“…In addition, during the dry seasons (winter, fall and spring) large wild fires leave burnt areas in the basin and its ashes eventually end as nutrients in the water of the lake [24]. These seasonal variation in natural and anthropogenic processes provoke changes in the composition of the phytoplankton and increase the risk for development of harmful algae species including Cyanophites, which can be toxic to human health [25].…”

“…(Nicklisch et al, 2007). The temperature measured in the water varies from 12C to 18C in the cold season (April to September) and 20C to 25C in the warm season (October to March) (Germán et al, 2016). These well distinguished seasonal and yearly changes generate large variation in the water quality of the reservoir.…”

“…These well distinguished seasonal and yearly changes generate large variation in the water quality of the reservoir. San Roque Reservoir is an eutrophic water body and this conditions lead to periodically and massive development of algae (Germán et al, 2016). As this water body is the most important source of water supply in the Province, the detection of blooms events is extremely important.…”

Abstract. Eutrophication is characterized by excessive plant and algal growth due to the increased of organic matter, carbon dioxide and nutrients in water body. Although eutrophication naturally occurs over centuries as lakes age, human activities have accelerated it processes and caused dramatic changes to the aquatic ecosystems including elevated algae blooms and risk for hypoxia as well as degradation in the quality of drinking water and fisheries. Monitoring eutrophic processes is therefore highly important to human health and to the aquatic environment. However, the spatial and seasonal distribution of the phenomena and its dynamic are difficult to be resolved using conventional methods as water sampling or sparse acquisition of remote sensing data. This research work proposes a methodology that takes advantage of the high temporal resolution of Sentinel-2 (S2) for monitoring eutrophic reservoir. Specifically, it uses large temporal series of S2 images and advanced temporal unmixing model to estimate the abundance of [Chl-a] and algae species in San Roque reservoir, Argentina, in the period August 2016 to August 2019. The spatial patterns and the temporal tendencies of these aquatic indicators, that have a direct link to Eutrophication, were analysed and evaluated using in situ data in order to assess their contribution to the local water management.
