Hans-Åke Nordström Hans-Åke Nordström Hans-Åke Nordström (born c. 1934) is a Swedish archaeologist and professor at Uppsala University. His work has included excavations in parts of Nubia, submerged since the construction of the Aswan Dam, and the development of the Vienna System for classifying Egyptian pottery. Hans-Åke Nordström was born around 1934. During the 1960s he excavated parts of Nubia, an area between Aswan in Egypt and Khartoum in Sudan, which were submerged following the construction of the Aswan Dam. In 1972 he received his Ph.D., on the basis of his thesis "Ceramic Ecology and Ceramic Technology. Early Nubian Cultures from the
Aswan Dam soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields. Drainage through sub-surface drains and drainage channels is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2.0 million have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $3.1 billion. Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. This
