AUTOMATIC ASSESSMENT OF LAKE STATUS USING AN OPEN SOURCE APPROACH: LAKE LUGANO’S CASE STUDY

Our results demonstrate the importance of oxygen in regulating the fate of nitrogen (N) in the sediments of Lake Lugano south basin, Switzerland. Hence, our study suggests that, by changing oxygen concentration in bottom waters, the seasonal water column turnover may significantly regulate the partitioning between N removal and N recycling in surface sediments, and it is likely that a similar pattern can be expected in a wide range of environments.

A glacial lake outburst flood hazard assessment by satellite Earth observation and numerical modelling was done for the lakes linked to the Thangothang Chhu glacier, Chomolhari area (Bhutan), combining detailed geomorphological mapping, landslide and rock glacier inventories, as well as surface displacements quantified by satellite InSAR. Outburst scenario modelling revealed that only a flood wave can have an impact on the two human settlements located downslope of the glacier.
