The research was carried out to examine the influence of tributary inflows on the hydrochemical properties of the Svete River, which traverses intensive agricultural regions. Sixteen monitoring sites were selected along the main channel and at major tributary junctions. Water samples were collected monthly from surface layers (0 5 cm) over a one-year period, and concentrations of total nitrogen, total phosphorus, and selected metals were evaluated. A multi-parameter probe and an inductively coupled plasma optical ...

The oversupply of water during the floods and the low soil surface levels determine the difficult ecological, economic, and demographic conditions. It then leads to using agricultural land of different types and intensities and various methods of regulating the water regime: summer polders. Human activity has significantly impacted the ecological processes of the floodplains of the Svete floodplain with extensive amelioration works that have significantly altered the appearance of a natural park. The total area of...

The increasing world population demand for bioeconomy products intensify the nitrogen cycle and encourage eutrophication in water bodies. Global climate change and land use transformation have a significant impact on the hydrological cycle. Integrated water management in the catchment area is a sustainable solution for catchment area development and balancing economic and environmental interests. The aim of this study is to develop an optimization model for sustainable lake management. The case study is done in eu...

Changing climate variability and the type of land use are the main factors influencing the hydrological regime. The hydrological regime of the lake has a direct impact on biodiversity and has an impact on socio-economic processes in areas adjacent to the lake. The aim of the study is to predict and assess the impact of climate change and the change in the type of land use on the hydrological regime of Lake Usma. Two linear land-use change scenarios were used for modelling. Twelve climate scenarios were used to mod...
