Basic equations of continuity, momentum conservation and the transport of turbulent kinetic energy per unit mass and its rate of dissipation are solved by using the finite volume numerical method. Several practical flow computations are shown: a steady flow in the Idrijca River narrow, a 2D flow of the Savinja River in the city of Laško and an unsteady dam-break flow in the sudden expansion and tidal flow in the system of three Mexican Pacific lagoons - Jitzamuri, Agiabampo and Bacorehuis. The comparison between the computed results and the field measurements or the physical models showed satisfactory agreement</dc:description><dc:description xml:lang="sl">Najprej so opisane teoretične osnove dvodimenzionalnih (2D) globinsko povprečnih modelov PCFLOW2D in PCFLOW2D-CURVE. Temeljne enačbe kontinuitete, ohranitve gibalne količine ter transporta turbulentne kinetične energije na enoto mase in stopnje mjene disipacije so rešene s pomočjo numerične metode končnih volumnov. Prikazanih je več primerov izračuna tokov; stalni tok v ožini reke Idrijce, dvodimenzionalni tok reke Savinje v Laškem, nestalni tok po porušitvi pregrade v hipni razširitvi in tok zaradi plime in oseke v sistemu treh mehiških pacifiških lagun Jitzamuri, Agiabampo in Bacorehuis.
