Analysis of modelling water quality in lakes and reservoirs

Water quality in lakes is analyzed in this study. It deals with modeling of long residence times in water bodies, natural or man-made. The key driving force of Lake Dynamics is usually temperature. Its vertical distribution defines whether a lake is stratified or not. The result shows that runoff process is involved the biochemical oxygen demand concentration of the lake water is reflected mainly by the subsurface runoff component, suspended solid (ss) concentration is affected mainly by the surface runoff component.
