List of Famous people with last name Tulla

Johann Gottfried Tulla was a German engineer who accomplished the straightening of the Rhine, improving navigation and alleviating the effects of flooding. His measures gave the Upper Rhine a completely new appearance. The river was deepened and channelled between embankments which narrowed the channels to a width of 200 to 250 m ; new sections were dug to straighten out its meandering course, and numerous small islands were removed. The effect was to reduce the river's length between Basel and Worms from 355 to 275 km. However, the straightening of the Upper Rhine had increased the streaming speed and thus permanently raised the flood risk in the regions of the Middle and the Lower Rhine, partial floodplain restoration is still performed in a joint program of Germany and France.
