South Aral Sea Syr Darya, would be diverted in order to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea was split into northern and southern parts; the northern part is the current North Aral Sea. In 2007, the western basin had a salinity of 70 g/l and the eastern basin 100 g/l. Once the water level falls below the connecting channel (elevation 29 m), the salinities can be expected to diverge further. Under current conditions, the eastern basin may receive water from the Amu Darya in wet years, fluctuating in
Sea level equation the sea surface constant for a specific deglaciation chronology and viscoelastic earth model. The SLE theory was then developed by other authors as Mitrovica & Peltier, Mitrovica et al. and Spada & Stocchi. In its simplest form, the SLE reads where formula_2 is the sea–level change, formula_3 is the sea surface variation as seen from Earth's center of mass, and formula_4 is vertical displacement. In a more explicit form the SLE can be written as follow: where formula_6 is colatitude and formula_7 is longitude, formula_8 is time, formula_9 and formula_10 are the densities of ice and water, respectively, formula_11 is
