“…The increase in lake volume during mixing periods ranged from ~10 to 92% with a mean of 41% and a standard deviation of 23%. The mean difference in temperature for all mixing events was 2.5°C with 1.3°C standard deviation, computed by an empirical regression between inflow and air temperatures if inflow temperature is uniformly spread from the inlet (Kimura et al, 2014). The mean and standard deviation value for inflow temperatures can be ~10% and 5% of the entire lake temperature during typhoons.…”

“…The flows, surface waves and sediment resuspension in the shallow lakes are significantly driven by wind forcing (Kjaran et al 2004;Kimura et al 2014;Scheon et al 2014). Podsetchine and Huttula (1994) addressed the correlation and time lag of wind direction/speed to resuspended sediment in the Lake Karhijärvi, Finland.…”

A three-dimensional, unstructured-grid hydrodynamic and suspended-sediment transport model was developed to simulate the temporal and spatial variations of suspended sediment and was applied to the subtropical subalpine Tsuei-Feng Lake (TFL) of Taiwan. The model was validated with measured water level and suspended-sediment concentration in 2009, 2010 and 2011. The overall model simulation results are in quantitative agreement with the observational data. The validated model was then applied to explore the most important parameter that affects the suspended-sediment concentration and to investigate the effect of wind stress on the mean current and suspended-sediment distribution in this shallow lake. Modelling results of the sensitivity analysis revealed that the settling velocity is a crucial parameter and the erosion rate is less important in the suspended-sediment transport model. Remarkable lake circulation was found based on the strength of wind speed and wind direction. A strong wind would result in a higher mean current in the top layer and suspended-sediment distribution in the top and bottom layers. This study demonstrated that wind stress played a significant influence on mean circulation and suspended-sediment transport in a shallow lake.

A three-dimensional, unstructured grid, hydrodynamic and suspended-sediment transport model (i.e., SELFE-SED) was developed to simulate temporal and spatial variations of suspended sediment and was applied to the subtropical subalpine Tsuei-Feng Lake (TFL) of Taiwan.

Remarkable lake circulation was found based on the strength of wind speed and wind direction.

This study demonstrated that the wind stress played a s ignificant influence on mean circulation and suspended-sediment transport in a shallow lake.
