951
