Popis:	Uspoređeni su i vrednovani numerički 2D model plitkih voda obrađen softverom Stripp12 i 3D Navier-Stoksov model dvofaznog strujanja sa slobodnom površinom obrađen softverom Fluent. Kao test-primjer upotrijebljen je standardni laboratorijski eksperiment rušenja brane definiran u sklopu međunarodnog CADAM projekta. Analiza dobivenih rezultata pokazuje da rušenja oba modela daju visoku točnost rezultata, s time da se 3D model strujanja sa slobodnom površinom pokazuju točnijim. The numerical 2D shallow water model developed using the Stripp 12 software, and the 3D Navier- Stokes two-phase free-surface flow model based on the Fluent software, are compared and evaluated. The standard laboratory dam collapse experiment, defined in the scope of the international CADAM project, was used as a test example. The analysis of results shows that highly accurate failure results have been obtained for both models, although the 3D free surface flow model has proven to be more accurate.
