Characteristics and driving factors of thermal stratification evolution in Daheiting Reservoir

Thermal stratification which is common in water bodies subject to such factors as the depth of body (a lake or reservoir, for instance), fluidity and local meteorological conditions. The stable thermal reservoirs will lead changes physical chemical properties well distribution aquatic creatures, hence leaving an impact on quality. Daheiting Reservoir was taken research object this study. Based continuous monitored temperature data tempo-spatial change features structure reservoir were analyzed, driving studied. found that air temperature, wind speed, hydrodynamic are corresponding patterns Reservoir. Among these factors, fundamental precondition, speed auxiliary disturbance All act together cause pattern evolution
