Inverkan av värmeuttag på temperatur- och cirkulationsförhållanden i istäckta sjöar
Three different circulation mechanisms are analyzed: 1) through-flow of a river; 2) wind generated oscillations; and 3) convective currents induced by heat flow from the bottom sediments. The through-flow takes place between the ice and a depth, which is mainly determined by the conditions at the inlet of the river into the lake. Just below this depth there is a sharp thermocline. The water mass b
