- Abstract
Ecological restoration in the Reservation of Danube Delta Biosphere is a method of sustainable development of nature and local communities, for the medium and long term. The topography and structural variety of bed channels influence the hydraulic network and ecological restoration processes. To understand the general comportment of ecological restoration processes it is important to survey the channel from a bathymetric and topographic point of view. Modeling the ecological restoration processes commonly includes measures of water level, discharge, and velocity of channel transect. The present study aims to collect and analyze the topo-bathymetric survey data obtained for two periods for the channel Ivancea and Cordon Litoral, from the Reservation of Danube Delta Biosphere. This area was come under an ecological restoration phase by dredging it. The first survey expedition was made before the dredging (august 2021), and the last expedition was made after the dredging (after august 2021). The result shows that the use of modern method and equipment for the survey, ensure the highest accuracy for water circulation system data analysis. The data analysis highlights that ecological restoration increases the discharge and the water velocity. In conclusion, the dredging process is important for ecological restoration, in the context of deltaic systems. Also, the time-to-time monitoring of this process, let us understand the sedimentation rate, and how it influences the hydraulics overall.
