Effects of Boundary layers on mixing in small Lakes

摘要: Abstract Ottesen Hansen, N.-E., 1978. Effects of boundary layers on mixing in small lakes. An analysis lee effects and layer the two layered lakes is presented. Especially can be exposed to these resulting decreased rates compared with greater The surface wind shear stress may very unevenly distributed over lake due effects. Typically trees, rocks, hills etc. it will remain zero a length 6 times height sheltering feature further distance 7 height, grow its fully developed value. In front giving features corresponding 2 height. It shown that winddriven flows have character lengths 15–30 depth upper depending distribution between different areas negligible. Analytical expressions for are presented as functions Richardson Numbers, fetch ratios. They found reasonable agreement measurements. Finally dominated by through-flow considered.
