Abstract: | During recent decades, Lake Koronia has undergone severe degradation as a result of human activities around the lake and throughout
the basin. Surface and groundwater abstraction and pollution from agricultural, industrial, and municipal sources are the
major sources of degradation. Planning a restoration project was hampered by lack of sufficient data, with gaps evident in
both spatial and temporal dimensions. This study emphasized various remote sensing and geographic information system techniques,
such as digital image processing and geographic overlay, to fill gaps using satellite imagery and other spatial environmental,
hydrological, and hydrogeological data in the process of planning the restoration of Lake Koronia, following Ramsar guidelines.
Current and historical remote sensing data were used to assess the current status and level of degradation, set constraints
and define the ideotype for the restoration, and, finally, define and select the best restoration scenario. |
