Construction of water storage lakes, necessary for different uses (irrigation in agriculture, water supply for population), implies sizing of the facility so that it can permit the transition of flood flows that could happen on the river where the water storage lake is positioned (built). Such a water storage lake is dimensioned, according to normative standards, for a flood which corresponds to a certain probability calculation. Taking into account the fact that frequently from the moment of finishing the constru...

The purpose of this paper is to present the flood hazard maps using 2D hydraulic modeling. Many economic, social, environmental losses as well as casualties, occur annually due to floods [4]. To reduce the risk of hazard, flood hazard and risk maps are required for different probabilities of their production and creating models that can predict floods in production time, based on information received from sensors located on watersheds. Very important for an effective management against floods have become nonstruct...

Along Bistrita River in the Eastern Carpathians is produced each year freezeup ice jams. Depending on the hydro and weather conditions these breakup jams have a larger or smaller spreading. Periodical ice jams cause damage and noticeable loss of lives. The article examines the area between the tail of Mountain Spring Lake (Poiana Largului) and Dorna Arini which has a length of about 80 km. Jams and ice accumulations occur usually in the downstream section between Poiana Largului and Borca. It would be preferable f...

Protected areas have been created to limit or remove the man and nature harmful intervention on the existing flora and fauna. The research work has been focused on a protected area from Dobrogea, where there is an acute need for intervention, in order to save the existing rare species of plants. A permanent monitoring of the evolution of these species and other floral species must be done permanently, to see the effect of invasive species on rare ones. Effective monitoring of the studied area has been carried out ...
