Clear blue water
Recent water quality measurements for the Asprokremmos and Kouris reservoirs in Cyprus were needed without the need for a site visit, sampling and laboratory testing.
Satellite image analysis for a recent time series allowed rapid measurement of total suspended matter and chlorophyll-a concentration across almost the whole surface area of these reservoirs.
Conventional water sampling and testing methods are slow and expensive and cannot be performed retrospectively.
A time series of satellite images was analysed to obtain regular data of total suspended matter and chlorophyll-a concentration.
Data from almost the entire surface area of the reservoirs was obtained without needing to visit the site.
