improved model stability or reduced run times which may reduce time costs for the modelling study. SEPA has licenses and skills in a number of modelling packages, Table 3-4, and may be able to review models or assist local authorities in viewing models and results and rerunning models if necessary. Some modelling packages either have free versions with limited functionality, or viewers available at a reduced cost when compared to the full license. Information on this is available from the relevant software suppliers. Table 3-4: Flood modelling software currently used by SEPA. 4 Formerly ISIS.
5 The MIKE suite is capable of modelling waves and hydrodynamic flows with estuaries, but SEPA’s flood risk teams do not currently have a license for this functionality.
