Regular change in climate affects the existence of water on Earth. With the presence of remote sensing techniques, it became easy to analyze water bodies on Earth. There have been numerous techniques used to discernment water bodies from high-resolution satellite imagery. To get accurate results, it is essential to eliminate the effect of the forest, clouds, shadow, and constructed area from input imagery. Some of the most commonly used methods are segmentation and morphology technique, single-band threshold method, Multi band spectral relationship method, supervised classification, unsupervised classification and numerous water indices methods (Normalized Difference Vegetation Index, Normalized Difference Water Index, Modified normalized difference waters index and Automated Water Extraction Index with shadow & non-shadow variants). This paper review the diverse approach of water body delineation that accomplished on the Saryu River around Ayodhya, Uttar Pradesh, India region. All the multi-spectral imagery data accumulated by Landsat-8 (OLI) satellite on 2nd February 2019 has used in the assessment.
