Understanding seasonal water clarity dynamics of Lake Dahuchi from In Situ and remote sensing data por Wu, G., Leeuw, Jan de, Liu, Y.

“…Piecewise linear regression analysis between water clarity and water level showed that water level could explain 70% of the variation of the logarithm of Secchi disk depth. The water clarity of Lake Dahuchi was primarily controlled by suspended sediment, while the seasonal variation of water level induced different sediment resuspension, thus we concluded that the water clarity seasonal dynamics of Lake Dahuchi was mainly regulated by seasonal variation of water level.…”
