Filtration activity of mollusks Mya arenaria L. (Bivalvia) in estuaries of the southern Baltic Sea
This article argues that, in the estuaries the South Baltic, the bivalve molluscs Mya arenaria are capable of consuming an average of 6.5 % of the water body primary production. A numerical assessment of the filtration rate of these molluscs shows that they can filter daily an average of 2.41 ± 1.01 m3 of water per a square meter of the river bed. During the vegetation season, molluscs can clear approximately 380 m3 of water in estuaries removing up to 558....
The relations for potentials of filtration flows in media with common boundary and there employing for founded solutions some problems
The structure of filtration flows in two-dimensional laying media is studied. The definition of positive and negative flows is giving. The relations for complex potentials in media with common boundary are receiving. There are employing for founded solutions some problems....
Filtrational flows in the area, restricted by the sides of a rectangle
The article uses the method of spatial point reflection for the definition of complex potentials of filtrational flows in an area limited by
rectangle. The article considers possible conditions and generates solutions in the form of infinite series. For point source the series are presented by means of the Jacobi theta-function or the Weierstrass sigmafunction....
Potentials of filtration flows in an angle area
The new theorem which generalizing the theorems of a straight line and a circle is formulated and proved.With their help complex potentials of filtration flows in the two — component media filling angle area are received.
