ABSTRACT
Reservoir silting is a process of concern because of its implication on hydrologic management and sediment budget analysis. We have applied a classic methodology of subtracting initial and actual surveyed topography of reservoir bed in a GIS environment to assess the extent of the silting process for two reservoirs situated in the central part of the Moldavian Plateau (Eastern Romania), in Bahlui River Basin: Parcovaci reservoir and Ciurbesti reservoir. While both reservoirs have similar dimensions (discharge, catchment area, volume), the catchment physiographic conditions differ. Since the construction, both reservoirs have their gross volume half filled, although Ciurbesti reservoir it is twice older than Parcovaci, in the second reservoir catchment the volume of produced sediment being double than the first one. The sediment distribution reflect the shape of the reservoir bathymetry and the laws of sedimentation, with clear deltas and dam high sediment thickness. The sedimentation results is consistent with the trends cited in the literature for Moldavian Plateau.
