Earth/River-meandering

In this paper I briefly introduce Earth meandering concept in order to understand river meandering. This is a fundamental concept which helps us to understand how big river initiate and disappear. Friction difference between North-Pole(NP) and South-Pole(SP) applies twisting field around Geodynamic-Pole (GP/Kaaba) symbolized as Global Forward Sigmoid (GFS) and Global Retard Sigmoid (GRS), NP is a global inflection point of the Earth and Tectonic Pole(TP) is a splitting point of East/West-Continents. There is a physical relation between NP/TP-Distance (d), friction coefficient (fc) and average of height difference between oceans and lands (h) defined as d≈h/2fc Edward and Smith (2002). Based on geomorphological evidence, (d) is about 1600 Km and h≈6 Km, so fc≈0.0025. GFS&GRS arise in the Earth due to Earth-Rotation and Earth-Inertia respectively. These curves are components of '8'-like curve (i.e. 'S' and 'Ϩ'). Rolling and backrolling ('S' and 'Ϩ') deform the Earth's crust as cubical fracture zone, Danube-River and Volga River meandered along vertical component of triple junction of these cubical fracture zone Fig. 3. Kaaba is a first cube (house-like) build in the Earth due to tectonizm. It seems North America-Australia and Eurasia-South America has global CCW rotation around Kaaba and local CW inertia drive around itself. Although four vertex of this rectangle rotated CW but the sense of local inertia drive between east and west operate is opposite phase (due to 180 degree difference between east and west). As the universe spreads out in the space Earth's material also rolls forward (Dahw) from one side and rolls backward (Tahw) from other side. Interaction of these couple rolling (GFS&GRS) shrink continents from peripheral i.e. dissolve old continental crust from the oceans and accumulate them in the land also structurized the Earth fractaly from big scale (core, mantel and crust) till mineral. Dahw(rolling)&Tahw(spreading) are original words mentioned in Holy Quran for earth description Asadiyan and Zamani (2010). Tahw follows Dahw therefore oceans (or Earth Tahwing) are created due to Earth Dahwing (orogenies) and not other way around as is in the Plate Tectonics Model (PTM). Atlantic Ocean and its symmetrical magnetic anomalies formed due to easterly rolling and westerly rolling. This unified model not only supported by geomorphological evidences but also by volcanic, seismic, as well as magnetic and gravity. In this model all information that we achieved in small scale are applicable in big scale. Rivers meandering is small scale of Earth Dahwing/ Tahwing dynamics e.g. in mountainous region or Dahw-ed region rivers meander in sharp bends with smaller wave lengths but in flat region or Tahw-ed region become flat and smooth with bigger wavelengths, in the most Tahw-ed region, Atlantic and Pacific Ocean meandered in global scale i.e. Pacific Ocean meandered in order-0 around 'O'-ring but Atlantic meandered in order-1 around '8'-ring(Mobius Strip). In the rivers we see sediment transfer from concave/outer shore and accumulated in the convex/inner shore due to deceleration in the vortex current, it seems transformation of material from oceans and concentration in the continents also occur due to deceleration of angular velocity from center to peripheral of each fractal domain. Galaxy-model well fitted with this dynamics; in Galaxy-model peripheral materials have retrograde motion with respect to the central bar.
