Abstract: Conventional multilayered riprap and filter protections around bridge piers can be substituted by one thick single layer of riprap. Because of this simpler construction, field installations are less likely to be defective. ...

Abstract: Critical bed shear stresses for grains in a mixed-size bed are known to depend on the ratio between the size of dislocated grains and an average grain size for the bed. However, laboratory experiments with sediments ...

Abstract: A simple theory shows that the two-layer transport capacity of a constriction may be increased considerably by barotropic current fluctuations. This is confirmed by laboratory experiments. The effect may be of great ...

Abstract: Hovmöller diagram, a seemingly simple time-longitude construction, played a decisive role in the early development of computerized weather forecasts.

Abstract: This paper presents a dynamical model for the salinity and thickness of the upper layer in the Arctic. The parameters are the river runoff to the Arctic, the buoyancy supply through the Bering Strait, the export of ice ...

Abstract: A problem of great concern in precipitation measurements is the wind loss. This paper presents a new wind shield that reduces this loss. Tests of the new shield were made in a wind tunnel and in the field. The wind shield ...

Abstract: In an earlier paper (Stigebrandt, 1976), a model was proposed for internal wave-induced vertical mixing in a sill fjord. The observational evidence for the theory at that time was rather sparse, but the void is materially ...

Abstract: hristiansen and Ljungqvist have presented an extratropical NH temperature reconstruction using a method (LOC) that they claim ?preserves? low-frequency variability, at the expense of exaggerated high-frequency variability. ...

Abstract: The time-dependent vertical circulation of the Baltic Proper is modeled using a horizontally integrated model of high vertical resolution. A seasonal pycnocline model computes the properties of the mixed layer. Below this ...

Abstract: A one-dimensional seasonal pycnocline model, primarily intended for use in long-term circulation models, is developed. The model is of the two-layer (integral) type with a turbulent, well mixed surface layer and a nonturbulent, ...
