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
Hampton-on-Sea dropped at Long Rock by an alternate normal east-west flow tide. When there are exceptional conditions on top of these tidal streams, for example a low pressure system causing higher water level coinciding with strong north-westerly winds, coastal flooding can occur. Hampton Brook, now Westbrook, reached the sea through a stone culvert but seaweed often blocked it, making it overflow and become stagnant. The land between the houses and the often-foetid Hampton Brook was low-lying enough to be subject to flood during a combination of spring tide, prolonged rainfall and onshore wind. Either the digging or the filling-in of the
