Abstract
The conventional method used to measure the pollution level of water is by collecting samples and analysing them in the lab. This method is not efficient and cannot provide a real-time result, whereas, digital image processing and remote sensing techniques have been widely used in estimating and mapping water pollution levels in vast areas. Various algorithms have been developed and used for the measurement of the water pollution level. In this work, an algorithm developed for remote sensing techniques is used. The technique employed involves radiating the samples with a laser and then correlating the backscattering with water pollution level. A laser emitting multiple wavelengths are radiated into the water sample and backscattering radiations for every wavelength are analysed and corelated with the polutant concentration. The backscattering radiation is then analysed and the proposed water quality algoritm is calibrated for measuring the pollution level of the samples.
