“…Some impairments are highly dynamic (e.g., HABs, loss of dissolved oxygen, etc. ), which has resulted in the rapid proliferation of EWS for monitoring key variables that can cause rapid changes in the water quality of coastal water [5] and freshwater systems [6][7][8][9][10].…”

To assess water quality (WQ) online for assuring the safety of drinking water, a novel early warning system integrating a high-frequency monitoring system (HFMS) and data quality control (QC) was developed at Lake Qiandao. The HFMS was designed for monitoring water quality, nutrient inputs by main tributaries, water currents and meteorology at different sites at Lake Qiandao. The EWS focused on data availability, a QC method, a statistical analysis method and data applications instead of technological aspects for sondes, wireless data transfer and interface software development. QC was implemented before use to delete the abnormal values of outliers, to detect change points, to analyse the change trend, to interpolate discrete missing measurements, and find continuous missing or wrong observations caused by technical problems with the sonde. For demonstrating advantages and data availability, surface and profiling measurements at two sites were plotted. The plots show obvious seasonal and diel variations, demonstrating the success of integration of the system with advanced automated technology and good QC. This successfully developed system is now not only giving early warning signals, but also providing critical WQ information for the security of drinking water diverted to Hangzhou city through a tunnel of 110 km length. The automatic monitoring data with QC is also being used to produce initial conditions for WQ prediction based on a three dimensional hydrodynamic-ecosystem model.

“…Compared to deep lakes, they have more vulnerable ecosystems; not only its ecosystem services but also its balance of water supply and demand are more susceptible to be disturbed. In addition, shallow lakes usually have a low pollution load capacity, making them prone to eutrophication (María et al, 2013;Wang et al, 2009Wang et al, , 2013Wu et al, 2014). Therefore, the promotion of a harmonious development between the environment and the eco-efficiency has become an important issue.…”
