Description :
About 40 lake and 25 river bifurcations in Finland are described in this article. According to their location, the bifurcations can be classified to external and internal bifurcations. An external bifurcation is located on the divide, either between two river basins or between two subbasins. An internal bifurcation occurs within a river basin or subbasin. The branches of an internal bifurcation have a junction downstream| if at least one branch has a tributary before the junction, the bifurcation is an ordinary internal bifurcation. If the discharge in both branches remains unchanged, the branching is called pseudobifurcation. Some of the bifurcations are temporary| 14 lake and 16 river bifurcations can be considered perennial. Some of lake bifurcations and about half of river bifurcations are manmade.
