Based on a sample of 26 basins with control elements, we try to throw some light on this interesting subject. 2. Dynamic control Several control elements were found in aque- ducts which raises many questions: which functions did they execute and which mecha- nisms were used, was there any systematic approach in Roman times, is there any literary or epigraphic evidence about these actions.
