Mathematical model of the Danube Delta Hydrographical Network Morphological Dynamics

Abstract

This paper presents an innovative technology used to investigate the Danube Delta Biosphere Reserve hydrographical network from the morphologic changes point of view, as result of fluvial processes, erosion and alluvial sedimentation. Field measurements and data processing are performed on water flow, sediment transport andbathymetry. Geospatial databases resulted help for constructing the mathematical /hydraulic model to simulate the hydro-morphological dynamics. There is used as workbench the Delft3D software – a product of DELTARES - Delft Hydraulic Institute, The Netherlands. The model results serve as practical tool for end users to scientifically justify the management decisions made on hydrographic network rehabilitation / reconstruction in order to improve the water flow regime
