Tillämpning av en numerisk modell på Vänern (Swedish)
Abstract [en]

Current, temperature and water-level measurements in Lake Vänern from two epdisodes in 1971, representing a stratified resp anunstratified situation, have been used for the verification of an multilayer hydrodynamic model. Concentrating on wind-driven lake circulation it is shown that, aside from the currents along the western shore of the eastern basin, the correspondence between model results and observations is satisfactory. The computed currents could therefore be used for studies on the transport and dilution of wasterwater in the lake. It is also concluded that neither avariation of model parameters nor an increased vertical or horizontal resolution will make the model reproduce the strong and mainly south-going current along the western shore of the eastern half of the lake.

Abstract [sv]

Verifiering av en flerlagers hydrodynamisk modell tillämpad på Vänern har utförts med hjälp av ström-, temperatur- och vattenståndsvärden från två perioder 1971 (representerande skiktade resp oskiktade förhållanden). De beräknade strömmarna visas stämma väl överens med observerade data och bör därför kunna utgöra ett bra underlag vid studier av transportvägar och utspädningsgrad för olika typer av utsläpp. De relativt starka strömmarna i västra delen av Värmlandssjön har inte kunnat beskrivas i modellen trots försök med flera kombinationer av modellens parametervärden och ökad horisontell och vertikal upplösning.
