Towards a multi-basin SWAT model for the migration of nutrients and pesticides to Puck Bay (Southern Baltic Sea)

Abstract: Background This paper analyzes the impact of changes in fertilization on crop yields and the runoff of nutrients from a small agricultural catchment (176 km2) to a shallow bay, using the SWAT model. Puck Bay is part of the Gulf of Gdansk and belongs to the Baltic Sea. The whole area of Puck Bay (364 km2) is protected (Natura 2000) yet despite this it suffers from eutrophication problems due to the relatively minimal depth and difficult water exchange. Met… Show more

“…This area is mainly used for agriculture. Cropland covers 60% of the area, forests 29% and urbanized areas 11% (Wielgat et al, 2021). This study is focused mainly on small rivers in Puck commune and watercourses flowing through the Nature Reserve "Beka" (NRB), because small catchments respond much faster to pollutant inflow, which is especially important when agricultural use dominates and fertilizers are washed from fields with rain (Kyllmar et al, 2014).…”

“…Due to the fact that modeling of surface runoff requires the use of a hydrological model, The Soil & Water Assessment Tool (SWAT) software was used [22][23][24]. SWAT is a small watershed to river basin-scale model used to simulate the quality and quantity of surface and ground water and predict the environmental impact of land use, land management practices, and climate change.…”

“…According to sources [ 12 , 13 ], approximately 80% of pollution in the marine environment is land-based. The contaminations reaching seas and oceans originate mainly from human activities conducted inland and, to a lesser extent, along the coasts [ 14 ]. The natural source and means of transport for all harmful substances and garbage from the hinterland to the sea are rivers [ 15 , 16 ].…”
