Universidad de Zaragoza (orcid)0000-0003-0846-6262 A POD-based reduced order model applied to 1D shallow water equations 2023 Access copy available to the general public Unrestricted Many environmental problems involving free surface flow can be solved using the shallow water equations (SWE) often involving high computational costs due to the large spatial and temporal scales of the events. 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). info:eu-repo/grantAgreement/ES/DGA-FEDER/T32-20R info:eu-repo/grantAgreement/ES/DGA-FSE/E24-17R info:eu-repo/grantAgreement/ES/MICINN-FEDER/PGC2018-094341-B-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 0.199 2023 Earth and Planetary Sciences (miscellaneous) 2023 Physics and Astronomy (miscellaneous) 2023 Environmental Science (miscellaneous) 2023 1.0 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gracia, J.
