Wiebeking , educated technically as versatile as furthermore historically interested, found his first employment in Dusseldorf in 1788 as hydraulic engineer of the grand duchy Berg, but changed soon into Hessian, Austrian and finally Bavarian service. Already in 1818 he left everyday business to dedicate himself completely to his publications. However,

“ the priority of his activity (was) doubtless the field of hydraulic engineering … (He) demanded the creation of public hydro-technical research institutes … A lot of time was devoted by W. to cartography … ”

(Allgemeine Deutsche Biographie LV, 659 ff.). – And Zögner, Kartenschätze, p. 157 :

“ … one of the most able and productive personage of map affairs of his time and together known water and road architect . ”

Important works are i. a. the construction of a new harbour for Lindau (Lake of Constance) and the first larger correction of the River Isar near Munich. Besides expert opinions for flood protection and construction of two harbours in St. Petersburg, for the enhancement of the harbour conditions of Venice, Trieste and Nieuwendiep in Holland. He rejected, however, the construction of the Ludwig Canal connecting the Rhine with the Danube for his thorough conviction and in the discernment of the advantage of the upcoming railways.
