In recent times, reduced order models (ROM) techniques are increasingly used to improve the computational efficiency of simulation models. The Proper Orthogonal Decomposition (POD) method provides an orthogonal basis for representing a given set of data and constructing the ROM by means of the method of snapshots. In this work, a POD-based intrusive ROM strategy is applied to the 1D SWE. The main goal of this work is to build a simulation model able to reproduce realistic scenarios. We analyse the computational improvement and the accuracy of the ROM results with respect to those of the full-order model (FOM). 000124405 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/T32-20R$$9info:eu-repo/grantAgreement/ES/DGA-FSE/E24-17R$$9info:eu-repo/grantAgreement/ES/MICINN-FEDER/PGC2018-094341-B-I00 000124405 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000124405 592__ $$a0.199$$b2023 000124405 593__ $$aEarth and Planetary Sciences (miscellaneous)$$c2023 000124405 593__ $$aPhysics and Astronomy (miscellaneous)$$c2023 000124405 593__ $$aEnvironmental Science (miscellaneous)$$c2023 000124405 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000124405 700__ $$0(orcid)0000-0003-2538-9027$$aGracia, J.
