Remote Sensing of Water Quality in Waste-Water Reservoirs: Pilot Plant Studies

A German-Israeli program is currently being carried out at the Hebrew University, applying infrared imaging for the monitoring of waste-water reservoirs. The images were processed together with surface sampling data, in order to develop regression equations. Limnological parameters selected for the study were related to hypertrophic conditions existing in waste-water reservoirs, such as chlorophyll concentration and water turbidity. Regression equations were established and proved reliable for pilot plant performance. Additional field work is needed in order to validate pilot plant models. The long-term goal of this project is developing on-line reservoir surveillance for the monitoring of water quality.
