could lead to erosion that could affect the river basin and the river itself. The Unac river is prone to sudden increases of discharge and water level, which could also lead to additional erosion. In the cities and towns located on the river banks, most of the local population lacks any sort of ecological consciousness, which, combined with the lack of public trash cans and the ongoing migrant crisis, leads to a large amount of trash being thrown onto the river banks and into the river itself. Commons sites where large amounts of trash can be found are bathing sites, especially more obscure ones, the intake of the hydroelectric power plant in Bihać, publicly accessible river islands, and the shallower parts of the river. Completely destroyed trash cans, park benches and vandalized bridges are not an uncommon sight, especially in more obscure, badly lit parts of the cities. Some of the vandalized bridges on the river even required complete reconstruction. Another large but often overlooked issue is the fact that there are multiple illegal landfills located in the watershed of the river, most notable in the Una-Sana canton. Some of the landfills are located directly above spring which feed directly into the river itself. To this date, there have been no solutions to the problem as the government of the Una-Sana canton is unable to properly organize and find a suitable location for a canton-level landfill. Hydropower projects There have been multiple hydropower projects proposed on the rivers itself and its tributaries, including the large Unac, Vrhpolje and Ključ hydroelectric power plants, and the smaller Štrbački buk power plant. There have also been multiple proposals for smaller mini hydroelectric power plants along the smaller tributaries, such as the Dobrenica. Some of those power plants, like the Unac power plant, would have large dams that would flood attractive canyons while other would divert a large portion of river's water to a machine room several kilometers downstream, leaving large parts of the riverbed dry. All of those proposals were met with fierce resistance from the local and international communities for fear of the destruction of the river's unique environment and, eventually, were cancelled.
