A conceptual runoff model is studied in this work. Especially the residuals of the model (the differences between the computed hydrograph and the recorded one) are examinated. The density function and the autocorrelation function of the residuals are estimated and tested.

The model must be …

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 …

A model was developed by Prych (1972) at SMHI for thermal pollution predictions. The model, which is a modified version of a model originally presented by Stolzenbach and Harleman (1971), is based on an integral analysis of a turbulent, bouyant, horizontal, surface jet into a large ,deep, uniform, …

Erfarenheterna av begreppsmässiga avrinningsmodeller vid Sveriges Meteorologiskaoch Hydrologiska Institut summeras i föreliggande arbete. Den grundläggande filosofin och metodiken vid utvecklingen av HBV-modellen diskuteras. Modellstrukturen beskrives med en presentation av den fysikaliska …

In the search for possibie sites for new nuclear power plants in Sweden a site on Bråviken, a narrow fjord, is being considered. A numerical hydrodynamic model has been developedt o predict the probable effects of the waste heat discharged into the estuary on the natural estuarine flow.

The model …

The application of the model in the Filefjell Basin led us to some conclution concering tho model structure and the relative importance of its parameters.

The original HBV-2 model had to be modified with the introduction of a third runoff component. A oompletely lumped modifioation proved to be …

Strömmätningar på flera djup i en vertikal i Sunninge sund utfördes under delar av 1971 och 1972. 1972 års mätningar har filtrerats så att strömmar med perioder omkring eller mindre än det halvdagliga tidvattnet tagits bort. Den resterande strömmen har lagts till grund för en beräkning av …

This report is an attempt to describe natural temperature variations around the Swedish coast. The data are collected partly from Swedish and Danish lightship observations, partly from measurements made by SMHI observers and recording instruments. The observational stations are concentrated around …

A model is developed by which the poison concentration due to a discharge of toxic matter in the coastal water is calculated. The outlet arises from a hypothetical accident to a ship loaded with dangerous materials. The oceanographic conditions are assumed to be mast unfavourable for a rapid …

Reported are diverse efforts to verify, or test the accuracy of,a numerical model for thermal pollution predictions. The model,developed by Prych (1972) at SMHI, is an integral analysis ofa buoyant, turbulent surface jet. The program. is slightly revised,and effects of the changes are presented.
