This paper presents the findings of the mapping and evaluation of macrophyte vegetation from Tataru and Uzlina lakes, located within Danube Delta, Romania. Throughout time, the Danube Delta unique ecosystem has endured considerable ecological changes due to natural and anthropogenic stressors. Currently, the potential threats are those related to pollution, agriculture, land use, climate change and subsequently, the proliferation and/or the extinction of many macrophyte species. The excessive development of aquati...

This paper aims to assess the trend of river morphological evolution and changes in the Danube riverbed sector, i.e., Ceatal Izmail, using GIS techniques. The sector is located on the Danube at Mile 43, where the river branches into Chilia and Tulcea tributaries. Therefore, three monitoring topo-bathymetric profiles (2018 and 2019) were performed on Danube (Mm 43), Chilia (Km 114) and Tulcea (Mm 42.5), under circumstances of high and low water levels. On the Danube (Mm 43), an asymmetry of the valley (right bank) ...
