Description
Das im folgenden erläuterte Verfahren beruht auf i. dem Unterschied der spezifischen Gewichte von Süß- und Salzwasser, 2. der größerenAdhäsion von Süßwasser an feste Körper gegenüber dem spezifisch schwereren Salzwasser, 3. den unterschiedlichen Filtergeschwindigkeiten der verschiedenen Bodenformationen, :I. dem statischen Druck und dem Gesetz von Pascal für Flüssigkeiten.The method explained below is based on i. the difference the specific gravity of fresh and salt water, 2. the greater adhesion of fresh water to solid bodies compared to the specifically heavier salt water, 3. the different ones Filter speeds of the various soil formations: I. the static pressure and Pascal's law for liquids.
Infolge obergenannter physikalischer Grunderscheinungen schwimmt das auf den Inseln und in den Küstengebieten versickernde Niederschlagswasser auf dem in die Tiefe zuri.ickgedrängtetn Salzwasser. Durch anhaltende Zuführung von Süßwasser ist es möglich, das Salzwasser immer mehr in die Tiefe zu drängen.As a result of the above-mentioned basic physical phenomena, it floats on the islands and in the coastal areas seepage water on the Salt water pushed back into the depths. Through constant supply of fresh water it is possible to push the salt water deeper and deeper.
Bei den Inseln schwimmt das Süßwasser auf einem muldenförmig gebildeten Salzwasserspiegel. Diese Mulde hat ihre größte Tiefe in der Längsachse der Inseln und verläuft in der Querachse, der Drucklinie von Pascal folgend, im oberirdisch angrenzenden Salzwasser. Bei den Küstenrandgebieten schiebt sich der Salzwasserspiegel, ebenfalls dem Gesetz von Pascal folgend, unter das Süßwasser des Festlandes.With the islands, the fresh water swims on a trough-shaped Salt water level. This trough has its greatest depth in the longitudinal axis of the islands and runs in the transverse axis, following Pascal's pressure line, above ground adjacent salt water. In the coastal areas the salt water level shifts, also following Pascal's law, under the fresh water of the mainland.
Angesichts dieser Erkenntnis besteht das neue \"erfahren darin, daß den aus salzhaltigen Gewässern sich natürlich erhebenden oder künstlich geschaffenen Boden Süßwassermengen künstlich zugeführt werden, die infolge der eingangs aufgeführten physikalischen Grundgesetze das Salzwasser mehr und mehr in die Tiefe drängen und dabei gleichzeitig nach dem Gesetz von Pascal einen größeren horizontalen Druck gegen die muldenförmige Ward des umgebenden Salzwassers ausüben und dieses nach allen Seiten hin gleichmäßig fortdrücken. Der sich auf diese Weise ausdehnende Kern des Süßwasserbeckens bringt neue Sandanschwemmungen durch die Gezeiten mit sich, bringt verlorengegangenen Strand wieder zum Vorschein und verdrängt den sich an die Inseln und Küsten näher heranschiebenden Seewasserstrom. Gleichzeitig verleiht er den Inseln oder neu gewonnenen Landabschnitten die erforderliche Stabilität gegen Brandungen und Hochwassergefahren.In the face of this knowledge, the new \ "experience is that those that arise naturally or artificially from salty waters Soil amounts of fresh water are artificially fed, as a result of the initially listed physical laws push the salt water more and more into the depth and at the same time, according to Pascal's law, a greater horizontal pressure Exercise against the trough-shaped ward of the surrounding salt water and this after Press evenly on all sides. The core expanding in this way of the freshwater basin brings new sand alluvial with the tides, brings the lost beach back to the fore and supplants it the islands and coasts moving closer to the sea water flow. At the same time gives he gives the islands or newly reclaimed stretches of land the necessary stability Surf and flood hazards.
Die Zuführung des Süßwassers erfolgt in bekannter Weise mittels Versickerungsgräben und Schächte bzw. durch einfaches Auffüllen auf vorhandenes oder künstlich geschaffenes Gelände, wo es auf natürlichem Wege versickert.The fresh water is supplied in a known manner by means of seepage ditches and shafts or by simply filling up on existing or artificially created Terrain where it naturally seeps away.
In der Zeichnung sind in Fig.3 und .4 zwei Anwendungsformen zum Ausdruck gebracht.In the drawing are in Fig.3 and .4 two forms of application for expression brought.
Eig. i zeigt die Lagerung des Süßwasserbeckens b, das sich im Laufe der Jahre unter der Insel a angesammelt bat und muldenförmig auf dem von Salzwasser durchträtrktem Boden c ruht. Das Seewasser ist mit d bezeichnet.Prop. i shows the storage of the freshwater basin b, which is in the course of the years under the island a bat accumulated and troughed on that of salt water soaked soil c rests. The lake water is denoted by d.
Fig. 2 zeigt die Lagerung des Süßwassers in den Küstenrandgebieten at. Hier schiebt sich das Salzwasser jedoch nur von einer Seite, der Wasserdruckkurve entsprechend, unter (las Festland.Fig. 2 shows the storage of fresh water in the coastal edge areas at. Here, however, the salt water only pushes itself from one side, the water pressure curve accordingly, under (read mainland.
Fig. 3 zeigt die Abdrängung des Meeresstrornes, der sich zu weit an die Insel herangeschoben hat. Das alte Strombett st wird durch künstliche Zufuhr von Süßwasser z in ein neues Strombett s' abgedrängt.Fig. 3 shows the displacement of the ocean current, which is too far pushed the island up. The old stream bed is created by artificial supply displaced by fresh water z in a new stream bed s'.
Fig. .I zeigt die künstliche Bildung eines Brückenkopfes k, der auf der Insel i mit ihrer natürl:icben Strandgrenze x und der oberen Süßwasserspiegelgrenze y durch künstliche Zufuhr von Süßwasser gebildet wird und eine Strandgewinnung zur Folge hat.Fig .I shows the artificial formation of a bridgehead k, the the island i with its natural beach border x and the upper fresh water level limit y is formed by artificial supply of fresh water and a beach reclamation for Consequence.
