Turbulence is a key process regulating the exchange of matter and momentum not only across the water-gas interface, but also within water columns. It is also a driving force for the resuspension of sediments and the evolution of shallow lake ecosystems. The dissipation rate of the turbulent kinetic energy (ε) is a key physical quantity which depicts the evolution of the turbulent kinetic energy, and discriminates turbulence production rate from mechanisms in water bodies. Based on observations for profiles of three-dimensional currents using Acoustic Doppler Current Profiles (ADCP) and records on water temperature and the wind field in Lake Taihu from October 29, 2017 to November 2, 2017, the profile features of ε in this large-scale shallow lake were explored. The horizontal ε is about 10^-8-10^-7 m²/s³ below 0.7 m water depth, about one order of magnitude larger than the vertical ε. Despite the shallowness of the lake, there are still three typical layers of ε for u',v', and w':the wind-wave layer, where the water depth is shallower than 1.0 m, exhibits that ε decreases with depth due to wind forcing, Langmuir turbulence and wave breaking; constant layer, in the range of 1.0 m to 1.9 m or so, shows that ε is little variation with the depth; bottom boundary mixed layer, below the constant layer, exhibits that ε decreases with depth. In Lake Taihu, the strength and location of stratification significantly contribute to ε in the constant layer and the bottom boundary, and even cause the initial depth of the constant layer of ε to move downward. This study will help to further understand the kinetic process of large shallow lakes and their evolutionary effects on aquatic ecosystems.
