InSAR for Water Quality Assessment: Monitoring Cyprus’s Reservoirs
As water scarcity and environmental concerns grow, innovative methods for monitoring and managing aquatic ecosystems are increasingly essential. Interferometric Synthetic Aperture Radar (InSAR) offers a groundbreaking approach to water quality assessment, enabling remote, efficient, and accurate monitoring of reservoirs and other water bodies.
In Cyprus, InSAR technology has been applied to assess the water quality of two major reservoirs: the Asprokremmos and Kouris reservoirs. These studies highlight the transformative potential of satellite-based measurements, providing a cost-effective and expansive alternative to traditional field sampling techniques. By analysing satellite data, researchers gained detailed insights into the reservoirs' water quality, contributing to better water resource management and environmental conservation.
Satellite Remote Sensing for Water Quality Measurement
Why InSAR is Ideal for Water Quality Assessment
Water quality is a critical indicator of environmental health, directly impacting ecosystems, human consumption, and agricultural use. Key parameters like chlorophyll-a, Total Suspended Solids (TSS), and turbidity are often used to assess water clarity, nutrient levels, and ecosystem productivity.
Traditional water quality assessments rely on in-situ sampling and lab analysis, which, while accurate, are often limited in scope and frequency. InSAR and other satellite-based methods offer an alternative by providing:
-
Large-scale monitoring across entire water bodies.
-
Frequent and consistent updates that enable real-time tracking of water quality changes.
-
Cost-effectiveness, as satellite data eliminates the need for extensive fieldwork.
Chlorophyll-a, a pigment present in phytoplankton, serves as a proxy for nutrient levels in aquatic ecosystems. High concentrations can indicate algal blooms, often caused by pollution or eutrophication, which can harm water quality. Similarly, TSS and turbidity are critical in determining water clarity, with higher levels indicating potential ecological stress.
By leveraging InSAR technology, researchers can remotely monitor these parameters with remarkable precision. This capability is especially valuable in regions like Cyprus, where water resources are under significant pressure due to climate change and increasing demand.

The application of InSAR for water quality monitoring in Cyprus demonstrates the transformative potential of satellite remote sensing technologies. By providing accurate, large-scale, and cost-effective assessments, InSAR empowers stakeholders to make informed decisions about water resource management and environmental conservation.
As this technology continues to evolve, its role in safeguarding water quality will only grow, offering a scalable solution to meet the challenges of a changing world. Whether in Cyprus or beyond, InSAR is poised to become an indispensable tool in the quest for sustainable water stewardship.
