henning filip hjulström -lrb- 6 october 1902 -- 26 march 1982 -rrb- was a swedish geographer .
hjulström was professor of geography at uppsala university from 1944 , and in 1949 , when the subject of geography was split , he became professor of physical geography .
filip hjulström 's doctoral thesis , `` the river fyris '' , contained one of the first quantitative studies of geomorphological processes ever published .
it was a study of sediment transport and soil erosion in the drainage area of the river fyrisån , based on a daily water sample that he took as he passed on the way to the department , and analyzed for suspended sediment content .
his students followed in the same vein , making quantitative studies of mass transport -lrb- anders rapp -rrb- , fluvial transport -lrb- Åke sundborg -rrb- , delta deposition -lrb- valter axelsson -rrb- , and coastal processes -lrb- john o norrman -rrb- .
this developed into `` the uppsala school of physical geography '' .
hjulström is most known for creating the hjulström curve , which describes the thresholds for erosion and deposition of particles in running water .
